ITEM 1.  BUSINESS

GENERAL
Burr-Brown  Corporation (and its wholly-owned subsidiaries  and
majority-owned  affiliated  companies,  "Burr-Brown"   or   the
"Company")   is   a  world-wide  leader  in  the   development,
manufacturing, and marketing of electronic components including
precision  linear, data converters, and mixed signal integrated
circuits  (ICs). These products address applications  for  both
analog  and  digital signal processing relating to  industrial,
communications, consumer, and computing markets.

The  Company  offers over 1,200 high performance products  that
perform  analog  signal  processing  functions  such   as   the
conditioning,  amplification, and  filtering  of  signals,  and
mixed signal processing functions such as analog-to-digital and
digital-to-analog conversion. Within its targeted markets, Burr-
Brown  emphasizes  high  performance  applications  where   its
products   are   critical  elements  of  the  overall   systems
architecture. The Company was incorporated in Arizona  in  1956
and   reincorporated  in  Delaware  in  1983.   The   Company's
management  and technical team has many years of experience  in
the  design, development, manufacture, and world-wide marketing
of  high  performance  analog  and mixed  signal  semiconductor
components,   and   in  providing  unique  and   cost-effective
solutions to the complex signal processing requirements of  its
target markets.

THE INDUSTRY
Integrated  circuits  may  be divided  into  three  categories:
analog,  digital,  and mixed signal. Digital circuits  such  as
memory devices and microprocessors, use many repetitive circuit
elements, each of which can represent the two values  ("1"  and
"0") required by the binary number system that is the basis for
most  computation.  Analog circuits, on  the  other  hand,  are
capable of representing an infinite number of values based on a
continuously varying signal. These signals typically  represent
"real world" phenomena such as temperature, pressure, position,
light,  speed,  and sound. Mixed signal circuits  are  circuits
that   employ   both  analog  and  digital  signal   processing
techniques. Analog and mixed signal circuits are used  in  most
electronic systems and major markets for such circuits  include
telecommunications, data communications, test and  measurement,
medical    instrumentation,   industrial    process    control,
manufacturing automation, digital audio and video, and personal
computers.   Typical   analog  circuits   include   operational
amplifiers,   instrumentation  amplifiers,  programmable   gain
amplifiers,    current   transmitters,    regulators,    analog
multipliers,  and  isolation amplifiers. Typical  mixed  signal
circuits   include  analog-to-digital  converters  (ADCs)   and
digital-to-analog  converters  (DACs).  The  technology  trends
driving  the  growth of digital ICs, such as increased  use  of
microprocessors,   portability,  lower  power   consumption,and
higher  speed  requirements are also driving  demand  for  high
performance  analog and mixed signal ICs. Recently,  the  rapid
growth  of  the  high  speed wired and wireless  communication,
multimedia,  portable computing, and digital  audio  and  video
markets  have  created important new growth  opportunities  for
high  performance analog and mixed signal products. IC Insights
Inc.  estimated that analog and mixed signal circuits accounted
for  17  percent  of  the  $109 billion market  for  integrated
circuits in 1998.

The  market, design, and manufacture of analog circuits  differ
from  those of digital circuits in several important  ways.  In
general, the markets for analog circuits are more diverse  than
for digital circuits, with each application requiring different
operating  specifications  relating to  resolution,  processing
linearity, speed, power, and signal amplitude. As a result, the
customers   for  analog  and  mixed  signal  circuit   products
generally  have  relatively  smaller  volume  requirements  per
application.  The  markets for analog  circuits  are  generally
fragmented,  and  competition within  those  markets  tends  to
depend   less   upon   price   and   more   upon   performance,
functionality, quality, and reliability. Analog circuits are
often  characterized  by  longer life cycles  and  more  stable
pricing  compared  to  typical  digital  circuits.  Given   the

<PAGE> 2

diversity  of  applications, analog product lines  tend  to  be
broader  and have broader customer bases than digital circuits.
This is one of the reasons for the historic stability of analog
and  mixed  signal  IC  business  as  compared  to  digital  IC
business.  Furthermore, analog product lines are  characterized
by  a  higher proportion of proprietary designs that  introduce
switching  costs  to  customers  after  design-in,  tending  to
minimize  competition  based  on  price  alone.  Computer-aided
design  and  engineering  tools, which  have  proliferated  and
enhanced the design effort for digital integrated circuits, are
less  effective for analog devices. Accordingly, analog circuit
design  has  traditionally been highly dependent on the  skills
and  experience  of  design engineers.  Also,  in  contrast  to
digital  circuits, the performance of analog circuits  is  more
dependent  on circuit design, circuit layout, and the  matching
of  circuit  elements than on the density of  circuit  elements
which requires advanced capabilities in submicron semiconductor
processes.  Consequently, the production  of  high  performance
analog  circuits  typically requires  relatively  less  capital
investment  than  the production of highly  integrated  digital
circuits.   Because analog and mixed signal circuits are  found
in  most  electronic systems, the growth in the use of  digital
systems across a broad range of applications has in turn fueled
a  growth  in the demand for analog and mixed signal integrated
circuits.

PRODUCTS
The Company operates in the electronic component industry where
its  revenue  is  derived from the sale of the  Company's  full
array of products.

The following table shows the approximate product line revenues
as a percentage of total Company revenues:

<TABLE>
<CAPTION>

     PRODUCT LINE             1998       1997     1996
     ------------             ----       ----     ----
     <S>                      <C>       <C>       <C>

     Mixed Signal Products    50.5 %    49.0 %    45.4 %
     Other                     4.3 %     4.8 %     7.3 %

</TABLE>

Demand  for  analog circuits primarily has been driven  by  the
need  for  increased productivity manifested as  the  need  for
lower   cost,  faster,  lower  power,  smaller  size,   greater
functionality,  and  higher precision products.   Semiconductor
technology  has  provided  many  effective  solutions  to  this
demand. The availability of effective solutions has accelerated
with  the advent of more advanced digital processing. This  has
led  to  greater  use  of digital computers  or  processors  to
provide  massive computational power to control  processes  and
equipment   and   in   general,  to  greater   automation   and
productivity  in the industry. Since the early  seventies,  the
availability  of  low cost digital microprocessors,  and  later
digital  signal processing in cost-effective single chip  form,
has   enabled   an  acceleration  of  the  trend   toward   the
digitization  of  systems. This has led  to  increased  use  of
computers as embedded processors to measure, control,  monitor,
or  process electronic signals nearer or adjacent to the sensor
that  is  detecting  physical conditions. This,  in  turn,  has
created  the  need for products that enable digital  computers,
microprocessors,  and  microcontrollers,  and  digital   signal
processors (DSP's) to interact with electronic signals  derived
from  physical  or  analog phenomena.  Burr-Brown  designs  and
manufactures  the integrated circuits that perform  the  analog
signal  conditioning and data conversion functions critical  to
this interaction.

Process   control   sensors   generate   continuously   varying
electronic  signals,  called analog or  linear  signals,  which
represent the physical phenomenon being measured or controlled.
In  many circumstances these analog signals are relatively weak
and contaminated with a large amount of electrical "noise". The
Company's  signal processing components are used to strengthen,
filter,  transmit,  and  otherwise condition  the  signal.  The
resulting signal, still in analog form, must be converted  into
a  digital  signal  before  a  computer  can  process  it.  The
Company's  ADCs  effect  this conversion.  After  the  computer
processes the digital signal, it is often necessary to  convert
the  digital signal back to analog form, and the Company's DACs
also  accomplish this reverse conversion. The resulting  analog
signal controls the process.

The  market requirements for analog signal processing and  data
conversion  products  range  from high  performance  industrial
applications   to   high  volume  consumer  applications.   The
Company's   product  strategy  has  been  to   concentrate   on
proprietary,  high  precision, high  performance  analog,  data
conversion,   and  integrated  analog/digital  (mixed   signal)
circuits.  The Company identifies significant markets in  which
new  or  enhanced high performance products of  this  type  are
required.   The Company then attempts to develop and supply  as
complete  a function as is permitted by technological and  cost
constraints.

The Company's products are generally designed into a customer's
product  and  usually remain a part of that product  throughout
its  life.   The  Company's experience has been that  there  is
generally a two to four year period before the sales  level  of
its  standard products fully matures, and the sales life of  the
products may extend from five to eight years or more 

<PAGE> 3

once they have reached mature production volumes.  Once  the  
Company's component  has  been  designed into a customer's  
product,  the  relatively  low  volume,  high  performance 
characteristics of the component  significantly  deter potential  
competitors.  As a result,  the  Company  is often a customer's  
sole or primary source for that particular component.

The   Company's  products  can  be  grouped  into   two   broad
categories:  standard  linear integrated circuits  (SLICs)  and
application  specific  standard products  (ASSPs).   SLICs  are
products that are used by a wide range of customers in a  broad
variety of applications.  It takes longer for these products to
reach  peak revenue levels, but product life cycles tend to  be
long  and  demand relatively stable.  ASSPs target the specific
application  needs  of  a more limited  customer  base.   ASSPs
represent  a  more  complete solution to  specific  application
needs,  using standard products as building blocks  to  achieve
this higher level of functional integration.  This affords  the
Company  an  opportunity to further leverage its  Research  and
Development  investment.   ASSPs generally  have  shorter  life
cycles  and a shorter time to peak revenues.  The Company  uses
ASSPs  to  target high volume applications within  all  of  its
served  markets  for communications, consumer,  computing,  and
industrial  ICs.   In  1998,  1997 and  1996,  ASSPs  generated
approximately   32  percent,  30  percent,  and   23   percent,
respectively,  of the Company's revenue.  It is  the  Company's
strategic intent to expand this to half of the total revenue by
targeting  large  and  rapidly  growing  applications  and   by
focusing more development activity on ASSPs.

ANALOG INTEGRATED CIRCUITS
The  Company's analog circuits include operational  amplifiers,
power amplifiers, instrumentation amplifiers, programmable gain
amplifiers,  isolation  amplifiers, current  transmitters,  and
other   analog  signal  processing  components.  Analog  signal
processing integrated circuits are used to process and transmit
analog  data  signals  prior  to their  conversion  to  digital
signals. These components are used in communications equipment,
automatic  test  equipment,  analytical  instruments,   medical
instruments   and   systems,  industrial   controls,   personal
computing, and computer peripherals.

OPERATIONAL  AMPLIFIERS. Operational  amplifiers  are  used  to
detect  and  amplify weak (low level) analog  signals  and  are
included  in  many  systems. The operational amplifier  is  the
fundamental  building  block  in  analog  and  digital  systems
design.   In  addition to amplification, operational amplifiers
can  perform  mathematical functions such  as  integration  and
differentiation.  The  Company's high  performance  operational
amplifiers  are generally capable of amplifying typical  analog
signals in the micro-volt range up to 100,000 times and provide
ultra-low  drift, low bias current, low noise, high  bandwidth,
and  fast  settling time.  Certain models provide high  voltage
and   high  current,  or  high  speed  operation  for   special
applications.  These high performance amplifiers  are  required
to  treat signals generated in numerous applications, including
satellite  and  cable  TV  systems, audio  and  video  systems,
robotic   systems,   magnetic  resonance,  and   computer-aided
tomography (CAT) body scanning systems.

OTHER  AMPLIFIERS. The Company manufactures a number  of  other
amplifiers,  including instrumentation amplifiers, programmable
gain  amplifiers,  and  isolation amplifiers.   These  products
perform a variety of functions related to the amplification and
isolation   of  analog  signals.   Among  other   uses,   these
components  permit  the  measurement of  weak  signals  in  the
presence  of unwanted "noise" and protect sensitive instruments
from  the  effects  of  transient, high-magnitude,  potentially
damaging  voltages caused by sources such as lightning  or  the
switching of high voltage equipment.  These amplifiers are used
in  many diverse applications including temperature measurement
in   industrial  processes,  protection  of  sensitive  medical
instruments,   and   isolation   of   electrical   power   line
disturbances and faults.

OTHER SIGNAL PROCESSING AND TRANSMITTER COMPONENTS. The Company
manufactures  a  variety  of  other  analog  signal  processing
components,  including mathematical function circuits,  current
transmitters, and voltage-to-frequency converters.  Mathematical 
function circuits are  used  when  information  sought can  be  
effectively derived only through its mathematical relationship  
to  analog  signals.  Current  transmitters  send analog signal 
information from a process sensor to measurement or control 
equipment in the form of a current on the same wires that produce 
the power to the transmitter and sensor.  Voltage-to-frequency 
converters convert process signal amplitude  to  a frequency,  
making  the signal immune to electrical  noise  and permitting  
more  efficient  storage  and  processing of the information.

ISOLATION PRODUCTS.  The Company's isolation products focus  on
the design, development, production, and marketing of isolation
amplifiers, isolated digital couplers, and DC-to-DC converters.
These  products provide galvanic isolation of input and  output
signals  and thereby achieve reduced circuit noise interference
and prevent harm to people or equipment due to high voltage
transients  or  current  leakage.  The  product  line  utilizes
optical,  transformer,  and capacitive  techniques  to  produce
linear transfer functions between input and output.  In certain
products, isolated digital couplers are used in lieu  of  

<PAGE> 4

opto-couplers  in  the  galvanic isolation  of  data  signals.   
The isolation  products  are  used in industrial  process  control,
communication, and in medical instrumentation among others.

DATA CONVERSION PRODUCTS
The  Company's data conversion products are integrated  circuit
devices  used to convert analog signals to digital form  or  to
convert  digital  signals to analog form.  This  conversion  is
necessary  in  virtually  all  applications  in  which  digital
computers or processors measure and control the analog  signals
from a physical, "real world" process.

PRECISION  DATA  CONVERSION  PRODUCTS.  The  majority  of   the
Company's  mixed  signal  components revenue  is  derived  from
moderate  speed, high resolution, and high accuracy converters.
These general purpose converters are used primarily in  process
control   instrumentation,  electronic  test   instrumentation,
automatic   test  systems,  and  communications  systems.   For
example,  in a robot controller, the position of the robot  arm
must be precisely measured and manipulated. Analog signals from
the  robot's position sensors are converted by an A/D converter
for  computer processing and, in turn, a D/A converter converts
the digital control signal from the computer to analog form  to
drive the actuators and servo motors to position the robot  arm
accurately.

HIGH  SPEED DATA CONVERSION PRODUCTS. In the early 1980's,  the
Company  began developing high speed, high resolution  A/D  and
D/A  converters at speeds substantially greater  than  general-
purpose  products. These products utilize a unique  combination
of  technologies and design expertise to achieve  state-of-the-
art performance. High speed converters are used in a variety of
applications  such  as wireless communications  systems,  image
processing,  digital  oscilloscopes,  ultrasound,  radar,   and
sonar, as well as the front end of other advanced systems using
digital signal processing (DSP) technology.

DIGITAL  AUDIO  AND  VIDEO  PRODUCTS.  The  Company's digital
audio  and  video  products  focus  on  the   design,
manufacturing,  and marketing of high precision,  single  chip,
digital-to-analog  converters,  analog-to-digital   converters,
codecs,  and  video signal processing devices for  the  digital
audio  and  video market. The Company believes that  Burr-Brown
was  the  first  company to introduce such audio products  into
this  marketplace and is currently one of  the largest merchant
market  suppliers of  such  devices worldwide. One  product,  a
pulse-code-modulated  ("PCM")  conversion  device,   plays   an
essential  role in digital audio systems, such as compact  disc
("CD")  players, that use laser technology to achieve  improved
audio   reproduction   performance.  The  Company's   component
converts  the  digital  signals for each  stereo  channel  into
audio.  Several generations of products of this type have  been
developed  and  introduced for use in  digital  audio  systems.
Involvement  in  the CD market also helped the Company's  early
entry  into  the  Digital Versatile Disk (DVD)  and  multimedia
markets.  Burr-Brown's PCM converters have  now  been  designed
into  musical  instruments, computer  games,  automobile  sound
systems,  CD-ROMs  for  multimedia applications,  set  top  box
tuners  for  cable  and satellite TV, DVD  players,  PC  add-in
cards,  camcorders,  and digital cameras.  The  Company's  high
speed  analog-to-digital converters are used in charge  coupled
device ("CCD") imaging applications such as camcorders, digital
cameras  and  scanners  to convert the  CCD  analog  signal  to
digital  for  processing in the system DSP.  In addition,  this
has  made complete "front-end" video   ASSPs, combining analog-
to-digital  with  other  circuity  to  handle  all  the  signal
processing  between  the CCD sensor and  the  system's  digital
processor.

SYSTEM PRODUCTS

INTELLIGENT  INSTRUMENTATION  INC. Intelligent  Instrumentation
Inc. (III), a majority-owned subsidiary, designs, manufactures,
and  markets a broad line of hardware and software products for
the  capture  and sharing of real-time enterprise  data.  These
products  capture  sensor based data as well  as  human-entered
data.   Products  include  plug-in  data  acquisition   boards,
Ethernet-based  data acquisition systems,  network  based  data
collection  terminals,  and  component  terminals  for  machine
interface. These products are applied world-wide for a range of
applications including predictive maintenance, access  control,
time  and  attendance,  material tracking,  product  test,  and
resource  planning.  Representative  customers  include  Symbol
Technologies,  Mercedes Benz, Hewlett Packard, CTI  Cryogenics,
IBM, and AMP Incorporated.

Burr-Brown   considers   III's   business   model   to   differ
strategically  from the Company's core business.   The  Company
has  from  time-to-time received indications of  interest  with
respect  to  III,  and has considered, and may  in  the  future
consider, the sale of its interest in this subsidiary in  order
to focus its resources on the core business of analog and mixed
signal integrated circuits.

RESEARCH & DEVELOPMENT
Digital  circuits have an exceptional amount of  repetition  of
circuit  elements and are highly dependent upon the ability  to
produce  chips  with  very  high  circuit  element  density  to
minimize chip size and cost, and maximize speed.  This type  of
wafer  processing of extremely small dimensions  leads  to  the
need   for   state-of-the-art,  comparatively  costly   capital
investment in wafer fabrication facilities.

Analog  circuits,  on the other hand, require  the  ability  to
accurately  match  and place transistors with  respect  to  one
another.  In addition, analog circuits may require the  ability
to  handle  large  voltages and currents and therefore,  demand
relatively  large transistors and spacing dimensions.  Although
these  requirements place stringent processing requirements  on
an  analog  wafer fabrication facility, the necessary equipment
and  facilities are substantially less costly and longer  lived
than that which is required for digital circuit processing.

Analog  and mixed signal circuit design is highly dependent  on
the  skills and experience of individual design engineers,  and
Burr-Brown  believes  that its team  of  design  engineers  has
developed  extensive core strengths in high performance  analog
and  mixed  signal  integrated circuits.  Designers  of  analog
circuits  must  take  into  account complex  interrelationships
between  the  manufacturing process, the circuit elements,  the
packaging requirements, and the customer's application, all  of
which  may  seriously  affect  the circuits'  performance.  The
number  of creative design engineers who have the training  and
the  experience  to handle these complexities is  limited.  The
Company's  ability to compete depends heavily on its  continued
introduction  of  innovative and cost effective  new  products.
Therefore,  the  Company  must  continually  invest  in  design
engineering  talent,  engineering tools, production  processes,
and test equipment.

The  Company emphasizes the development of proprietary standard
and   application  specific  products.  The  Company's  product
strategy  is  to  identify markets in which the application  of
microelectronics technology may be used to provide  competitive
advantage  for  its  customers  through  improved  methods   of
precision  measurement,  monitoring, and  controlling  physical
processes  and  conditions. Examples of these markets  include:
robotics, factory automation, process control, automatic  test,
medical instrumentation, computers, communications, and digital
audio.  Within  these  markets, the  Company  selects  specific
applications   in  which  the  Company's  unique   design   and
processing  technology will make an important  contribution  to
its  customers, often acting as the enabling technology for the
successful commercialization of end equipment.

The  Company  spent approximately $39.9 million in 1998,  $34.0
million  in  1997, and $28.5 million in 1996  for  product  and
process   development.   This  represents  an  expenditure   of
approximately 15.5 percent, 13.5 percent, and 12.9  percent  of
revenue   in   1998,   1997,  and  1996,   respectively.   (See
"Management's  Discussion and Analysis of  Financial  Condition
and  Results of Operations" in the Company's Annual  Report  to
Stockholders,  incorporated by reference  to  Item  7  of  this
report.)

The  Company introduced a record 87 new products in 1998.  Many
of  these products target emerging applications for which  high
performance  signal processing ICs are absolutely required  and
yet the cost of these ICs must be low in order to enable larger
end-market sales volumes.  By offering high performance  signal
processing ICs at an effective price, Burr-Brown has been  able
to  partner with many high-growth companies to address emerging
applications.

PATENTS AND LICENSES
The   Company   owns  approximately  160  United   States   and
international  patents  expiring from 1999  to  2017,  and  has
applications for approximately 60 additional patents pending in
the  United  States as well as patents issued  and  pending  in
several other countries. Although the Company pursues a  policy
of  maintaining a strong patent portfolio, the Company believes
that  its  success  depends primarily upon the  experience  and
creative skills of its people rather than upon the ownership of
patents. As is common in the semiconductor industry, from  time
to  time the Company has been and may in the future be notified
of claims regarding the possible infringement of patents issued
to  others, and similarly, the Company has on occasion notified
others of possible infringements of its patents.

SALES AND MARKETING

Burr-Brown markets its products in all the major markets in the
industrialized   world   through  its   direct   sales   force,
independent  sales  representatives, and  distributors.   Burr-
Brown  maintains 6 sales offices in the United States  and  has
international sales subsidiaries in France, Germany, Italy, the
Netherlands,  Switzerland,  the  United  Kingdom,  Japan,   and
Singapore.   The  Company's  direct  sales  force  is   focused
primarily  on  large corporate customers, while  the  Company's

<PAGE> 6

distributors service the needs of the Company's broad  base  of
smaller  clients.  In particular, the direct  sales  force  and
field  application engineers are focused on new  design-ins  to
enhance  the Company's long-term revenue stream.  Approximately
half  of the 1998 worldwide revenue was realized through  third
party distribution. In approximately 45 countries and the  less
significant domestic markets where the Company does not have  a
direct sales force, independent sales representatives sell  all
of  the Company's products. The majority of the Company's sales
people  hold engineering degrees and the balance have  relevant
engineering experience.

The  Company   sells its  products to a diverse  base  of  over
25,000  customers  worldwide.  Key  customers  of  the  Company
include   3COM,  Adtran,  Alcatel,  Advantest,  Beckman,   ECI,
Echostar,  Elsag  Bailey,  Ericsson, Fanuc,  Fujitsu,  Hewlett-
Packard,   Hitachi,  Honeywell,   Lucent,  Matra,   Mitsubishi,
National  Instruments, NEC, Nokia, Northern Telecom,  PairGain,
Quadrant, Sagem, Samsung, Siemens, Sony, Teradyne, Toshiba, and
Yamaha.  The  Company did not have any single customer  account
for  10  percent of sales in 1998.  The Company has  maintained
long-term  relationships with major customers in the industrial
process  control,  instrumentation, and  imaging  markets,  and
typically  serves as the sole supplier of proprietary products.
Burr-Brown  has pursued a strategy of leveraging its  strengths
in  analog signal processing and mixed signal design to develop
a  broad  line  of  standard products for  the  faster  growing
communications,  computing,  and  digital  audio  and   imaging
markets.  As a result, the Company has established key customer
relationships with leading companies in the wireless  and  high
speed  communications industry. Over 50 percent of the  revenue
in  1998 for analog and data conversion integrated circuits was
derived  from  products introduced within  the  preceding  five
years.

Sales outside the United States accounted for approximately  65
percent of total revenues in 1998, 66 percent of total revenues
in  1997,  and 66 percent of total revenue in 1996.   (See  the
note  labeled "Business Segment Data" in "Notes to Consolidated
Financial  Statements"  in  the  Company's  Annual  Report   to
Stockholders,  incorporated by reference  to  Item  8  of  this
report.)   To support its international marketing organization,
the  Company has established product development and production
facilities in Scotland and Japan.  The Company also has product
development and manufacturing at the corporate headquarters  in
Tucson, Arizona.

A  large  percentage of international sales are denominated  in
local  currencies  and the Company's foreign revenues  and  net
income   are  therefore  subject  to  currency  exchange   rate
fluctuations.  However,  the Company  borrows  funds  in  local
currencies,  maintains  a  significant  international  presence
which acts as a natural hedge, and purchases forward and option
contracts to hedge its foreign currency exposure. Some  of  the
Company's products are subject to export regulations and  other
international  trading restrictions, but the  Company  has  not
experienced  any material difficulties from these  limitations.
No   assurance  can  be  given,  however,  that  such  material
difficulties will not be experienced in the future.

BACKLOG
Burr-Brown's  products are, generally, standard  items  with  a
relatively  short  delivery cycle.  The  Company's  backlog  is
usually  three months or less of sales, although  some  portion
may  be  scheduled for delivery four to twelve months into  the
future.   Therefore,  the  order backlog  at  the  end  of  any
specific  quarter is not generally indicative of the  level  of
sales  to be expected in succeeding quarters.  It is the policy
of  the  Company to include in backlog only those  orders  that
have  firm scheduled delivery dates.  The Company's backlog  as
of  December 31, 1998, 1997, and 1996, was approximately  $46.3
million, $56.5 million, and $41.0 million, respectively.

COMPETITION
Burr-Brown   estimates  that  it  is   among   the   top   four
manufacturers  of high performance analog and  data  conversion
integrated  circuits.  The Company's major competitors  in  the
high  performance analog integrated circuits market are  Analog
Devices   Inc.,  Linear  Technology  Corporation,   and   Maxim
Integrated Products Inc.  With respect to a more limited  range
of   products,   the  Company  also  competes   with   National
Semiconductor  Corporation, Harris Corporation, Motorola  Inc.,
Texas Instruments Inc., Cirrus Logic Inc., ST Microelectronics,
Level One, Rockwell, and Sipex Corporation.

The  Company  is not aware of any significant competition  from
foreign   companies  providing  analog  and   data   conversion
integrated  circuits, however, there can be no  assurance  that
foreign competitors will not enter these markets in the future.

The  Company's PCM product line does compete with several  U.S.
and foreign manufacturers of digital audio (D/A) converters for
use  in  digital  compact disc stereo systems,  and  multimedia
systems,  including  Analog Devices Inc.,  Cirrus  Logic  Inc.,
Asahi  Kasei  Micro,  Sony Electronics  Inc.,  Hitachi  America
Limited, Mitsubishi Corporation, Wolfson Microelectronics,  and
Philips Semiconductors.  Many of these competitors have greater
financial, production, and marketing resources than Burr-Brown.

<PAGE> 7

The Company believes that competition with respect to component
products  is  based primarily on design and process innovation,
product   performance  and  reliability,   technical   service,
availability of a broad range of specialized products, standard
product availability, and on price.  The Company believes  that
reliable performance and service are more important than  price
when  the  Company is the sole source of a product.   Price  is
more  of  a  competitive factor when an equivalent  product  is
available  from  other  sources, as in the  case  of  commodity
products.

MANUFACTURING
The  Company's production of integrated circuits  utilizes  in-
house   process   technologies,  externally   purchased   wafer
processing  foundry  services, and  purchased  components  that
already  incorporate  the  desired semiconductor  manufacturing
technology.    The   Company   combines   relatively    diverse
technologies  to produce the integrated circuits  necessary  to
meet  the  stringent performance requirements of its customers.
For  example, some of the Company's integrated circuit products
combine   high   precision  linear  integrated  circuit   wafer
fabrication processing with compatible laser-trimmed thin  film
technology and dielectric isolation (DI) wafer processing.

The  Company  uses several bipolar, CMOS, and BiCMOS  processes
that  provide  circuits  for  the analog  and  data  conversion
markets.   Burr-Brown  processes have the added  capability  of
making  high  quality capacitors and trimmable  resistors  that
enable  the Company to manufacture high precision products.  In
addition  to  the  processes  at  the  Company's  Tucson  wafer
fabrication  facility,  foundries are used  for  processes  not
available  internally.  Processes  currently  used  include   a
variety of CMOS processes ranging from 3 microns to 0.5 microns
for products such as amplifiers, analog-to-digital and digital-
to-analog converters, a 2 micron BiCMOS process for PCMs, DACs,
and  ADCs,  and a very high frequency bipolar process  used  for
products such as video amplifiers.

The  Company conducts electrical testing of integrated circuits
in  both  wafer and packaged form. The combination  of  various
functional  modes makes the test process for analog and  mixed-
signal  devices particularly difficult. Test operations require
the programming, maintenance, and use of sophisticated computer-
based test systems and complex automatic handling systems.  The
Company  has special screening and qualification programs  when
high  reliability  quality  grades  are  required  by  customer
specifications.

The  Company  has  integrated circuit  assembly  operations  in
Tucson.  In addition, much of the Company's assembly demand  is
met  by  using  contract assembly companies located  in  Japan,
Taiwan,  Malaysia,  Thailand, and the Philippines.  To  achieve
lower  cost without compromising high performance, the  Company
has expanded its packaging capability to include low cost multi-
chip  module  assembly  in  its Tucson manufacturing  facility.
Following  assembly,  the Company and its subsidiaries  perform
nearly all of the final testing, marking, and inspection of the
packaged units prior to shipment to customers.

The  Company has developed and implemented its Quality  Program
to focus on customer satisfaction.  The program includes annual
satisfaction  reviews  with  customers  to  assess  improvement
priorities  and  competitor comparisons.  The  Quality  Program
also   includes  Quality  System  Certification  (ISO9001),   a
comprehensive  product/process reliability monitoring  program,
and  a  stringent  Qualification Program for new  products  and
processes.  The Company has a reputation for high  quality  and
highly  reliable products as evidenced year after year  by  the
high  satisfaction ratings reported by our customers for  these
factors.

To provide  better  service  to  its  European  and  Japanese
customers and to achieve an improved competitive position,  the
Company  maintains facilities in both regions.   In  Europe,  a
product  development  and administrative  site  is  located  in
Livingston, Scotland. This facility designs integrated circuits
for  sale in Europe and for export to other markets. At the end
of  1998,  Scotland's manufacturing activities  were  moved  to
Tucson,  Arizona to consolidate manufacturing  facilities.   In
Japan,  the  Company's  Atsugi Technical  Center,  near  Tokyo,
performs  product  development,  final  product  testing,   and
quality  and  reliability testing for  the  digital  audio  and
imaging  product  line for sale in Japan and  export  to  other
markets.

The  principal  raw  materials  used  by  the  Company  in  the
manufacture  of its monolithic integrated circuits are  silicon
wafers,  chemicals  and gases used in processing  wafers,  gold
wire  and  ceramic, metal, and epoxy packages that enclose  the
chip  and  provide  the external connections for  the  circuit.
Silicon  wafers  and other raw materials may be  obtained  from
several  suppliers.   From  time to time,  particularly  during
periods  of increased industry-wide demand, silicon wafers  and
other  materials have been in short supply.  As is  typical  in
the  industry, the Company allows for a significant  period  of

<PAGE> 8

lead time  between  order and delivery of raw  materials.   In
addition, the Company sometimes enters into long term supplier-
customer relationships with key suppliers of such materials  to
mitigate possible shortage problems.

Government regulations impose various controls on the discharge
of  certain chemicals and gases into the environment that  have
been  used  in semiconductor processing.  The Company  believes
that   its   manufacturing   processes   conform   to   present
environmental  regulations but there can be no  assurance  that
future changes in such regulations will not result in increased
costs  or impede operating performance.  The Company eliminated
the  use   of  ozone-depleting chemicals in  the  manufacturing
process on December 1, 1995.

HUMAN RESOURCES
At  December  31,  1998,  the  Company  employed  1,324  people
worldwide,   including  769  employees  in  manufacturing   and
assembly,  235  employees in research and development,  204  in
sales  and marketing, and 116 in management and administration.
Many  of  the  Company's employees are highly skilled  and  the
Company's  continued  success will  depend,  in  part,  on  its
ability to attract and retain such employees, who are generally
in   great   demand.    At  times,  like  other   semiconductor
manufacturers,   the   Company  has   had   difficulty   hiring
engineering  personnel.  The Company has  never  experienced  a
work   stoppage,   no  employees  are  represented   by   labor
organizations, and the Company considers its employee relations
to be very good.

RISK FACTORS

An  investment in the securities of Burr-Brown involves certain
risks.  In evaluating the Company and its business, prospective
investors  should  give careful consideration  to  the  factors
listed below, in addition to the information provided elsewhere
in   this   Annual  Report  on  Form  10-K,  in  the  documents
incorporated herein by reference, and in other documents  filed
by the Company with the Securities and Exchange Commission.

POTENTIAL FLUCTUATIONS IN OPERATING AND FINANCIAL RESULTS.  The
Company's  quarterly and annual operating results are  affected
by  a  variety  of factors that could materially and  adversely
affect  revenue,  net income, gross profit, and  profitability,
including  the volume and timing of orders, changes in  product
mix,  market  acceptance of the Company's  and  its  customers'
products,   competitive  pricing  pressures,  fluctuations   in
foreign  currency  exchange rates, economic conditions  in  the
United  States  and international markets, the  timing  of  new
product   introductions,  availability  of  wafers  and   other
materials  and  services,  and  fluctuations  in  manufacturing
yields.   The  Company has experienced significant fluctuations
in  the past and may likely experience such fluctuations in the
future. The semiconductor market has historically been cyclical
and subject to significant economic downturns at various times.
During   the   second  half  of  1998,  customer   demand   for
semiconductor devices declined significantly, and the Company's
operating results for this period were adversely affected as  a
result  of  this decline in demand.  It is uncertain  what  the
level of demand will be in the future for the industry and  for
the  Company's products.  Historically, average selling  prices
in  the semiconductor industry have decreased over the life  of
particular products.  If the Company is unable to introduce new
products  with higher average selling prices or  is  unable  to
reduce manufacturing costs to offset decreases in the prices of
its existing products, the Company's operating results will  be
adversely affected.  In addition, the Company is limited in its
ability  to  reduce costs quickly in response  to  any  revenue
shortfalls.

MANUFACTURING RISKS.  The fabrication of integrated circuits is
a highly complex and precise process.  Manufacturing yields can
be  impacted by a variety of factors, many of which are outside
the  Company's  control.   A  large portion  of  the  Company's
manufacturing  costs are relatively fixed and consequently  the
number  of  shippable  die per wafer for  a  given  product  is
critical to the Company's results of operations. To the  extent
the Company does not achieve acceptable manufacturing yields or
experiences  product shipment delays, its financial  condition,
cash  flows, and results of operations would be materially  and
adversely  affected. To meet anticipated future demand  and  to
utilize  a broader range of fabrication processes, the  Company
anticipates  that  it  may need to increase  its  manufacturing
capacity  at  some  future  point.  Although  the  Company  has
internal capability to produce wafers for many of its products,
it is dependent on outside wafer fabs for a significant portion
of its wafer supply. As is typical in the semiconductor industry,  
from time to time the Company has experienced disruptions in the 
supply of processed wafers  from  external fabs due to quality  
and yield problems and capacity constraints. If these outside 
wafer foundries are not  able  to produce required supplies of 
processed wafers conforming to the Company's quality standards,  
the Company's business and relationships with its customers for 
the quantities of products produced by these foundries could be 
adversely  affected.  In addition,  the  Company  relies on 

<PAGE> 9

domestic and international subcontractors to perform assembly,  
packaging, and testing services.  Disruption of these services 
could adversely  affect the Company's operations.

INTERNATIONAL OPERATIONS.  The Company desires to  continue  to
expand its operations outside of the United States and to enter
additional   international   markets,   which   will    require
significant  management attention and financial  resources  and
subject   the  Company  further  to  the  risks  of   operating
internationally.  These  risks include  unexpected  changes  in
regulatory  requirements, delays resulting from  difficulty  in
obtaining export licenses for certain technology, tariffs,  and
other  barriers and restrictions, and the burdens of  complying
with a variety of foreign laws.  The Company is also subject to
general geopolitical risks in connection with its international
operations,  such  as  political and economic  instability  and
changes  in  diplomatic and trade relationships.  In  addition,
because   most  of  the  Company's  international   sales   are
denominated  in  foreign currencies, gains and  losses  on  the
conversion to U.S. dollars of accounts receivable, and accounts
payable arising from international operations may contribute to
fluctuations in the Company's operating results. (See  "Foreign
Currency  Risks"  in the 1998 Annual Report to Stockholders  on
page 34, which is included as Exhibit 13 to this report.)

A  substantial portion of the Company's revenue is attributable
to  sales  in  Japan  and Southeast Asia. The  recent  economic
instability  in certain Asian countries has marginally  reduced
sales  into that region.  There can be no assurance  that  this
instability will not continue to affect the Company's operating
results  or  will  not have a material adverse  effect  on  the
Company's   business,  financial  condition,  cash  flows,   or
operating  results,  particularly  to  the  extent  that   this
instability impacts the sales of products manufactured  by  the
Company's customers.

RELIANCE ON INDEPENDENT SALES CHANNELS.  A significant  portion
of  the Company's sales are conducted through independent sales
representatives and distributors.  These independent organiza-
tions typically  represent product  lines  offered  by  other  
companies.   In  the  event  these  sales organizations reduced  
their  sales  efforts with respect  to  the  Company's products 
or terminated their relationship with the Company, the Company's  
operations  could be adversely  impacted  until  the Company was 
able to replace such resources.

INTELLECTUAL   PROPERTY  PROTECTION.   The  Company's   success
depends  in part on its ability to obtain patents and  licenses
and to preserve other intellectual property rights covering its
manufacturing processes, products, and development and  testing
tools. The Company seeks patent protection for those inventions
and  technologies  for  which it believes  such  protection  is
suitable  and is likely to provide a competitive advantage  for
the  Company. The process of seeking patent protection  can  be
long  and  expensive  and there can be no  assurance  that  its
current  patents or any new patents that may be issued will  be
of  sufficient  scope  or  strength to provide  any  meaningful
protection  or  any commercial advantage to  the  Company.  The
Company   may   in  the  future  be  subject  to  or   initiate
intellectual  property  litigation  in  the  United  States  or
elsewhere,   which   can  demand  significant   financial   and
management resources.

As  is common in the semiconductor industry, from time to  time
the  Company  has been, and may in the future  be  notified  of
claims regarding the possible infringement of patents issued to
others  and that it may be infringing the intellectual property
rights  of  third parties. There can be no assurance that  such
infringement  claims by third parties will not be  asserted  in
the  future or that such assertions, if proven to be true, will
not   materially  adversely  effect  the  Company's   business,
financial  condition,  cash flows, or  operating  results.  Any
litigation  relating  to the intellectual  property  rights  of
third parties, whether or not determined in the Company's favor
or  settled  by the Company, would at a minimum be  costly  and
could  divert  the  efforts  and  attention  of  the  Company's
management and technical personnel, which could have a material
adverse  effect on the Company's business, financial condition,
cash flows, or operating results.

DEPENDENCE  ON  NEW  PRODUCTS AND NEW MARKETS.   The  Company's
success  depends  upon its ability to develop  new  analog  and
mixed  signal  products  for  existing  and  new  markets,   to
introduce  such products in a timely manner and  to  have  such
products  gain  market  acceptance.  The  development  of   new
products  is highly complex, and from time to time the  Company
has  experienced  delays  in  developing  and  introducing  new
products.   Successful  product  development  and  introduction
depends  on a number of factors,  including proper new  product
definition,  timely  completion of design and  testing  of  new
products,  achievement of acceptable manufacturing yields,  and
market acceptance of the Company's and its customers' products.
Moreover,   successful  product  design  and   development   is
dependent  on  the  Company's ability to attract,  retain,  and
motivate qualified analog design engineers, of which there is a
limited  number.   There can be no assurance that  the  Company
will  be  able to meet these challenges or adjust  to  changing
market  conditions as quickly and cost-effectively as necessary
to  compete successfully.  Due to the complexity and variety of
products  manufactured by the Company, the  limited  number  of
analog  circuit  designers  and the  limited  effectiveness  of
computer-aided design systems in the design of analog circuits,

<PAGE> 10

there  can  be no assurance that the Company will  be  able  to
successfully  develop and introduce new products  on  a  timely
basis. Although the Company seeks to design products that  have
the  potential  to  become  broadly accepted  for  high  volume
applications,  there  can  be no assurance  that  any  products
introduced by the Company will achieve such market success. The
Company's  failure  to  develop  and  introduce  new   products
successfully could materially and adversely affect its business
and operating results. The Company has targeted new markets  in
which it has relatively little experience, including the market
niches   for   wireless  applications  for  the  communications
industry,  power  management  applications  for  the  computing
industry,   and   CD-ROM,  digital  imaging,   and   PC   sound
applications  for the digital audio and video  industry.  There
can be no assurance that the Company's products will adequately
meet  the  requirements  of  such  new  markets,  or  that  the
Company's products will achieve market acceptance.

DEPENDENCE ON KEY PERSONNEL.  The Company's success depends  to
a   significant  extent  upon  the  continued  service  of  its
executive  officers,  key management, and technical  personnel,
particularly  its experienced analog design engineers,  and  on
its  ability  to  continue  to attract,  retain,  and  motivate
qualified personnel.

COMPETITION.   The   semiconductor   industry   is    intensely
competitive  and  is  characterized  by  price  erosion,  rapid
technological  change,  product  obsolescence,  and  heightened
international  competition  in  many  markets.  Many   of   the
Company's  competitors  have substantially  greater  financial,
technical,   marketing,  distribution,  and  other   resources,
broader  product lines, and longer standing relationships  with
customers than the Company.  In the event of a downturn in  the
market for analog circuits, companies that have broader product
lines  and longer standing customer relationships may be  in  a
stronger  competitive  position than the  Company.  Competitors
with  greater financial resources or broader product lines also
may have more resources than the Company to engage in sustained
price  reductions  in  the Company's primary  markets  to  gain
market share.

YEAR  2000  COMPLIANCE. The  Year 2000 issue concerns  potential
malfunctions  resulting  from computer programs using  two-digit
year  codes  in  dates  instead of four-digit  codes.  This  may
result in hardware and  software not  functioning properly before
or  following  January  1, 2000,  which may  lead  to  minor  or
significant problems associated with manufacturing, distribution  
and other business operations. For many  reasons, it is difficult 
to predict or quantify the impact that the Year 2000 problem will 
have on the Company, both before and for some period after January 
1, 2000.  Among these reasons are the lack of control over third  
party providers, the complexity of testing interconnected systems, 
and the uncertainty surrounding how other parties will deal with 
liability  issues  raised by Year 2000  failures that may  occur  
despite the Company's implementation of its initiatives.  Although 
the Company is not currently  aware  of  any  material  Year  2000   
deficiencies associated  with  its  internal systems  (that  are  
not being addressed)  or  with  respect to the adequacy of third-
party systems,  there can be no assurances, due to the complexity  
of the  Year  2000  issue, that the Company  will  not  experience
unanticipated adverse consequences or material costs caused  by
undetected  defects,  including costs of potential  litigation.
The  impact of such consequences could have a material  adverse
effect  on  the  Company's  business, financial  condition,  or
results of operations.  For more detailed information on  Burr-
Brown's  Year 2000 initiative and state of readiness,  see  the
disclosure  under the section entitled "Management's Discussion
and  Analysis of Financial Condition and Results of Operations"
on   pages  30  through  32  of  the  1998  Annual  Report   to
Stockholders, which is included as Exhibit 13 to this report.

ITEM 2.  PROPERTIES
Burr-Brown  has  manufacturing and/or technical  facilities  in
Tucson,  Arizona; Atsugi, Japan; and Livingston, Scotland.   In
1994,  Burr-Brown established business units in these locations
to  bring greater focus on their respective served markets  and
accelerate  new  product  development.   The  Company's   major
manufacturing  and  engineering facilities  and  administrative
offices are located in six company-owned buildings, aggregating
281,000  square  feet, on its 33 acre site in Tucson,  Arizona.
The  Company  also leases approximately 88,800 square  feet  in
Tucson. All of this leased space is on short term contracts  of
two  years  or  less.  The major single building lease  is  for
61,000  square  feet  and  will  expire  in  March  1999.   The
aggregate  current  gross rental for all Tucson  properties  is
approximately  $576,000  per  year.  The  Company   also   owns
approximately 120 acres of land in Tucson which is  being  held
in reserve for future expansion.

In December 1998, the Company's Scottish subsidiary purchased a
12,000  square  foot  building in  Livingston,  Scotland  which
houses  product  development and administrative  offices.   The
Scottish subsidiary also owns approximately 20 acres of land in
Livingston, Scotland. The Company's Atsugi Technical Center  in
Atsugi,  Japan, is a 44,500 square foot building  which  houses
sales,   product   testing,   and  research   and   development
activities;  the  Company  has a fifteen  year  lease  on  this

<PAGE> 11

facility  which  expires in 2001. Also, the Company  has  other
various  sales  offices that lease space under agreements  with
varying maturities.

The  Company's  Tucson, Arizona campus is part  of  the  Tucson
International Airport Superfund site.  The Company  has  agreed
with the United States Environmental Protection Agency (EPA) to
implement  site remediation actions pursuant to the  provisions
of  a  Consent  Decree  Agreement with the  EPA.   The  Company
incurred  approximately  $75,000,  $200,000,  and  $149,000  of
remediation expense in 1998, 1997, and 1996, respectively.

ITEM 3.  LEGAL PROCEEDINGS
The  Company is from time to time involved in legal proceedings
of  a  character  normally incident to its business,  including

TO OUR SHAREHOLDERS:

Burr-Brown  achieved good performance during 1998, despite  the
difficult   business   conditions   that   prevailed   in   the
semiconductor  industry for most of the year.  For  the  fourth
consecutive  year, we set new company records for profitability
and  the number of new products brought to market. As evidenced
by design wins, our products introduced during the last several
years  have  been  very well received by our  customers.  As  a
result,  we  now  participate broadly in many of  today's  most
exciting  and  rapidly developing markets. Consequently,  Burr-
Brown enters 1999 poised to take advantage of rapidly expanding
opportunities  for  high performance analog  and  mixed  signal
integrated circuits.

FINANCIAL PERFORMANCE:

The  Company's 1998 revenue was $258.1 million and  net  income
was   a  record  $35.9  million.  As  compared  to  1997,  this
represented  a  9.8% increase in profit on  revenue  growth  of
2.4%.  The improvements in gross margin and reduction in sales,
marketing,  general and administrative expense demonstrate  the
increased operating efficiencies that we were able to  achieve.
These  improvements not only increased profit but also  allowed
us to increase investment in research and development by nearly
18%.  The Company's financial position also strengthened during
1998.  Cash  and equivalents increased by 21.4%  to  over  $120
million, and stockholders' equity increased by 16.4% to  $273.5
million.

NEW PRODUCTS:

Our  new  product program continued to gain momentum  in  1998,
with  a  record  87  new  products introduced.  Many  of  these
products  are standard linear integrated circuits (SLICs)  that
are used for a broad array of applications by diverse customers
in   many  markets.  An  increasing  number  of  products   are
application  specific  standard products (ASSPs)  which  target
large  and rapidly emerging applications within communications,
consumer,  industrial and computing markets.  Examples  include
highly integrated ASSPs developed for broadband communications,
CT  scanners,  digital camcorders, digital  still  cameras  and
scanners.  In  many  instances, these  products  represent  the
enabling  technologies in terms of both  cost  and  performance
that make our customers' products economically viable. The more
effectively  we  can meet our customers' cost  and  performance
requirements, the more elastic these markets become, leading to
greater growth opportunities.  New products introduced in the 
past five years are now the source of half of our annual revenue.
We firmly believe that this demonstrates the continued success
of our strategy to bring high performance products to high
volume signal processing applications.

MARKETS FOCUS:

1998 marked the first year that more than half of the Company's
revenue  was  derived  from  its newer  served  communications,
consumer and computing markets. Revenue from the communications
market,  where  we  have established significant  positions  in
wireline  and wireless applications, grew by more than  25%  in
1998  and  now  accounts  for nearly a quarter  of  our  sales.
Another  quarter  now  comes from the  consumer  and  computing
markets. At the same time, we plan to continue to emphasize the
industrial market, which presents us with a stable, diverse and
profitable  business. As a whole, we intend to  approach  these
markets  in  a synergistic and diversified manner, taking  full
advantage  of  the  expertise that we  have  developed  in  our
traditional  markets to address the needs  of  today's  rapidly
emerging  markets.  We believe this to  be  the  best  path  to
accelerate both growth and profitability.

The  following table represents a graph which has been  omitted
for the electronic filing.

                         1998 Revenue by Market
                         ----------------------
Communications                     23%
Computing                          05%
Digital Audio/Video                25%
Industrial                         47%

OUTLOOK:

We  expect  that industry conditions will improve in  1999  and
that  we are ready to take great advantage of that improvement.
Improved  market conditions will enable us to set  new  company
records  for  financial  performance, new  product  output  and
design  wins  in  the coming year. We firmly believe  that  the
analog  IC business is a good place to be and that our strategy
and execution of the recent years has positioned us well within
it.

We  thank you, our shareholders, for your continued support. We
remain committed to maximizing the value of your investment  in
Burr-Brown.

ANALOG IS THE PLACE TO BE:

The   world   we   comprehend  is  analog.   Sound,   pressure,
temperature....all physical phenomena and sensations are analog in
nature. As the costs of computing and data storage plummet,  it
is  becoming  more  economically viable to use  digital  signal
processing (DSP) to measure and control the analog world around
us.  In  order  to do so, the real-world signal must  first  be
converted  from  the analog to the digital domain.   Therefore,
the digital revolution fuels an analog revolution. The need for
linking  the  two  domains---analog  and  digital---real   and
mathematical---expands in lockstep.

What  key  product areas do analog and mixed-signal  integrated
circuits (ICs) fulfill? The input and output devices connecting
electronic systems to the physical world demand a huge  variety
of  amplifiers,  signal isolation barriers,  and  power  output
devices.  The  control of the power that drives  these  systems
demands analog solutions in the form of regulators, converters,
and references. And, conversion of digital signals into and out
of the analog domain drives a rapidly growing demand for Analog-
to-Digital (A/D) and Digital-to-Analog (D/A) converters of  all
types. Burr-Brown products compete in all these areas and more.

Optimizing the interface between digital and analog signals  in
an  electronic  system can be a critical  factor  in  achieving
breakthrough performance. In many cases, moving that interface
to an analog chip can be of great value to the system designer.
Our  mixed-signal  design and process capabilities  extend  our
ability to include digital circuit functions on-board our
products and increases the value provided to the customer.

Although  digital and analog companies share  the  same  growth
drivers,  the  business models are markedly  different.  Analog
products tend to have longer life cycles and more stable
pricing.  Product  diversity creates  a  unique  analog  design
requirement for specialized engineering talent which serves  as
a sustainable barrier to entry by competitors.

As  electronic  signal processing becomes more  pervasive,  the
need  for  fast, accurate, and less expensive ways for  getting
signals to, and from, the physical world grows accordingly.
This is the unique opportunity for analog technology...This  is
the place to be...This is where you will find Burr-Brown.

TRADITIONAL AND EMERGING MARKETS:

Traditionally, the definition of our products and the  majority
of our revenue came from industrial markets---industrial control,
process  control, test, and instrumentation. And although  this
market  has  been  stable in its growth, our  high  performance
analog  and  mixed-signal  technology  has  become  a  critical
complement to digital signal processing (DSP) in opening  up  a
new  range  of high growth applications.  Within the last  five
years,  we  have  rebalanced  our  market  strategies  from   a
dependency on industrial applications for the majority  of  our
revenue, to a majority of revenue derived from emerging  growth
markets.

In  communications, computing, and consumer audio  applications
we  have  been  able  to  target  OEM  customers  that  require
performance  analog  and  mixed-signal  ICs  in  high   volume.
Targeted  applications in these markets  push  the  performance
limits of linear ICs in all dimensions: high precision, package
size, power dissipation, functionality, speed---and  price.  By
filling  these  unique sockets, Burr-Brown is positioned  as  a
strategic  supplier with enabling technologies  that  help  our
customers create and expand their markets.

For example, our recently introduced low cost, high performance
operational  amplifiers have been designed into several  brands
of next-generation cellular handsets. Similarly, our new line
of  single-chip  video  signal processing  products,  with  the
capability   to   condition  and  convert  low  level   signals
transmitted  directly from a CCD imaging chip and operate  from
three  volts,  have  been well received for  a  wide  range  of
consumer applications from camcorders to digital still cameras.
A third example of extending our product development activities
into emerging markets is the introduction of specialized mixed-
signal  audio products that meet the standards of  the  Digital
Versatile Disc (DVD) market.

Our   plan   is  to  broaden  our  presence  in  all   of   our
markets---industrial, communications, consumer, and computing. We
will continue our strategy of providing a wide selection of
standard  high performance ICs that serve tens of thousands  of
customers worldwide, while at the same time we are accelerating
our efforts in growth markets by developing application
specific products which will create large volume opportunities.

Communications,  computing,  and consumer  audio  are  emerging
markets. For example, the worldwide market for digital  cameras
is projected to grow significantly for the next several years.

APPLICATION SPECIFIC STANDARD PRODUCTS:

Consistent  with  our strategy to increase our  focus  on  high
growth   markets,  our  product  development   efforts   target
Application Specific Standard Products (ASSPs).  We  work  with
key customers to design products that are targeted for a unique
application  or industry standard, but unlike custom  products,
can be used by all customers in that specific application.

From  our point of view, ASSPs have the advantage of rapid ramp
up  to  production volume as the product is predefined  to  the
system  designer's  needs. This significantly  streamlines  the
customer's design and development process. The customer usually
achieves  breakthrough performance and cost for his product  by
using  an  ASSP that may not have been possible using  standard
catalog  products. Furthermore, the customer usually  considers
the  development  of an ASSP to be a strategic partnership  and
will only collaborate with a few select suppliers.

As  an example, we have developed application specific products
for  digital subscriber line (xDSL) technology---a high data rate
transfer  system  using  the  copper  wiring  in  the  existing
telephone  system  infrastructure.  One  implementation,  HDSL,
currently  provides the most cost effective way  for  telephone
companies  to  provide  high speed data  transfer  to  business
customers. Soon HDSL's evolutionary cousin, ADSL, will  provide
even  higher  performance  levels of  digital  service  at  the
consumer  level. Our ASSPs provide the telephone  line  driving
and receiving capability, as well as the data conversion needed
to  transform  the  signal to and from the digital  domain  for
processing.

Another recently developed ASSP is a data converter designed as
a  touch  screen  controller  for Personal  Digital  Assistants
(PDAs)  and  other  touch  screen  applications.  This  product
provides, in a single chip, the circuitry required for a  touch
screen interface, including drivers. The converter controls the
analog  screen sensing and provides a digital code to  the  CPU
defining the "touched" screen location.

In  the  past four years, the contribution of ASSP products  to
sales  revenue has increased by more than 50%, and  we  are  on
course for having standard products and ASSPs contribute
equally to our revenue within five years.

The  Digital  Subscriber Line (DSL) market is  emerging.   This
technology utilizes existing copper telephone wires to transmit
internet  data  at  rates up to 40 times  faster  than  current

December 31, 1998

ACCOUNTING POLICIES

ORGANIZATION:  Burr-Brown Corporation  develops,  manufactures,
and  markets electronic components including precision  linear,
data  conversion, and mixed signal integrated  circuits.  These
products  address  applications for  both  analog  and  digital
signal  processing relating to communications,  industrial  and
process control, test and measurement, medical instrumentation,
digital  audio,  multimedia,  imaging,  and  personal  computer
systems. Principal markets for these products are North America
(principally  the United States), Europe (Germany,  the  United
Kingdom, and elsewhere), and Asia (principally Japan). Revenue
from these applications in these markets can be volatile and is
dependent on general economic conditions.

USE  OF  ESTIMATES: The preparation of financial statements  in
conformity   with  generally  accepted  accounting   principles
requires  management  to make estimates  and  assumptions  that
affect  the  amounts reported in the financial  statements  and
accompanying  notes.  Actual results could  differ  from  those
estimates.

PRINCIPLES   OF   CONSOLIDATION:  The  consolidated   financial
statements  include the accounts of Burr-Brown Corporation  and
its majority owned subsidiaries (the Company), of which all but
one  are  wholly-owned. Investments in which  ownership  is  at
least  20% but not over 50% are accounted for under the  equity
method.  Other  investments are accounted for  using  the  cost
method.  All significant intercompany accounts and transactions
are eliminated.

INVENTORIES: Inventories are valued at the lower of cost (first-
in, first-out basis) or market.

LAND,  BUILDINGS, AND EQUIPMENT: Land, buildings, and equipment
are stated at cost. Depreciation on buildings and equipment  is
computed by the straight-line method over the estimated  useful
lives ranging from three to forty years.

REVENUE RECOGNITION: A portion of the Company's revenue is from
sales  made  to  domestic distributors under  agreements  which
provide for certain price protection and limited product return
privileges. As a result, the Company defers recognition of  the
gross profit on such sales until the merchandise is sold by the
distributors. All other sales are recognized when  the  product
is shipped, with appropriate provision for sales returns.

INCOME  TAXES:  Income  taxes  are  determined  utilizing   the
liability method. This method gives consideration to the future
tax  consequences associated with temporary differences between
the  carrying  amounts of assets and liabilities for  financial
statement  purposes  and  the  amounts  used  for  income   tax
purposes.

FOREIGN  CURRENCY  TRANSLATION:  The  financial  statements  of
foreign  subsidiaries have been translated in  accordance  with
Statement  of  Financial Accounting Standards  (SFAS)  No.  52,
FOREIGN  CURRENCY TRANSLATION. The gains and losses  resulting
from  the change in exchange rates from year to year have  been
included  as  a  component of accumulated  other  comprehensive
income. Transaction gains and losses, which are not significant
for all years presented, are currently reflected in income.

CONCENTRATION OF CREDIT RISK: Financial instruments which could
potentially subject the Company to significant concentrations
of  credit risk consist principally of cash equivalents, short-
term investments, long-term investments, trade receivables, and
foreign currency contracts.

The  Company  maintains  cash and cash equivalents  at  various
financial   institutions.  These  financial  institutions   are
located throughout the world, and Company policy is designed to
limit  exposure at any one institution and takes  into  account
the   relative  credit  standing  of  these  institutions.  The
Company's  short-term and long-term investments  are  purchased
through high credit quality financial institutions. The cost of
these  investments approximated their fair value at 1996  year-
end,  while fair value exceeded cost by $319 and $278  at  1997
and   1998  year-end,  respectively  (see  note  entitled  Cash
Equivalents and Investments).

Credit risk with respect to trade receivables is limited due to
the  large number of entities comprising the Company's customer
base  and  their  dispersion across many different  industries.
Furthermore,  management  continually  monitors   and   adjusts
allowances associated with these receivables.

Credit  risk  with  respect to foreign  currency  contracts  is
mitigated  by maintaining relationships with major  U.S.  banks
and  arranging  foreign  currency hedging  products  with  such
banks.  The fair value of foreign currency contracts was ($244)
at  December  31,  1998  (see  note entitled  Foreign  Currency
Contracts and Hedging Activities).

In   1997,  sales  to  a  domestic  distributor  accounted  for
approximately 10% of consolidated net revenues. There  were  no
sales to a single distributor or customer that exceeded 10%  of
consolidated net revenues in 1998 or 1996.

ACCOUNTING POLICIES (continued)

STOCK  ISSUED  TO  EMPLOYEES:  Stock  options  are  granted  to
employees  under  the Company's Stock Incentive  Plan  with  an
exercise price equal to the fair value of the shares at date of
grant.  The  Company  accounts  for  stock  option  grants   in
accordance  with  Accounting Principles Board Opinion  No.  25,
ACCOUNTING FOR STOCK ISSUED TO EMPLOYEES, and  accordingly,  
recognizes no compensation expense for the stock option grants.

EARNINGS PER SHARE: In 1997, the Financial Accounting Standards
Board  issued  SFAS No. 128, EARNINGS PER SHARE.  SFAS  No. 128
replaced  the calculation of primary and fully diluted earnings
per  share  with basic and diluted earnings per share.   Unlike
primary  earnings per share, basic earnings per share  excludes
any  dilutive  effects  of options, warrants,  and  convertible
securities. Diluted earnings per share is very similar  to  the
previously  computed  fully diluted earnings  per  share.   All
earnings per share amounts for all periods have been presented,
and  where  appropriate, restated to conform to  SFAS  No.  128
requirements.  References to share and per share  amounts  have
been  restated to reflect a three-for-two stock split effective
April,  1997, as well as a three-for-two stock split  effective
March, 1998.

ACCUMULATED OTHER COMPREHENSIVE INCOME: As of January 1,  1998,
the  Company  adopted  SFAS  No. 130,  REPORTING COMPREHENSIVE
INCOME.  SFAS  No. 130 establishes new rules for the  reporting
and   display  of  comprehensive  income  and  its  components;
however,  the  adoption of SFAS No. 130 had no  impact  on  the
Company's   consolidated  results  of   operations,   financial
position,  stockholders' equity or cash  flows.  SFAS  No.  130
requires   foreign   currency   translation   adjustments   and
unrealized  gains  or  losses on investments,  which  prior  to
adoption  were reported separately in stockholders' equity,  as
well  as  unrealized gains or losses on cash flow  hedges  upon
adoption of SFAS No. 133, to be included in other comprehensive
income.  Prior year financial statements have been reclassified
to  conform  to  the requirements of SFAS No. 130.  Accumulated
other comprehensive income consists of the following:

IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS: In March  1998,
the AICPA issued SOP 98-1, ACCOUNTING FOR THE COSTS OF COMPUTER
SOFTWARE  DEVELOPED FOR  OR  OBTAINED  FOR  INTERNAL USE.  The
Company adopted the SOP on January 1, 1999. The  SOP  requires
the capitalization of certain costs incurred after the date  of
adoption  in  connection with developing or obtaining  software
for  internal  use.  As the Company already  has  a  policy  of
capitalizing  internal  use  software,  the  Company  does  not
believe  that  the adoption of this SOP will  have  a  material
effect  on the Company's consolidated results of operations  or
financial position.

CASH EQUIVALENTS AND INVESTMENTS
The  Company  classifies its investments as  cash  equivalents,
short-term,  or long-term investments based on  the  number  of
days between the purchase date and the original maturity dates,
reset  dates,  or  call  dates of its investments.  Investments
classified as cash equivalents have a range of days from  1  to
90 days, short-term investments have a range of days from 91 to
365  days, and long-term investments have a range of days  over
365  days. At December 31, 1998, the Company had no investments
maturing after December 1, 2000.

The  fair value of cash equivalents and investments at December
31,  1998,  1997, and 1996, classified as available  for  sale,
consisted of:

</TABLE>

Fair  value exceeded cost by $278 and $319 at December 31, 1998
and  1997,  respectively, while approximating cost at  December
31,  1996.  The unrealized gain at December 31, 1998 and  1997,
net  of  tax,  is reported as a component of accumulated  other
comprehensive  income.  Fair  value  for  such  securities   is
determined based on quoted market price.

Income   received   from  cash  equivalents   and   investments
(classified as other income) was $4,432, $3,624, and $3,740, in
1998, 1997, and 1996, respectively.

FOREIGN CURRENCY CONTRACTS AND HEDGING ACTIVITIES

Due  to the Company's significant international sales, both  to
unafilliated  customers  and to its foreign  subsidiaries,  the
Company  is  exposed  to  the effect of foreign  exchange  rate
fluctuations  on the future U.S. dollar value of its  sales  as
well  as  the  U.S.  dollar  value of its  accounts  receivable
denominated  in foreign currencies. For currencies  other  than
the  Japanese  yen, the Company mainly uses the natural  hedges
resulting  from intercompany payables and expenses incurred  in
local  currencies  to  dampen the effect  of  foreign  currency
fluctuations.  Due  to  the  significance  of  Japan   to   its
consolidated  operations,  the Company  uses  foreign  currency
contracts  to  hedge  forecasted  sales  transactions   against
foreign  currency fluctuations. The Company from time  to  time
may  also  use  foreign  currency forward  contracts  to  hedge
accounts receivable denominated in Japanese yen.

The  Company  adopted SFAS No. 133, ACCOUNTING  FOR DERIVATIVE
INSTRUMENTS AND HEDGING ACTIVITIES, as of October 4, 1998,  the
first  day of its fourth fiscal quarter in 1998. There  was  no
impact  on  consolidated income or on consolidated  accumulated
other  comprehensive  income from adopting  SFAS  No.  133.  At
December  31,  1998,  all  of  the Company's  foreign  currency
contracts   were   designated  as  cash  flow  hedges   against
forecasted  sales  to  the Company's Japanese  subsidiary.  The
Company  assesses  the  effectiveness of its  foreign  currency
forward  contracts using the spot rate, and  views  the  option
premium  as the inherently ineffective portion of their foreign
currency   purchased  option  contracts.  The   ineffectiveness
resulting  from  such contracts is reflected  in  other  income
(expense)  and  was immaterial to 1998 operations.  The  losses
deferred as other comprehensive income amounted to $151 net  of
the  deferred tax effect of $93. Such amounts will be reflected
in  the income statement between January and June, 1999, as the
forecasted transactions occur.

The  following  table  presents the gross notional  amounts  of
these foreign currency contracts and their fair value (based on
prices  or forward rates quoted by dealers) as of December  31,
1998:

Prior  to adopting SFAS No. 133, the Company marked all foreign
currency forward contracts which hedged accounts receivable to
market,  with  the  resulting gain or loss  included  as  other
income (expense). Gains under foreign currency purchased option
contracts  which  were designated and effective  as  hedges  of
forecasted sales transactions were deferred until realized,  at
which  time  they were reported as revenue in the  consolidated
financial  statements. Such realized and unrealized  gains  and
losses are insignificant for all periods presented.

NOTES PAYABLE

The  Company  has  available short-term  credit  facilities  of
approximately $31,276 with $17,289 outstanding as  of  December
31,  1998.  There are no compensating balance requirements. All
of  the  available short-term credit facilities are in  foreign
currencies  and  are  used  to support  the  Company's  foreign
operations. Interest rates are tied to prevailing national base
rates, and the weighted-average rates for 1998, 1997, and  1996
were   1.6%,   1.7%,  and  3.3%,  respectively.  These   credit
facilities are renewable annually at various dates.

The  Company has a $10 million revolving line of credit with  a
major U.S. bank. The Company can borrow at LIBOR + 1.25% or the
bank's  Prime  rate or the bank's "bid rate." The  Company  may
select  terms of 30, 60, 90, and 120 days for LIBOR borrowings.
The  revolving line of credit carries an annual commitment  fee
of 1/4 % on the unused portion of the commitment. The loan
agreement  has  current ratio and net worth  covenants.  As  of
December  31,  1998,  the  Company is in  compliance  with  all
covenants  and conditions contained in the loan agreement.  The
loan  agreement  does  not require compensating  balances.  The
Company's revolving line of credit terminates at May 5, 2000.

Under   the   various  long-term  debt  agreements   consisting
exclusively  of  capital  lease  obligations,  the  Company  is
obligated  to pay the following principal amounts for  each  of
the next five years:

INCOME TAXES (CONTINUED)
Actual  current  tax  liabilities are lower  than  the  amounts
reflected  above by the tax benefit from stock option  activity
of   $3,445,  $2,576,  and  $155  in  1998,  1997,  and   1996,
respectively.  The  tax benefit from stock option  activity  is
recorded as a reduction in current income taxes payable and  an
increase in additional paid-in capital.

Deferred  income taxes reflect the net tax effects of temporary
differences  between  the  carrying  amounts  of   assets   and
liabilities  for financial reporting purposes and  the  amounts
used  for  income tax purposes. Significant components  of  the
Company's deferred tax liabilities and assets are as follows:

At  December  31,  1998,  and December  31,  1997  the  Company
recorded  valuation allowances to reflect the estimated  amount
of  deferred tax assets which may not be realized from  foreign
loss  and  tax  credit  carryforwards. At  December  31,  1996,
valuation  allowances  were recorded  to  offset  deferred  tax
assets  which could only be realized by earning taxable  income
in  future  years.  At  that time, management  established  the
valuation allowances because it could not be assured that  such
income would be earned.

Undistributed earnings of foreign subsidiaries were $16,457  at
December 31, 1998. No provision for U.S. tax has been  made  on
these  undistributed  earnings  as  they  are  intended  to  be
permanently  reinvested or will be remitted substantially  free
of additional tax.

A  foreign subsidiary has a net operating loss carryforward  of
$330,  which  can be carried forward indefinitely. The  Company
has  federal and state tax credit carryforwards totaling $6,408
which expire at various dates beginning in 2003.

Net  income taxes paid amounted to $9,995, $5,773, and  $12,987
in 1998, 1997, and 1996, respectively.

STOCKHOLDERS' EQUITY-Share amounts in thousands

The  Company adopted an Incentive Stock Plan in 1981 which  was
amended  and  restated in 1983. Under this plan,  options  were
granted  to  key  employees, subject to certain limitations  to
purchase  an aggregate of 3,167 shares of common stock  at  not
less  than the fair market value on the date of the grant.  All
options under the plan must be exercised within ten years  from
the  date  of  the  grant. This plan expired in  1993,  and  no
further  options will be granted under this plan. However,  all
options outstanding under this plan will continue to have  full
force and effect in accordance with their terms.

In  1993,  the  Company adopted the 1993 Stock Incentive  Plan.
This  plan  is intended to benefit the Company by providing  an
incentive to certain key employees, directors, and consultants.
The  aggregate number of shares which may be issued under  this
plan  shall  not  exceed 8,888 shares, including  1,614  shares
available  from the 1981 Plan. This plan is administered  by  a
committee  of  the  Board of Directors.  The option  price  per
share  shall  be fixed by the committee, but in no event  shall
the  option price per share be less than the fair market  value
on  the  date  of the grant. The committee also determines  the
date on which granted options will become exercisable, although
all  options under this plan must be exercised within ten years
from the date of grant.

As  of  December,  1998, the Company had a  plan  in  place  to
purchase  up to 3,000 shares of the Company's common  stock  in
the  open  market. The acquired shares will be used to  provide
shares  for  the  employee  stock  option  and  stock  purchase
programs.

On  August  2,  1998, the Company initiated an  employee  stock
purchase  plan  (the  "Purchase  Plan")  that  allows  for  the
purchase  of common stock every six months at 85% of  the  fair
market  value  at  the  date of grant  or  the  exercise  date,
whichever  value is less. The Purchase Plan is qualified  under
Section  423  of the Internal Revenue Code. All of the  600,000
shares  authorized under the Purchase Plan were  available  for
issuance at December 31, 1998.

Pro  forma  information regarding net income and  earnings  per
share is required by SFAS No. 123, ACCOUNTING FOR STOCK-BASED
COMPENSATION,  and has been determined as if  the  Company  had
accounted  for its employee stock options under the fair  value
method of that Statement. The fair value for these options  was
estimated  at  the  date of grant using a Black-Scholes  option
pricing  model with the following assumptions for  1998,  1997,
and  1996, respectively: risk-free interest rates ranging  from
4.16%  to  5.76%, 5.90% to 6.93%, and 5.00% to 5.34%;  dividend
yields of 0.0%; volatility factor of the expected market  price
of  the  Company's common stock of 0.608 in 1998, and 0.508  in
1997  and  1996;  and an expected life of an  option  of  seven
years.

The  Black-Scholes option valuation model was developed for use
in  estimating the fair value of traded options which  have  no
vesting  restrictions and are fully transferable. In  addition,
option  valuation models require the input of highly subjective
assumptions  including  the expected  stock  price  volatility.
Because    the   Company's   employee   stock   options    have
characteristics  significantly different from those  of  traded
options,   and   because  changes  in  the   subjective   input
assumptions  can materially affect the fair value estimate,  in
management's  opinion, the existing models do  not  necessarily
provide  a  reliable single measure of the fair  value  of  its
employee stock options.

SFAS  No.  123  requires  the  Company  to  present  pro  forma
disclosures for options granted in 1995 and thereafter. Because
prior  years'  awards were not included in  these  disclosures,
they would not be indicative of future amounts.

For purposes of pro forma disclosures, the estimated fair value
of  the  options  was  amortized to expense  over  the  vesting
period. Pro forma disclosures also include the estimated impact
of the Purchase Plan, which effect was immaterial in 1998.

</TABLE>

During  1989,  the  Board  of  Directors  declared  a  dividend
distribution  of  one  common stock  purchase  right  for  each
outstanding  share of common stock. The rights are  exercisable
only if a person or group acquires 20% or more of the Company's
common stock or announces a tender offer which would result  in
ownership  by  a person or group of 20% or more of  the  common
stock. At that time, a right plus $0.1407 may be exchanged  for
one  one-hundredth share of common stock of the  Company.  Upon
the  acquisition of 40% or more of the Company's  common  stock
(unless  at least 80% is acquired in a cash tender offer),  the
holders of rights (other than the acquirer) will have the right
to  purchase shares of the Company's common stock at  half  its
market  value.  In addition, the rights provide that  upon  the
merger  or  transfer of 50% or more of the  assets  or  earning
power of the Company to a person who has acquired at least  20%
of  the common stock, the holders of rights will have the right
to  purchase shares of the acquirer's common stock at half  its
market value.

The  rights are subject to mandatory redemption for $0.003  per
right  at  the discretion of the Company's Board of  Directors.
All  rights  expire  on  August 9,  1999,  unless  extended  or
redeemed  by  the  Company and do not have dividend  or  voting
privileges while outstanding.

Shares  used  in  the  basic  per share  calculation  represent
weighted-average  shares outstanding in the applicable  period.
The  additional  1,609, 1,881, and 1,507  shares  used  in  the
dilutive   share   calculation  in  1998,   1997,   and   1996,
respectively,  represent the dilutive effect of employee  stock
options. The impact of the Purchase Plan on 1998 diluted shares
was not material.

BUSINESS SEGMENT DATA

The  Company's business is organized on a geographic basis, and
the Company's Chief Operating Decision Maker (the Company's
President and Chief Executive Officer) assesses performance and
allocates resources on this basis. The information provided  in
the following section is representative of the information used
by  the  Chief  Operating Decision Maker  in  deciding  how  to
allocate resources and in assessing performance.

The  Company  has  three  reportable  segments:  North  America
(principally  the  United  States),  Far  Eastern  (principally
Japan,  but including Singapore beginning in 1998) and European
(principally the United Kingdom, France, Germany,  and  Italy).
Each  of  these segments derives revenue from the sale  of  the
full  array  of the Company's product lines, although  the  Far
Eastern  segment  has  a  higher concentration  of  sales  from
certain mixed signal products.

The   Company's   Chief  Operating  Decision  Maker   evaluates
performance and allocates resources based on pretax income. The
accounting policies of the reportable segments are the same  as
those  described  in  the  summary  of  significant  accounting
policies.  Sales  between  business  segments  are   based   on
negotiated prices. The North American business segment includes
corporate  activity that benefits the Company as a  whole.  Net
sales  are  attributed to segments based  on  location  of  the
customer.

EMPLOYEE BENEFIT PLANS

The  Company  has  a  defined  contribution  plan,  the  Future
Investment  Trust  (FIT). The FIT is a 401(k)  salary  deferral
plan  and allows eligible participating U.S. employees to defer
up to 15% of their salaries. Employee contributions are matched
by the Company at a rate of 25% of the employee's contribution.
The  Company's  contributions vest at 25% per year  and  become
fully  vested  to  the employee after four  years  of  service.
Additional voluntary Company contributions may be made  to  FIT
participants' profit sharing accounts.

The  Company has a noncontributory defined benefit pension plan
which covers all eligible U.S. employees and generally provides
benefits to retired employees based on their length of service,
age,  and  a  percentage of qualifying compensation during  the
final  years  of  employment. On January 1,  1998  the  Company
adopted a cash balance feature within the defined benefit plan.
Employees  hired after January 1, 1998 will receive  a  benefit
from  the cash balance account, while employees hired prior  to
January  1,  1998 will receive a benefit from the cash  balance
account or pension formula, whichever is greater. Contributions
are  intended  to provide not only for benefits  attributed  to
service  to date, but also for those expected to be  earned  in
the  future.  The  Company's policy is  to  contribute  amounts
sufficient  to  at  least meet the Employee  Retirement  Income
Security Act's minimum funding requirements.

auditing standards. Those standards require that we plan and
perform  the audit to obtain reasonable assurance about whether
the financial statements are free of material misstatement. An
audit  includes examining, on a test basis, evidence supporting
the  amounts  and disclosures in the financial  statements.  An
audit  also  includes assessing the accounting principles  used
and  significant  estimates  made by  management,  as  well  as
evaluating  the  overall financial statement  presentation.  We
believe  that  our audits provide a reasonable  basis  for  our
opinion.

In  our  opinion,  the financial statements referred  to  above
present  fairly,  in  all material respects,  the  consolidated
financial  position of Burr-Brown Corporation and  Subsidiaries
at  December  31,  1998, 1997, and 1996, and  the  consolidated
results  of their operations and their cash flows for  each  of
the  three  years  in the period ended December  31,  1998,  in
conformity with generally accepted accounting principles.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS

The  following  discussion, including but not  limited  to  the
section entitled "Business Outlook," contains forward-looking
statements which involve risks and uncertainties. The Company's
actual results could differ materially from those projected  in
the  forward-looking statements as a result of certain factors,
including  those  set  forth  under "Factors  Affecting  Future
Results" and elsewhere in this Annual Report.

1998 COMPARED TO 1997

The  Company reported 1998 revenue of $258.1 million, which was
2.4%   above  1997  revenue.  Due  to  the  difficult  industry
conditions which prevailed for most of 1998, quarterly revenues
declined  sequentially through the third quarter  and  remained
relatively flat in the fourth quarter. Revenue in the U.S.  and
Europe  increased from the prior year, while revenue from  Asia
declined.   Sales  into  the  Southeast  Asian  (SEA)   region,
excluding  Japan, decreased marginally reflecting  the  current
economic climate in the region. A weakening Yen caused  revenue
from  Japan  to  decline.  In  1998,  revenue  from  the  newer
communication, high performance consumer, and computing markets
accounted for 53% of the Company's total revenue; for the first
time exceeding revenue from the industrial market. Revenue from
both  the  communications and digital audio and  video  markets
increased  from  last year both in absolute dollars  and  as  a
proportion  of  total  Company revenue. As  compared  to  1997,
communications  market  revenue grew  by  more  than  25%.  The
industrial  market,  in which the Company  maintains  a  strong
position,  accounted  for  47% of  total  revenue.  It  is  the
Company's strategic intent to expand its participation in these
traditional  markets while increasing its  penetration  of  the
higher volume and faster growing communications, consumer,  and
computer markets.

Gross Margin improved to 51.4% compared to 50.4% in 1997.  This
improvement  reflected  a  higher  level  of  internal  factory
utilization  and  increased operating leverage  resulting  from
higher production levels. Mix continues to shift toward
higher  volume  products  with  lower  average  selling  prices
without  having  an adverse effect on aggregate  gross  margin.
This  is  consistent with the Company's strategy to offer  high
performance  analog  and mixed signal integrated  circuits  for
high  volume,  fast growing, emerging applications.  Consistent
with   past   experience,  like-product,  like-volume   pricing
remained  stable. Favorable foundry wafer pricing  allowed  the
Company to participate in higher volume applications without a
negative  impact on gross margin. The Company believes  it  can
significantly  expand internal wafer fabrication capacity  with
relatively  modest  capital investments in  certain  bottleneck
equipment.  The Company believes it has sufficient  commitments
for  external  wafer  foundry capacity to  meet  its  near-term
requirements.  Assembly  and test  capacity  will  be  expanded
throughout 1999 to the extent required by volume increases.

Operating expenses for the year increased to $88.0 million from
$83.5 million in 1997. Overall operating expenses increased  as
a  percentage of revenue to 34.1% from 33.1%. Spending  in  the
Sales,  Marketing, General and Administrative expenses  (SMG&A)
decreased  to  18.6% of revenue from 19.6%. This  reflects  the
Company's  continuing  efforts to drive toward  a  lower  model
level  for  SMG&A expenses. Spending for Research & Development
(R&D) increased as a percentage of revenue to 15.5% from 13.5%.
The  Company  believes  that its continued  commitment  to  R&D
should result in significantly increased product revenue  over
the long run.

Investment in R&D expense increased by $5.9 million or 17.5% to
$39.9  million. A record 87 new products were introduced during
the year; the fourth consecutive year in which a new record was
established.  Nearly  half of the Company's  1998  revenue  was
derived from new products introduced in the last 5 years.  This
is  consistent with 1997, but up 20% over 1996 and  nearly  70%
higher  than  1995. A prime focus of the Company's new  product
program  is  to  offer  highly integrated application  specific
standard  products (ASSPs) that target large  and  fast-growing
markets such as broad-band and wireless communications, digital
audio  and  video,  medical imaging  and  motor  control.  Much
progress  was made on the development of advanced manufacturing
processes   including   the   next  generation   analog   wafer
fabrication  processes.  R&D spending was 15.5% of  revenue  in
1998.  The  Company intends to maintain a similar level  during
1999.

<PAGE> 27

SMG&A  expenses declined to $48.1 million or 18.6%  of  revenue
from  $49.5 million or 19.6% in 1997. This improvement was  the
result   of   consolidation   of   selling,   logistics,    and
administration  activity in Europe and Japan, expanded  use  of
third  party  distribution in all regions and  improvements  in
administrative  efficiency. The Company's long  term  objective
for  SMG&A  is  18%  of  revenue.  In  order  to  support  this
objective,  the  Company  is  continuing  to  consolidate   all
administrative,  logistics, and inventory  functions  in  three
regional  service centers worldwide. The adoption of  a  common
worldwide information system is also expected to further reduce
administrative costs. Worldwide implementation of  this  system
was  completed in 1998 when our Asian operations went  on-line.
The Company's plan anticipates an increase in the proportion of
large  order  opportunities inherent in the strategy  to  bring
high   performance  to  high  volume  applications  which,   if
successful  should  also reduce overall cost  of  selling.  The
increased use of third-party distribution channels has not only
increased   revenue,  but  has  also  reduced  selling   costs.
Approximately half of the Company's 1998 revenues were  derived
from  this  channel, up from 46% in 1997 and 40% in  1996.  The
Company  intends to continue cost restraints and, as a  result,
to maintain SMG&A expenses at approximately 17.0% for 1999.

During 1998, the Company was able to increase its investment in
R&D  by  approximately $6 million while reducing SMG&A spending
by  $1.4  million.  This  reflects  a  continuing  strategy  to
maintain  a substantial level of R&D investment as the  primary
driver  of future revenue growth while reducing SMG&A  expenses
to more competitive levels.

The Company reported 1998 operating income of $44.7 million  or
17.3%  of  revenue, an increase from $43.6 million in 1997.  As
compared  to  1997,  the Company was able to improve  operating
income by 2.5% while devoting 17.5% more resources to R&D.

Other  income  and expense consists primarily of  net  interest
income on invested cash and gains and losses on foreign
currency transactions.

The  1998 tax rate was 26%, down from 30% in 1997. The decrease
was  due  to  an  increased foreign sales corporation  benefit,
increased  tax  credits,  a further  shift  to  tax  advantaged
investments  and favorable Arizona legislation.  The  1998  tax
rate  was less than the U.S. federal statutory tax rate of  35%
due  mainly  to the benefits from a foreign sales  corporation,
research  and  development credits, and tax  exempt  investment
income. At December 31, 1998, based on previous taxable  income
and  projections for future taxable income, management believes
that   with   the   exception  of  foreign  loss   and   credit
carryforwards,  for  which  valuation  allowances   have   been
provided, it is more likely than not that the Company will earn
sufficient  taxable  income  in future  years  to  realize  the
recorded deferred tax assets.

Net income for the year of $35.9 million was the highest in the
Company's history. Net income was up $3.2 million or 9.8%  over
1997.  Net  income represented 13.9% of revenue as compared  to
13.0%  in  1997. Diluted earnings per share (EPS)was  $.94  for
1998, 9.3% higher than the $.86 of 1997.

1997 COMPARED TO 1996

The  Company reported 1997 revenue of $252.1 million, which was
14.6%  above 1996 revenue. All geographic regions were up  over
last  year.  The  U.S.  and  southeast  Asia  showed  the  most
strength.  Domestic  sales increased significantly,  led  by  a
strong  distribution  channel. Sales into the  southeast  Asian
(SEA)  region excluding Japan more than doubled. Japan's growth
was  impacted  by  a  weakening  Yen.  Revenue  from  both  the
communications and digital audio and video markets  contributed
a  larger  proportion of the Company's total  revenue.  Revenue
from  the  communications  market had  the  highest  percentage
increase  when  compared  to 1996. The  percentage  of  revenue
derived  from the digital audio and video and computer  markets
also increased over 1996 levels. Industrial and process control
and  test  and instrumentation, a market in which  the  Company
maintains  a very strong position, accounted for slightly  less
than one-half of total revenues.

<PAGE> 28

At  50.4%  of revenue, gross margin for the year was even  with
1996. Gross margin improved to 51% of revenue during the fourth
quarter  of 1997, reflecting a higher level of internal factory
utilization and increased operating leverage from higher  total
sales.  Mix  continues to shift toward higher  volume  products
with  lower  average selling prices without having  an  adverse
effect  on  aggregate gross margin. Fourth quarter  unit  sales
volume increased by 23% sequentially and by 75% over the fourth
quarter  of 1996. Consistent with past experience, like product
pricing  remained  stable.  Reliance  upon  externally  sourced
wafers inhibited further gross margin expansion.

Operating expenses for the year increased to $83.5 million from
$80.7  million in 1996 but declined as a percentage of  revenue
to  33.1%  from 36.7%. The reduction in this ratio was realized
exclusively in SMG&A.

Investment in R&D expense was increased by $5.5 million or  19%
to $34 million. A record 79 new products were introduced during
the  year; the third consecutive year in which a new record was
established.  Nearly  half of the Company's  1997  revenue  was
derived  from new products introduced in the last 5  years,  up
20% over 1996 and nearly 70% higher than 1995.

SMG&A  expenses declined to $49.5 million or 19.6%  of  revenue
from $52.2 million or 23.7% in 1996. SMG&A expense declined  to
17.6%  of  revenue  during the fourth quarter  of  1997.  These
improvements  were  the  result of  consolidation  of  selling,
logistics, and administration activity in Europe, expanded  use
of  third party distribution in all regions and improvements in
administrative efficiency.

During 1997, the Company was able to increase its investment in
R&D by more than $5 million while reducing SMG&A spending by $3
million.

The Company reported 1997 operating income of $43.6 million  or
17.3% of revenue, a significant increase from $30.1 million  or
13.7%  of  revenue  in 1996. Operating income  for  the  fourth
quarter  of  1997 set a new quarterly record both  in  absolute
dollars  and  as  a  percent  of  sales.  This  improvement  is
primarily due to improved revenue growth and operating  expense
control.  As compared to 1996, the Company was able to  improve
operating  income by 45% while devoting 19% more  resources  to
new product development activities.

Other  income  and expense consists primarily of  net  interest
income on invested cash and gains and losses on foreign
currency transactions. Included in 1996 other income was a $7.2
million gain realized from the sale of a subsidiary in the
first quarter of that year.

The  1997  tax  rate was 30% up from 25.5% in  1996  due  to  a
reduction in tax benefit carryforwards and increased
profitability.

Net  income for the year of $32.7 million was up $3 million  or
10%  over 1996. When excluding a $5.3 million gain realized  in
1996  from  the sale of a subsidiary, net income  increased  by
34.2% on a consolidated revenue gain of 14.6%. Diluted earnings
per share (EPS) was $.86 for 1997, 8.9% higher than the $.79 of
1996. When excluding the $5.3 million or $.14 per diluted share
gain realized from the sale of a subsidiary, 1997 EPS increased
by 32.3%.

LIQUIDITY AND CAPITAL RESOURCES

The Company believes that its financial position as of December
31,  1998  remains  very sound. Despite  over  $26  million  in
capital  spending,  cash,  equivalents,  and  investments  were
$120.3  million  at year end, an increase of $21.2  million  or
21.4% during the year.

Inventories increased by $7.8 million or 17.4% during the  year
to $52.3 million at December 31, 1998. The increase in
inventory  levels from 1997 reflected the Company's  desire  to
run its factories at a higher level than revenue in order to
replenish inventories, especially die bank inventory,  depleted
during  the  capacity constraint difficulties  earlier  in  the
year.

<PAGE> 29

The  Company's expectation for 1999 is for inventory to  remain
relatively flat in absolute terms and, if it is successful in
achieving  sales  growth, to further decline as  a  percent  of
revenue. Currently, annual inventory turns are nearing 2.6 down
from  2.7  at this time last year. The Company's 1999 objective
is  to  improve this to over 3, although its ability to achieve
this  objective  is  subject to several  factors  not  entirely
within the Company's control.

During  the  year, net accounts receivable decreased  by  1.8%.
Days  sales outstanding (DSO) increased to 79 days at  December
31,  1998  from  77  days at the end of  the  prior  year.  The
increase in DSO reflected a higher level of sales in the fourth
quarter  in Japan and non-linearity in monthly shipments.  This
is  planned  to  improve  in  1999  due  to  increased  use  of
distribution, improved shipment linearity, and more  aggressive
collection activity.

Capital  expenditures  totaled $26.5  million  for  1998,  $0.8
million   or   3.3%   higher  than  1997.   Modernization   and
standardization  of manufacturing equipment,  backend  capacity
expansion   due  to  increased  unit  volume,  next  generation
technology development, and development of information  systems
were the primary uses of capital spending. The Company plans to
have  1999 capital expenditures within the range of $20 million
to  $25 million, consisting in large part of capacity expansion
measures and improvements in product design automation.

At  1998  year end, total debt was $21.4 million of which  $4.2
million was term debt. This represented a $9.3 million
increase  in total debt over 1997. Most of this debt  was  held
internationally and represented an interest rate arbitrage
situation in Japan. In addition to term debt, credit facilities
of  approximately  $41.3  million, including  overdraft  credit
facilities  with both domestic and international  banks,  were
available to the Company, of which approximately $17.3  million
or  41.9% was utilized. The current ratio improved to  3.44  in
1998  from 2.95 in 1997. The debt to equity ratio declined year
over  year  from  .05 to .08. 170,000 shares of  the  Company's
common  stock were repurchased in the fourth quarter at a  cost
of   approximately  $3.5  million.  In  October  of  1998,  the
Company's board of directors approved the repurchase of up to 3
million shares of Burr-Brown's common stock, from time to time,
pursuant  to  repurchase guidelines established by  the  Board.
Stockholders' equity increased by $38.6 million or 16.4% during
1998.

The   Company's  balance  sheet  continues  to  be  strong  and
management  believes  that it possesses  more  than  sufficient
capital resources to meet the anticipated requirements  of  the
next twelve months.

International  markets constitute a majority of  the  Company's
revenue. The resulting transactions have exchange rate
fluctuation  risk  associated with them. The  Company  acts  to
minimize the impact of foreign currency exchange rate
transactions through natural hedges afforded by its significant
foreign  operations and through the use of financial hedges  in
the  form  of forward contracts and option contracts.  Exchange
rate  fluctuations  can  also  affect  the  Company's  reported
revenue  as the international subsidiaries' sales are primarily
denominated   in  foreign  currencies  but  reported   in   the
consolidated   financial  statements  in  U.S.  dollars   using
weighted-average   exchange   rates.   (See   also    "Business
Outlook-Market Risk")

The impact of inflation on the Company's financial position and
results of operations has not been significant during the three
year period ended December 31, 1998.

YEAR 2000 ISSUE

YEAR  2000  INITIATIVE: The Year 2000 issue concerns  potential
malfunctions resulting from computer programs using two-digit
year  codes  in  dates instead of four-digit  codes.  This  may
result in hardware and software not functioning properly before
or  following  January  1, 2000, which may  lead  to  minor  or
significant    problems    associated    with    manufacturing,
distribution  and other business operations. Burr-Brown's  Year
2000  initiative  is  being addressed by  a  multi-disciplinary
committee led by senior information system technology managers.
The  committee is evaluating Year 2000 issues in the  following
five key categories:

<PAGE> 30

a. Company products;
b. Business application systems;
c. Information technology ("IT") infrastructure;
d. Non-IT infrastructure (factory and facilities equipment
   and infrastructure); and
e. Third party suppliers and customers.

The  committee is addressing each of these categories in  three
phases:

1. Inventory (identify items with possible Year 2000 risk);
2. Assessment (prioritize the inventory, assess Year 2000
   compliance, plan corrective action and identify initial
   contingency plans); and
3. Remediation (implement corrective action, test and verify
   compliance, execute contingency plans if not compliant).

STATE  OF  READINESS:  The  Company  has  determined  that  its
semiconductor products should not produce errors processing
data as a result of Year 2000 failures, provided that all other
products   (e.g.,  other  software,  hardware  and   electronic
components)  used  with  the Burr-Brown semiconductor  products
properly  exchange  accurate data. The Company's  products  are
used  in  a  wide  variety of applications in conjunction  with
other  electronic components and software from  many  different
vendors;  to  verify proper Year 2000 operation of  a  complete
system, customers will need to verify proper operation of  each
individual  component as well as the system as a whole  in  the
specific application environment.

The  committee  has  completed an  inventory  of  all  domestic
business  application systems and IT infrastructure  (including
software,  hardware and communications infrastructure,  systems
developed   in-house,  purchased  software  and  hardware   and
services  provided  by  third parties).  The  Company  began  a
worldwide replacement of its primary business systems  in  1994
to    provide   additional   significant   information   system
functionality as well as Year 2000 readiness. This  replacement
is  nearly complete and is intended to be completed enterprise-
wide by mid-1999. However, if this replacement is not completed
on  a  timely basis, Year 2000 related failures could adversely
impact  the Company. These primary business application systems
and  IT  infrastructure have been licensed  or  purchased  from
major  software and IT vendors who represent that such  systems
and  equipment  are Year 2000 compliant. In addition  to  those
representations,  the  Company is  internally  assessing  these
systems  to  ensure  Year  2000  compliance  in  the  Company's
application  environment. The committee has identified  certain
non-critical, legacy systems and applications that are  not  or
may  not  be  compliant. Specific compliance  plans  are  being
developed for these and all other items on the inventory. These
plans  include retirement, replacement, renovation, integration
and testing.

The   committee   has   completed  its  inventory   of   Non-IT
infrastructure  and  is currently in the assessment  phase  for
several   critical  systems.  Non-IT  infrastructure   includes
physical  fabrication  and test facilities  and  equipment  for
production.  Burr-Brown's  manufacturing  processes  are   very
automated. The inventory and assessment has identified assembly
and  test equipment that contains embedded proprietary software
or  is  integrated into PC software databases  that  will  need
renovation or replacement. If not remedied, it is possible that
some  of  this infrastructure could cease to function. However,
the Company believes most of this infrastructure would continue
to  function, but may report inaccurate data that could  result
in  production  inefficiencies.  Remediation  plans  are  being
implemented  with  the  assistance  of  the  vendors  of   such
equipment and software.

The Company is formally communicating with significant past and
present  suppliers, customers and subcontractors  to  determine
the extent to which they are vulnerable to Year 2000 issues. To
date, the Company has communicated with approximately 350  such
parties,  and  will continue to communicate with key  suppliers
that  are  not  yet  compliant in an  effort  to  eliminate  or
minimize  any  impact  their non-compliance  may  have  on  the
Company's  operations. Continuing feedback indicates that  most
of  the  Company's  suppliers  do  not  expect  their  business
operations to be interrupted or adversely impacted by Year 2000
problems.  In  the  event  that any significant  customers  and
suppliers  do  not  successfully and timely achieve  Year  2000
compliance, it is possible that the Company's operations  could
be adversely affected.

<PAGE> 31

Burr-Brown   anticipates   completing   its   remediation   and
contingency plans by the end of the third quarter of 1999,  and
intends  to  complete Year 2000 compliance  solutions  for  any
critical  systems that might be earlier impacted by  Year  2000
issues  (e.g.,  order entry systems) prior to  any  anticipated
significant  impact  from  Year 2000 date  issues.  Of  course,
completion of the project is contingent upon the timeliness and
accuracy  of software upgrades and equipment from vendors,  the
adequacy  and  accuracy of our internal and external  resources
used in assessing, remediating and testing our internal systems
for  compliance,  the  timely  cooperation  of  our  suppliers,
subcontractors  and  customers, and  other  potential  factors.
Furthermore, there can be no assurances that implementation  of
the   Company's  Year  2000  initiatives  will  fully  mitigate
potential failures or problems.

COST  OF  COMPLIANCE:  Since 1994,  the  Company  has  expended
approximately $15 million on information system replacement.
The  committee  currently anticipates spending between  $1.0  -
$2.0  million  to  achieve Year 2000 compliance  for  presently
identified  IT  and  Non-IT infrastructure  that  will  require
remediation.  The committee has and will continue  to  use,  as
required, external consultants to assess and mitigate Year 2000
problems. To the extent the Company is required to use  outside
consultants  more  than  presently anticipated,  the  Company's
costs  to  address Year 2000 issues will increase.  These  cost
estimates  may  change as more information becomes  known.  All
Year  2000 costs have been and will continue to be funded  from
operations.

CRITICAL RISKS: Although the Company intends that its Year 2000
initiative will avoid any material adverse effect on its
operations  or  financial condition,  it  recognizes  that  the
occurrence   of   worst   case  Year   2000   scenarios   could
significantly impede its ability to manufacture, distribute and
sell its products for an indefinite period of time. The Company
is dependent on basic public and private infrastructure for its
normal   operations.  In  the  event  utilities,   distribution
channels,  banking  systems or other fundamental  services  are
unavailable as a result of Year 2000 failures, this would  have
a  severe  impact on continuing business operations. Any  long-
term  interruption would have a material adverse impact on  the
Company.  In  addition,  the  Company  does  not  have  readily
available  alternative sources of supply for certain  materials
and  services (e.g., specific wafer production processes).  The
Company  would not be able to replace these critical  suppliers
without significant delay and cost.

IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

In  March 1998, the AICPA issued SOP 98-1, ACCOUNTING  FOR  THE
COSTS  OF  COMPUTER  SOFTWARE DEVELOPED  FOR  OR  OBTAINED  FOR
INTERNAL  USE. The Company adoped the SOP on January  1,  1999.
The SOP requires capitalization of certain costs incurred after
the date of adoption in connection with developing or obtaining
software for internal use. As the Company already has a  policy
of  capitalizing  internal use software, the Company  does  not
believe  that  the adoption of this SOP will  have  a  material
effect  on the Company's consolidated results of operations  or
financial position.

LITIGATION

The  Company is from time to time involved in legal proceedings
of  a  character  normally incident to its business,  including
various threatened and pending claims seeking damages from  the
Company. Such incidental litigation includes claims related  to
employment,  environmental, personal injury, contract,  product
liability, and intellectual property matters. The Company  does
not  believe that an adverse decision in any presently  pending
or threatened claim, or any amounts it would be required to pay
by  reason thereof, would have a material adverse effect on its
financial condition or results of operations.

BUSINESS OUTLOOK

In order to provide our shareholders with better insight to our
future plans, directions, and objectives, the following
forward looking statements are provided.

<PAGE> 32

MARKETS:  The  Company  intends to continue  to  emphasize  the
industrial  and  process control and test  and  instrumentation
markets  in  which it holds a leadership position in  order  to
protect and enhance market penetration. The Company expects
to  hold  a steady market position in the digital audio market.
In addition, it will endeavor to improve its market position in
the  relatively  larger  and faster growth  communications  and
computing markets.

PRODUCTS:  The Company possesses very strong core  competencies
in   the  development,  manufacture,  and  marketing  of   high
performance  analog  and mixed signal integrated  circuits.  It
also maintains a strong presence in digital audio applications.
Increasingly,  it has been expanding its product  offerings  to
selected   aspects  of  the  communications  market,  including
wireless and broadband applications. The Company believes that,
by  using these capabilities to address the requirements of its
target markets, it can sustain substantial growth over the next
five  years.  To capitalize on rapid growth opportunities,  the
Company  is seeking to increase its number of product offerings
and  reduce the time required to bring new products to  market.
The  Company  is  also seeking to design products  for  a  wide
customer  base.  Product offerings will include  both  standard
linear  products  which  will serve  a  wide  range  of  market
applications  and, on a selective basis, products which  target
specific needs of very high growth market segments.

GROSS  MARGIN:  The  Company's plans  call  for  a  continually
expanding  gross  margin  over the  next  five  years.  Product
pricing  is  expected to remain stable and continue to  reflect
the  high  value-added content of these products.  Accordingly,
the  Company's ability to increase revenues will depend in part
upon  its  ability to increase unit sales volumes  of  existing
products  and  to  introduce and sell new  products.  Increased
volume  and  improved manufacturing efficiency are expected  to
continue to reduce product costs. Some products targeting  very
high volume, rapid growth applications will be characterized by
relatively lower gross margins but should require lower  levels
of   operating   costs  compared  to  products   serving   more
traditional markets.

OPERATING  EXPENSES:  In order to support acceleration  of  new
product development, the Company will continue to increase
its  R&D  expenditures. The Company intends to constrain  SMG&A
expenses  to  a rate substantially lower than that  of  revenue
growth.  The  goal is continual expansion of operating  margins
with  sales  growth while allowing for increased  research  and
development investment as the primary engine of that growth.

INVESTMENTS:  The  Company  believes the  growth  opportunities
inherent in this strategy will require significant additions to
manufacturing capacity and technological capabilities over  the
next five years. This will be met in the form of internal
capital  investments  and  development  of  source  of   supply
arrangements  with  third party vendors as  well  as  potential
timely and synergistic business acquisitions.

MARKET  RISKS:  The  Company is exposed  to  certain  financial
market risks, principally changes in interest rates and foreign
currency exchange rates.

INTEREST RATE RISKS: As the Company is virtually debt-free, the
Company's interest rate risk at December 31, 1998 relates
primarily  to  its cash equivalents, short-term  and  long-term
investments.

The following summarizes the future maturities of the Company's
cash equivalents, short-term and long-term investments
at December 31, 1998:

FOREIGN  CURRENCY RISKS: International markets  account  for  a
majority of the Company's revenue. The resulting transactions
have  exchange rate fluctuation risk associated with them.  The
company  acts  to  minimize  the  impact  of  foreign  currency
exchange  rate transactions through natural hedges afforded  by
its  significant  foreign operations and  through  the  use  of
financial  hedges in the form of forward contracts  and  option
contracts.  These  contracts have historically  been  in  three
currencies,  Japanese  Yen, British Pounds  and  German  Marks,
although  such contracts have been exclusively in Japanese  Yen
in 1997 and 1998. The following summarizes the foreign currency
forward  contracts, which settle in 1999, in effect at December
31, 1998:

</TABLE>

FACTORS  AFFECTING FUTURE RESULTS: The Company's quarterly  and
annual  operating results are affected by a variety of  factors
that could materially and adversely affect revenue, net income,
gross profit and profitability, including the volume and timing
of  orders,  changes in product mix, market acceptance  of  the
Company's  and  its  customers' products,  competitive  pricing
pressures,  fluctuations  in foreign currency  exchange  rates,
economic  conditions  in  the United States  and  international
markets,  the timing of new product introductions, availability
of  wafers  and  other materials and services, fluctuations  in
manufacturing   yields  and  the  continued  service   of   key
management,   employees   and  providers.   The   Company   has
experienced  significant fluctuations in operating  results  in
the  past  and may likely experience such fluctuations  in  the
future. The semiconductor market has historically been cyclical
and subject to significant economic downturns at various times.
As  noted  above,  the  industry is  currently  experiencing  a
downturn and the Company is unable to predict the likely extent
or  duration  of  this downturn. Historically, average  selling
prices  in the semiconductor industry have decreased  over  the
life  of  particular  products. If the  Company  is  unable  to
introduce new products with higher average selling prices or is
unable to reduce manufacturing costs to offset decreases in the
prices  of  its  existing  products,  the  Company's  operating
results will be adversely affected. In addition, the Company is
limited  in its ability to reduce costs quickly in response  to
any revenue shortfalls.

The  fabrication of integrated circuits is a highly complex and
precise  process.  Manufacturing yields can be  impacted  by  a
variety  of  factors, many of which are outside  the  Company's
control. A large portion of the Company's manufacturing costs
are  relatively fixed and consequently the number of  shippable
die  per wafer for a given product is critical to the Company's
results  of  operations. To the extent  the  Company  does  not
achieve  acceptable manufacturing yields or experiences product
shipment  delays,  its  financial condition,  cash  flows,  and
results   of  operations  would  be  materially  and  adversely
affected.  To meet anticipated future demand and to  utilize  a
broader range of fabrication processes, the Company intends  to
increase  its  manufacturing capacity  at  some  future  point.
Although the Company has internal capability to produce  wafers
for many of its products, it is dependent on outside wafer fabs
for a significant portion of its wafer supply. As is typical in
the  semiconductor industry, from time to time the Company  has
experienced disruptions in the supply of processed wafers  from
external  fabs due to quality and yield problems  and  capacity
constraints. If these outside wafer foundries are not able  to
produce required supplies of processed wafers conforming to the
Company's   quality  standards,  the  Company's  business   and
relationships with its customers for the quantities of products
produced  by  these foundries could be adversely  affected.  In
addition,  the  Company  relies on domestic  and  international
subcontractors  to  perform  assembly,  packaging  and  testing
services.  Disruption of these services could adversely  affect
the Company's operations.

The  Company  desires  to  continue to  expand  its  operations
outside   of   the  United  States  and  to  enter   additional
international   markets,   which   will   require   significant
management  attention and financial resources and  subject  the
Company  further  to  the  risks of operating  internationally.
These   risks   include   unexpected  changes   in   regulatory
requirements,  delays  resulting from difficulty  in  obtaining
export licenses for certain technology, tariffs, and other

<PAGE> 34

barriers and restrictions and the burdens of complying  with  a
variety  of  foreign  laws. In addition, because  most  of  the
Company's  international  sales  are  denominated  in   foreign
currencies, gains and losses on the conversion to U.S.  dollars
of  accounts  receivable  and  accounts  payable  arising  from
international operations may contribute to fluctuations in  the
Company's  operating  results. A  substantial  portion  of  the
Company's  revenue  is  attributable  to  sales  in  Japan  and
Southeast  Asia. The recent economic instability in  Japan  and
Southeast Asia has had a negative impact on the Company's sales
during  1998 and there can be no assurance that this  condition
will not continue. This situation could have a material adverse
effect  on  the  Company's business, financial condition,  cash
flows  or  operating results, particularly to the  extent  that
this  instability  materially impacts  the  sales  of  products
manufactured by the Company's customers.

The  Company  has in the past been, and may in the  future  be,
subject to or initiate intellectual property litigation in the
United  States  or  elsewhere,  which  can  demand  significant
financial and management resources. From time to time, third
parties  assert  that  the  Company is infringing  intellectual
property rights of such parties. There can be no assurance that
infringement  claims  by third parties  will  not  be  asserted
against  the Company in the future or that such assertions,  if
proven  to  be true, will not materially adversely  effect  the
Company's   business,  financial  condition,  cash   flows   or
operating  results. Any litigation relating to the intellectual
property  rights,  whether or not determined in  the  Company's
favor  or settled by the Company, would at a minimum be  costly
and  could  divert the efforts and attention of  the  Company's
management and technical personnel, which could have a material
adverse  effect on the Company's business, financial condition,
cash flows or operating results.

The  Company's success depends upon its ability to develop  new
products  for  existing  and  new markets,  to  introduce  such
products  in  a  timely manner and to have such  products  gain
market  acceptance. The development of new products  is  highly
complex,  and  from  time to time the Company  has  experienced
delays  in developing and introducing new products.  Successful
product  development and introduction depends on  a  number  of
factors,  including  proper  new  product  definition,   timely
completion  of design and testing of new products,  achievement
of acceptable manufacturing yields and market acceptance of the
Company's  and  its  customers' products. Moreover,  successful
product  design and development is dependent on  the  Company's
ability to attract, retain and motivate qualified analog design
engineers, of which there is a limited number. There can be  no
assurance  that  the  Company  will  be  able  to  meet   these
challenges  or adjust to changing market conditions as  quickly
and  cost-effectively as necessary to compete successfully. The
semiconductor   industry  is  intensely  competitive   and   is
characterized  by  price erosion, rapid  technological  change,
product  obsolescence and heightened international  competition
in  many  markets.  Many  of  the  Company's  competitors  have
substantially   greater   financial,   technical,    marketing,
distribution,  and other resources, broader product  lines  and
longer  standing relationships with customers than the Company.
In  the  event of a downturn in the market for analog circuits,
companies  that have broader product lines and longer  standing
customer   relationships  may  be  in  a  stronger  competitive
position  than the Company. Competitors with greater  financial
resources or broader product lines also may have more resources
than the Company to engage in sustained price reductions in the
Company's primary markets to gain market share.

Exhibit 10.3 - Burr-Brown Corporation Employee Retirement Plan

                    Second Amendment to the
        Burr-Brown Corporation Employee Retirement Plan
                               
     THIS AMENDMENT is made and entered into by BURR-BROWN
CORPORATION, a Delaware Corporation ("Burr-Brown").

                           RECITALS:

     WHEREAS, Burr-Brown desires to amend the Burr-Brown
Corporation Employee Retirement Plan (the "Plan"), to make

          (1)  The monthly benefit payable in the basic form provided in
            Section 6.2 commencing on a Participant's Normal Retirement
            Date that the Participant has earned as of any given date,
            determined in accordance with Section 5.8.  In no event shall
            the monthly Accrued Benefit of any Participant with at least
            twenty (20) years of Credited Service as of December 31, 1988
            (the last day of the 1988 Plan Year) be less than the amount of

(2)  For purposes of determining benefits payable on or after
January 1, 1998, - the monthly benefit payable in the basic
form provided in Section 6.2 commencing on a Participant's

II.  Section 2.1(c), Definition of Actuarially Equivalent, Page
2, is replaced in its entirety with the following new Section
2.1(c) to read as follows:

     (c)   "Actuarially Equivalent" - Of equal current value
when computed on the basis of actuarial procedures,
assumptions, factors and tables. Actuarially Equivalent factors
are the appropriate numerical ratios (determined on the basis
of actuarial assumptions which may differ from those used in
establishing Plan costs and liabilities) which enable a benefit
that is Actuarially Equivalent to another benefit to be
calculated. Except to the extent otherwise required for lump
sum distributions under Sections 5.4, 5.5, 5.10, 5.11, in
computing Actuarially Equivalent benefits, the Actuary shall
use the following assumptions:

    (1)  Pre-retirement interest assumption-six percent (6%);

    (2)  Post-retirement interest assumption-six percent (6%);

    (3)  Mortality table-UP-1984, a unisex mortality table

or 6.4(c) and in calculating Minimum Benefits under Sections
5.2(b) and 5.8(b), the Actuary shall use the following
assumptions:
          
    (1)  Interest Rate: the annual yield for Thirty (30)-Year
         Treasury Constant Maturities, as reported in Federal Reserve
         Statistical Release G.13 and H.15, for the calendar month
         preceding the first day of the Plan Year in which the Present
         Value is to be determined or in which the lump sum distribution
         is to be made.
         
    (2)  Mortality Table: the table prescribed by the Secretary of
         the Treasury that is based on the prevailing commissioner's
         standard table used to determine reserves for group annuity
         contracts issued on the date as of which the Present Value is
         being determined.

III. Section 2.1(s), Definition of Earnings, Page 6, is
replaced in its entirety with the following new Section 2.1(s)
to read as follows:

     (s)  "Earnings" -The total amount received by the
Participant from the Employer as regular salary or wages which
is subject to tax under Code Section 3402(a) during the Plan
Year, including Employer-paid short term disability pay, plus
any elective contributions made on the Employee's behalf
pursuant to salary deferral or reduction arrangements in effect
under Code Section 125, 401(k), 408(k) and 403(b) with the
Employer or any Affiliate.  However, the following items shall
be excluded from Earnings: overtime pay; discretionary or
formula bonuses; contributions to or benefits from any employee
welfare or pension benefit plan (as those terms are defined in
the Act) except for the elective contributions specified above;
workman's compensation benefits; imputed compensation such as
PS58 or Table I costs of life insurance; any deferred
compensation payments; and any other form of irregular
payments.  Notwithstanding the foregoing, the "Earnings" of a
Participant receiving commission income from the Employer shall
not exceed the maximum base salary payable to such Participant
for the applicable Plan Year.  Notwithstanding the foregoing,
the "overtime pay" of a Participant whose regularly scheduled
work week alternates between 48 hours one week and 36 hours the
next week, shall be all Compensation received for hours worked
in excess of the regularly scheduled 48 hours, plus
Compensation received in excess of the base rate of pay for
hours worked in excess of 40 hours but not more than 48 hours
for the week where 48 hours is the regularly scheduled hours,
and all Compensation received for hours worked in excess of the
regularly scheduled 36 hours for the week where 36 hours is the
regularly scheduled hours.  Notwithstanding the foregoing, in
the event that the Plan is a Top Heavy Plan during a Plan Year,
"Earnings" in excess of Two Hundred Thousand Dollars
($200,000.00) during such Plan year shall be disregarded for
all relevant purposes.  Such Two Hundred Thousand Dollar
($200,000.00) limitation shall be adjusted for each Plan Year
commencing on or after January 1, 1988 to take into account any
cost-of-living increase adjustment for that Plan Year allowable
pursuant to the applicable Treasury regulations or rulings
under Code Section 416(d)(2) and Code Section 415(d).
Notwithstanding the foregoing, the Accrued Benefit earned by
any Employee (including the family unit of a Highly Compensated
Employee, as described below) for any Plan Year within the
period commencing January 1, 1989 and ending December 31, 1993
shall not be based on Earnings in excess of Two Hundred
Thousand Dollars ($200,000.00).  This latter Two Hundred
Thousand Dollar ($200,000.00) limitation shall be adjusted for
each Plan Year commencing after December 31, 1988 to take into
account any cost-of-living increase adjustment for that Plan
Year allowable pursuant to the applicable Treasury regulations
or rulings under Code Section 401(a)(17)(B).

     Notwithstanding the foregoing, the Accrued Benefit earned
by any Employee (including the family unit of a Highly
Compensated employee, as described below) for each Plan Year
commencing on or after January 1, 1994 shall not be based on
Earnings in excess of One Hundred Fifty Thousand Dollars
($150,000.00).  If, for any calendar year after 1994,  the
excess (if any) of:

     (i)  the One Hundred Fifty Thousand Dollars ($150,000.00)
limitation increased by the cost-of-living adjustment for that
calendar year, over

     (ii) the dollar limitation in effect for the Plan Year
beginning in the calendar year is equal to or greater than
$10,000,

     then the One Hundred Fifty Thousand Dollar ($150,000.00)
limit (as previously adjusted under this sentence) for any Plan
Year beginning in any subsequent calendar year shall be
increased by the amount of such excess, rounded to the next
lowest multiple of $10,000.  The One Hundred Fifty Thousand
Dollar ($150,000.00) limitation shall be adjusted for increases
in the cost-of-living in accordance with Code Section
401(a)(17)(B) and the Treasury regulations thereunder;
provided, however, the base period for purposes of Code Section
401(a)(17)(B) shall be the calendar quarter beginning October
1, 1993.

     For purposes of applying the $200,000 or the $150,000
limit to Earnings of the family unit of each Highly Compensated
Employee, the family unit will be treated as a single employee
with one Earnings and the $200,000 limit or the $150,000 limit,
as applicable, will be allocated among the members of the
family unit in proportion to each member's Earnings (except for
the purposes of determining Earnings below the Plan's
integration level).  For this purpose, a family unit is the
Highly Compensated Employee such employee's spouse, and such
employee's lineal descendants who have not attained age 19
before the close of the Plan Year.

IV.  Section 4.3, Disability, Page 21, is replaced in its
entirety with the following new Section 4.3 to read as follows:

     4.3   DISABILITY.  Should a Participant become Disabled
prior to retirement or any other separation from employment
with the Employer (prior to January 1, 1998, Participants were
required to have at least five (5) years of Continuous Service
as of the last day of his period of active employment with the
Employer), then that Participant shall be entitled to a
Disability benefit as provided in Section 5.3 of the Plan. A
Participant's Disability retirement benefit payments shall
commence as of the first day of the calendar month following
the Participant's separation from employment due to Disability.
Disability retirement benefit payments shall not be payable for
any earlier month. In no event shall a Participant be entitled
to receive simultaneously both a Disability retirement benefit
and a normal, early or termination retirement benefit.

V.   Section 4.4, Death Benefits, Page 21-22, is replaced in
its entirety with the following new Section 4.4 to read as
follows:

     4.4   DEATH.  Should a Participant die prior to
retirement, Disability or any other separation from employment
(prior to January 1, 1998, benefits under this Section 4.4
required at least five (5) years of Continuous Service), then
the beneficiary of that Participant shall be entitled to the
benefits (if any) provided under Section 5.4 and Section 5.5 of
the Plan. Any death benefits payable to an unmarried
Participant in accordance with Section 5.4 shall commence as
soon as possible following that Participant's death and shall
be paid in the form set forth in Section 5.4 of the Plan. Death
benefits payable with respect to a married Participant shall be
payable in accordance with the surviving spouse annuity
provisions set forth in Section 5.5 of the Plan.  A special
death benefit shall be payable in accordance with Section 5.6
upon the death of a retired participant.

     Each Participant shall have the right to designate, on a
form supplied by and delivered to the Plan Administrator, a
beneficiary or beneficiaries to receive benefits pursuant to
this Section 4.4 in the event of his death. Each Participant
may change his beneficiary designation from time to time.  Upon
receipt of such designation by the Plan Administrator, such
designation or change of designation shall become effective as
of the date of the designation. However, a beneficiary
designation filed by a married Participant designating a
beneficiary other than his Spouse shall not be effective,
unless the Spouse consents to such designation in accordance
with the spousal consent requirements of Section 6.6. There
shall be no liability on the part of the Employer, the Plan
Administrator or the Trustee with respect to any payment
authorized by the Plan Administrator in accordance with the
most recent valid beneficiary designation of the Participant in
its possession before receipt of a more recent valid
beneficiary designation.  If no designated beneficiary is
living when benefits become payable, or if there is no validly
designated beneficiary, then the beneficiary shall be the
Participant's Spouse.  If there is no such validly designated
beneficiary or surviving Spouse, then the beneficiary shall be
the estate of the Participant.

             of which is the actual completed full years and
             months (expressed as fractions of a year) of the
             Participant's Credited Service as of the
             determination date and the denominator of which is

             months (expressed as fractions of a year) of
             Credited Service that would have been credited to
             such Participant had he separated from employment
             on his Normal Retirement Date.
         (2) ESTIMATING NORMAL RETIREMENT BENEFITS. The
             Plan Administrator will estimate the normal
             retirement benefits (determined in accordance with
             Section 5.1(a) to which each Participant will be
             entitled on his Normal Retirement Date. In making
             its estimate, the Plan Administrator shall assume
             that the Participant will continue his service
             with Employer to his Normal Retirement Date and
             that his Average Monthly Earnings on his Normal

Age).

Top Heavy Plan, a Participant's Accrued Benefit shall be the
greater of the amount determined pursuant to the foregoing
provisions of this Section 5.8 or the amount determined

     (d)  RECALCULATION OF ACCRUED BENEFIT OF PARTICIPANTS IN
PAY STATUS. The Accrued Benefit of a Participant who earns
additional years of Credited Service after receiving any
distribution from the Plan shall be equal to the excess of (1)
over (2):
         (1) The Participant's Accrued Benefit determined
             under the applicable section of ARTICLE V on his
             Calculation Date (as defined herein) based on all
             years of Credited Service earned during the period
             of the Participant's employment; and
         (2) The monthly amount which is Actuarially
             Equivalent to the aggregate benefits distributed
             to the Participants from the Plan prior to the
             Calculation Date which were paid as monthly
             amounts (a) for any month prior to the
             Participant's Normal Retirement Date and (b) for
             any month in which the Participant was an active
             Employee after his Normal Retirement Date.
 
     Notwithstanding the foregoing, such recomputed monthly
benefit shall not be less than the monthly benefit received by
the Participant prior to his Calculation Date converted to a
monthly annuity for the life of the Participant payable as of
the Calculation Date. The first recomputed payment shall
include any retroactive payments due for any month within the
suspension period under Section 6.8 in which the Participant
was not an active Employee. Also the first recomputed payment
shall be reduced to the extent permitted under Department of
Labor Regulations Section 2530.203 by any payment made to the
Participant under which he was not entitled to receive pursuant
to the suspension of provisions in effect under Section 6.8.
The recomputation under this Section 5.8 shall be made as of
each Calculation Date, and such purpose the "Calculation Date"
for a Participant who earns Credited Service after receiving
one or more benefit payments under ARTICLE V of the Plan will
be each January 1 and the date he subsequently terminates
employment with the Employer.

     (e)  "Account Balance" - single lump sum dollar amount
determined and predetermined for each Employee (without regard
to any actual contributions to the Trust Fund or the income,

under the Plan) from time to time as follows:

        (1) "Initial Account Balance" - As of January 1, 1998, the
            initial Account Balance for each Employee equals zero.
        (2) "Additional Accruals" - Quarterly, at the end of each

            as designated by the Employer, beginning March 31, 1998, there
            shall be credited to each Employee's Account Balance an amount
            equal to two percent (2%) multiplied by such Employee's actual
            Earnings for such calendar quarter.  If an Employee shall have
            a Termination Date prior to the end of such calendar quarter,
            then such Employee shall not receive an Additional Accrual for
            the calendar quarter in which his or her Termination occurs.
        (3) "Interest Credit" -- Quarterly, at the end of each
            calendar quarter, that is on March 31, June 30, September 30,

            Employee an amount equal to one-fourth (1/4) of the Investment
            Percentage Rate appropriate for the Plan Year multiplied by the
            Account Balance determined as of the first day of such calendar
            quarter.
 
            Interest credits will continue to be credited for
            each calendar quarter up until the first day of
            the quarter in which payments are first made to
            the Employee or forfeitures are taken under the
            Plan.
 
            In addition, a final "Interest Credit" will be
            determined for the calendar quarter in which

            Credit shall be an amount equal to one-twelfth
            (1/12) of the Investment Percentage Rate
            appropriate for the Plan Year multiplied by the
            number of completed months (if any) from the first
            day of such calendar quarter to the date payments
            are first made to the Employee, multiplied by the
            Account Balance determined as of the first day of
            such calendar quarter.

            Treasury constant Maturities, as reported in
            Federal Reserve Statistical Release G.13 and H.15,
            for the calendar month preceding the first day of
            the Plan Year.
            
            (ii) for Plan Years beginning on or after January
            1, 1999, the annual yield for Thirty (30)-Year
            Treasury constant Maturities, as reported in

            the Plan Year.
            
    XI.  Section 5.10, Cash Outs and Repayment of Distributions,
Page 27, is replaced in its entirety with the following new
Section 5.10 to read as follows:

    5.10 CASH OUTS AND REPAYMENT OF DISTRIBUTIONS.  If the
termination benefit payable to a Participant pursuant to
Section 5.7 is Actuarially Equivalent to a lump sum
distribution of Five Thousand Dollars ($5,000) or less, the
Plan Administrator shall direct the Trustee to pay the
termination benefit in the form of a lump sum distribution not
later than sixty (60) days after the close of the Plan Year
following the Plan Year in which the Participant's employment
terminates, subject, however, to any earlier payment date
required pursuant to the provisions of Section 6.1. No
distribution may be made pursuant to the preceding sentence
after the Annuity Starting Date unless the Participant and the
Participant's spouse, if any, (or where the Participant has
died, his spouse alone) consent in writing to such
distribution. A Participant who receives a lump sum
distribution of his Accrued Benefit shall be given the
opportunity to repay the full amount of that distribution, plus
interest at a rate determined  under Code Section 411(c)(2)(C),
should he return to employment with the Employer or any
Affiliate. The repayment may be made at any time prior to the
earlier of (a) the end of the five (5)-year period measured
from the first date on which the Participant is subsequently
reemployed by Employer or (b) the incurrence of a Break in
Continuous Service of sixty (60) months measured from the date
of the prior distribution. If a Participant does not exercise
his right to repay the prior distribution (with interest as
provided above) in such a timely manner, the years and months
of Credited Service performed by the Participant prior to the
distribution shall be disregarded in calculating his normal
retirement benefit and his Accrued Benefit.

    XII. Section 5.11, Other Small Benefits, Page 28, is replaced
in its entirety with the following new Section 5.11 to read as
follows:

    5.11 OTHER SMALL BENEFITS.  In the event that the
Actuarially Equivalent present value of the Qualified Joint and
50% Survivor Annuity, Life Only Annuity, or Qualified Pre-
retirement Survivor Annuity payable with respect to a
Participant is less than Five Thousand Dollars ($5,000), the
Plan Administrator shall direct that such Actuarially
Equivalent present value be distributed to the Participant (or
to the Participant's Beneficiary if the Participant has died)
in a lump sum as soon as administratively feasible following
the Participant's retirement, death, Disability, or Termination
Date.  Notwithstanding the preceding, a lump sum payment shall
not be made under this Section 5.11 after the Annuity Starting
Date without the written consent of the Participant and his or
her Spouse (or, if the Participant has died, his or her
Surviving Spouse's written consent) to such distribution.

    XIII.  Section 6.4, Optional Methods of Distribution, Pages 36-
37, the following new paragraph (c) is added to the end of
Section 6.4 to read as follows:

    (c)  A Participant may elect to receive a lump sum distribution
(payable as soon as administratively feasible) following the
Participant's retirement, Disability, or Termination Date of
the portion of the Actuarially Equivalent present value of the
Participant's Normal Retirement Benefit, Early Retirement
Benefit, Disability Benefit, or Accrued Benefit that equals his
or her Account Balance.

     If a Participant elects to receive a lump sum distribution
under this Section 6.4(c), and the excess of the Actuarially
Equivalent present value of the Participant's Normal Retirement
Benefit, Early Retirement Benefit, Disability Benefit, or
Accrued Benefit over his or her Account Balance does not exceed
Five Thousand Dollars ($5,000), such excess shall, at the
election of the Participant, be distributed to the Participant
at the same time as his or her Account Balance is distributed
pursuant to this Section 6.4(c).

     If a Participant elects to receive a lump sum distribution
and the excess of the Actuarially Equivalent present value of
the Participant's Normal Retirement Benefit, Early Retirement
Benefit, Disability Benefit, or Accrued Benefit over his or her
Account Balance equals or exceeds Five Thousand Dollars
($5,000), such excess shall be distributed (at the time allowed
by Section 6.1 in the form of a Qualified Joint and 50%
Survivor Annuity or Life Only Annuity whichever is applicable
pursuant to ARTICLE VI.

     IN WITNESS WHEREOF, Burr-Brown has executed this Amendment

Section 4.  INVESTMENT OF TRUST.

     (a)  SELECTION OF INVESTMENT OPTIONS.  The Trustee shall

vote the shares credited to the participant's accounts (both
vested and unvested).  The Trustee shall vote the shares as
directed by the participant.  The Trustee shall not vote shares
for which it has received no directions from the participant.

     During the Recordkeeping Reconciliation Period, the Named
Fiduciary shall have the right to direct the Trustee as to the
manner in which the Trustee is to vote the shares of the Mutual
Funds in the Trust.   Following the Recordkeeping
Reconciliation Period the Named Fiduciary shall continue to
have the right to direct the Trustee as to the manner in which
the Trustee is to vote the Mutual Fund shares held in a short-
term liquidity reserve for a unitized investment option.

     With respect to all rights other than the right to vote,
the Trustee shall follow the directions of the participant and
if no such directions are received, the directions of the Named
Fiduciary.  The Trustee shall have no further duty to solicit

Stock.  The Trustee shall not be liable for any loss, or by
reason of any breach, which arises from the directions of the
Named Fiduciary with respect to the acquisition and holding of
Sponsor Stock, unless it is clear on their face that the
actions to be taken under those directions would be prohibited
by the foregoing fiduciary duty rules or would be contrary to
the terms of this Agreement.

          (iii)  EXECUTION OF PURCHASES AND SALES.

               (A)  Purchases and sales of Sponsor Stock (other
than for exchanges) shall be made on the open market on the
date on which the Trustee receives from the Administrator in
good order all information,  documentation, and wire transfer
of funds (if applicable), necessary to accurately effect such
transactions.   Exchanges of Sponsor Stock shall be made in
accordance with the Exchange Guidelines attached hereto as
Schedule "G".  Such general rules shall not apply in the
following circumstances:

                    (1)  If the Trustee is unable to purchase
or sell the total number of shares required to be purchased or
sold on such day as a result of market conditions; or

                    (2)  If the Trustee is prohibited by the
Securities and Exchange Commission, the New York Stock
Exchange, or any other regulatory body from purchasing or
selling any or all of the shares required to be purchased or
sold on such day.

In the event of the occurrence of the circumstances described
in (1) or (2) above, the Trustee shall purchase or sell such
shares as soon as possible thereafter and shall determine the
price of such purchases or sales to be the average purchase or
sales price of all such shares purchased or sold, respectively.
The Trustee may follow directions from the Named Fiduciary to
deviate from the above purchase and sale procedures provided
that such direction is made in writing by the Named Fiduciary.

             (B)  PURCHASES AND SALES FROM OR TO SPONSOR.  If
directed by the Sponsor in writing prior to the trading date,
the Trustee may purchase or sell Sponsor Stock from or to the
Sponsor if the purchase or sale is for adequate consideration
(within the meaning of section 3(18) of ERISA) and no
commission is charged.  If Sponsor contributions (employer) or
contributions made by the Sponsor on behalf of the participants
(employee) under the Plan are to be invested in Sponsor Stock,
the Sponsor may transfer Sponsor Stock in lieu of cash to the
Trust.  In either case, the number of shares to be transferred
will be determined by dividing the total amount of Sponsor
Stock to be purchased or sold by dividing the total amount of
Sponsor Stock to be purchased or sold by the 4:00 p.m. NYSE
closing price of the Sponsor Stock on the trading date.

            (C)  USE OF AN AFFILIATED BROKER.  The Named
Fiduciary hereby directs the Trustee to use Fidelity Capital
Markets and its affiliates ("Capital Markets") to provide
brokerage services in connection with any purchase or sale of
Sponsor Stock in accordance with directions from Plan
participants.  Capital Markets shall execute such directions
directly or through its affiliate, National Financial Services
Company ("NFSC").  The provision of brokerage services shall be
subject to the following:

Sponsor Stock up to 10,000 shares in a singular transaction,
four cents ($.04) commission on each share of Sponsor Stock
from 10,001 to 20,000 shares in a singular transaction, and
three and one-half cents ($.035) commission on each share of
Sponsor Stock in excess of 20,000 shares in a singular
transaction.  Any change in such remuneration may be made only
by a signed agreement between Sponsor and Trustee.

                 (2)  The Trustee will provide the Sponsor
with a description of Capital Markets' brokerage placement
practices and a form by which the Sponsor may terminate this
direction to use a broker affiliated with the Trustee.  The
Trustee will provide the Sponsor with this termination form
annually, as well as quarterly and annual reports which
summarize all securities transaction-related charges incurred
by the Plan.

                 (3)  Any successor organization of Capital
Markets, through reorganization, consolidation, merger or
similar transactions, shall, upon consummation of such
transaction, become the successor broker in accordance with the
terms of this direction provision.

                 (4)  The Trustee and Capital Markets shall
continue to rely on this direction provision until notified to
the contrary.  The Sponsor reserves the right to terminate this
direction upon written notice to Capital Markets (or its
successor) and the Trustee, in accordance with Section 11 of
this Agreement.

          (iv)  SECURITIES LAW REPORTS.  The Administrator

                   (4)  A participant who has directed the
Trustee to tender some or all of the shares of Sponsor Stock
credited to the participant's accounts may, at any time prior
to the tender offer withdrawal date, direct the Trustee to
withdraw some or all of the tendered shares, and the Trustee
shall withdraw the directed number of shares from the tender
offer prior to the tender offer withdrawal deadline.  Prior to
the withdrawal deadline, if any shares of Sponsor Stock not
credited to participants' accounts have been tendered, the
Trustee shall redetermine the number of shares of Sponsor Stock
that would be tendered under Section 4(e)(v)(B)(3) if the date
of the foregoing withdrawal were the date of determination, and
withdraw from the tender offer the number of shares of Sponsor
Stock not credited to participants' accounts necessary to
reduce the amount of tendered Sponsor Stock not credited to
participants' accounts to the amount so redetermined.  A
participant shall not be limited as to the number of directions
to tender or withdraw that the participant may give to the
Trustee.

                   (5)  A direction by a participant to the
Trustee to tender shares of Sponsor Stock credited to the
participant's accounts shall not be considered a written
election under the Plan by the participant to withdraw, or have
distributed, any or all of his withdrawable shares.  The
Trustee shall credit to each account of the participant from
which the tendered shares were taken the proceeds received by
the Trustee in exchange for the shares of Sponsor Stock
tendered from that account.  Pending receipt of directions
(through the Administrator) from the participant or the Named
Fiduciary, as provided in the Plan, as to which of the
remaining investment options the proceeds should be invested
in, the Trustee shall invest the proceeds in the investment
option described in Schedule "C".

              (vi) GENERAL.  With respect to all rights other
than the right to vote, the right to tender, and the right to
withdraw shares previously tendered, in the case of Sponsor
Stock credited to a participant's accounts, the Trustee shall
follow the directions of the participant and if no such
directions are received, the directions of the Named Fiduciary.
The Trustee shall have no duty to solicit directions from
participants.  With respect to all rights other than the right
to vote and the right to tender, in the case of  Sponsor Stock
not credited to participants' accounts, the Trustee shall
follow the directions of the Named Fiduciary.

              (vii) CONVERSION.  All provisions in this
Section 4(e) shall also apply to any securities received as a
result of a conversion of Sponsor Stock.


     (f)  PARTICIPANT LOANS. (i) GENERAL PURPOSE LOANS  The
Administrator shall act as the Trustee's agent for participant
general purpose loan notes and as such shall (i) separately
account for repayments of such general purpose loans and
clearly identify such assets as Plan assets and (ii) collect
and remit all principal and interest payments to the Trustee.
To originate a participant general purpose loan, the Plan
participant shall direct the Trustee as to the term and amount
of the loan to be made from the participant's individual
account.  Such directions shall be made by Plan participants by
use of the telephone exchange system maintained for such
purpose by the Trustee or its agent.  The Trustee shall
determine, based on the current value of the participant's
account on the date of the request and any guidelines provided
by the Sponsor, the amount available for the loan.  Based on
the interest rate supplied by the Sponsor in accordance with
the terms of the Plan, the Trustee shall advise the participant
of such interest rate, as well as the installment payment
amounts.  The Trustee shall distribute the Participant loan
agreement and truth-in-lending disclosure with the proceeds
check to the participant.  To facilitate recordkeeping, the
Trustee may destroy the original of any promissory note made in
connection with a loan to a participant under the Plan,
provided that the Trustee first creates a duplicate by a
photographic or optical scanning or other process yielding a
reasonable facsimile of the promissory note and the Plan
participant's signature thereon, which duplicate may be reduced
or enlarged in size from the actual size of the original
promissory note.
                               
          (ii)  LOANS FOR PURCHASE OF A PRIMARY RESIDENCE.  The
Administrator shall act as the Trustee's agent for the purpose
of holding all trust investments in participant loan notes for
the purchase of a primary residence and related documentation
and as such shall (i) hold physical custody of and keep safe
the notes and other loan documents, (ii) separately account for
repayments of such loans and clearly identify such assets as
Plan assets, (iii) collect and remit all principal and interest
payments to the Trustee, and (iv) cancel and surrender the
notes and other loan documentation when a loan has been paid in
full.  To originate a participant loan for the purchase of a
primary residence, the Plan participant shall direct the
Trustee as to the type of loan to be made from the
participant's individual account.  Such directions shall be
made by Plan participants by use of the telephone exchange
system maintained for such purpose by the Trustee or its agent.
The Trustee shall determine, based on the current value of the
participant's account, the amount available for the loan.
Based on the interest rate supplied by the Sponsor in
accordance with the terms of the Plan, the Trustee shall advise
the participant of such interest rate, as well as the
installment payment amounts.  The Trustee shall forward the
loan document to the participant for execution and submission
for approval to the Administrator.  The Administrator shall
have the responsibility for approving the loan and instructing
the Trustee to send the loan proceeds to the Administrator or
to the participant if so directed by the Administrator.  In all
cases, approval or disapproval by the Administrator shall be
made within thirty (30) days of the participant's initial
request (the origination date).
     
     (g)  INVESTMENT CONTRACTS.  Trust investments in
Investment Contracts shall be subject to the following
limitations:

          (i)  COLLECTIVE INVESTMENT FUNDS.  To the extent that
the Named Fiduciary selects as an investment option the Managed
Income Portfolio of the Fidelity Group Trust for Employee

agrees to the terms of the Group Trust and adopts said terms as
a part of this Agreement and (B) acknowledges that it has
received from the Trustee a copy of the Group Trust, the
Declaration of Separate Fund for the Managed Income Portfolio
of the Group Trust, and the Circular for the Managed Income
Portfolio.

          (ii)  PARTICIPATION IN COLLECTIVE INVESTMENT FUNDS.
The Named Fiduciary hereby (i) agrees to the Plan's
participation in the Fidelity Group Trust for Employee Benefit
Plans (the "Group Trust"), a group trust maintained by the
Trustee for qualified plans and adopts said terms as a part of
this Agreement and (ii) acknowledges that it has received from
the Trustee a copy of the terms of the Group Trust and the

     (h)  RELIANCE OF TRUSTEE ON DIRECTIONS.

          (i)  The Trustee shall not be liable for any loss, or

exercise or non-exercise of rights under this Section 4 over
the assets in the participant's accounts.

          (ii) The Trustee shall not be liable for any loss, or
by reason of any breach, which arises from the Named
Fiduciary's exercise or non-exercise of rights under this

to be taken under the Named Fiduciary's directions were
prohibited by the fiduciary duty rules of section 404(a) of
ERISA or were contrary to the terms of the Plan or this
Agreement.

     (i)  TRUSTEE POWERS.  The Trustee shall have the following
powers and authority:

          (i)  Subject to paragraphs (b) and  (c) of this
Section 4, to sell, exchange, convey, transfer, or otherwise

other property delivered to the Trustee or to inquire into the
validity, expediency, or propriety of any such sale or other
disposition.

          (ii) Subject to paragraphs (b) and (c) of this
Section 4, to invest in Investment Contracts and short term
investments (including interest bearing accounts with the
Trustee or money market mutual funds advised by affiliates of
the Trustee) and in collective investment funds maintained by
the Trustee for qualified plans, in which case the provisions
of each collective investment fund in which the Trust is
invested shall be deemed adopted by the Sponsor and the
provisions thereof incorporated as a part of this Trust as long
as the fund remains exempt from taxation under Sections 401(a)
and 501(a) of the Internal Revenue Code of 1986 (the "Code"),
as amended.

          (iii) To cause any securities or other property
held as part of the Trust to be registered in the Trustee's own
name, in the name of one or more of its nominees, or in the
Trustee's account with the Depository Trust Company of New York
and to hold any investments in bearer form, but the books and
records of the Trustee shall at all times show that all such
investments are part of the Trust.

          (iv) To keep that portion of the Trust in cash or
cash balances as the Named Fiduciary or Administrator may, from
time to time, deem to be in the best interest of the Trust.

          (v)  To make, execute, acknowledge, and deliver any
and all documents of transfer or conveyance and to carry out
the powers herein granted.

          (vi) To borrow funds from a bank not affiliated with

the investment fund(s) in need of liquidity.

          (vii) To settle, compromise, or submit to
arbitration any claims, debts, or damages due to or arising

reasonable expenses arising from any such action, from the
Trust if not paid by the Sponsor.

other assistance as may be required in carrying out the
provisions of this Agreement and to pay their reasonable
expenses and compensation from the Trust if not paid by the
Sponsor.

          (ix) To invest all of any part of the assets of the
Trust in any collective investment trust or group trust which
then provides for the pooling of the assets of plans described
in Section 401(a) and exempt from tax under Section 501(a) of
the Code, or any comparable provisions of any future
legislation that amends, supplements, or supersedes those
sections, provided that such collective investment trust or
group trust is exempt from tax under the Code or regulations or
rulings issued by the Internal Revenue Service; the provisions
of the document governing such collective investment trusts or
group trusts, as it may be amended from time to time, shall
govern any investment therein and are hereby made a part of
this Trust Agreement.

          (x)  To do all other acts although not specifically
mentioned herein, as the Trustee may deem necessary to carry
out any of the foregoing powers and the purposes of the Trust.

Section 5.  RECORDKEEPING AND ADMINISTRATIVE SERVICES TO BE
PERFORMED.

     (a)  GENERAL.  The Trustee shall perform those
recordkeeping and administrative functions described in
Schedule "A" attached hereto.  These recordkeeping and
administrative functions shall be performed within the
framework of the Administrator's written directions regarding
the Plan's provisions, guidelines and interpretations.

     (b)  ACCOUNTS.  The Trustee shall keep accurate accounts
of all investments, receipts, disbursements, and other
transactions hereunder, and shall report the value of the
assets held in the Trust as of the last day of each fiscal
quarter of the Plan and, if not on the last day of a fiscal
quarter, the date on which the Trustee resigns or is removed as
provided in Section 8 of this Agreement or is terminated as
provided in Section 10 (the "Reporting Date").  Within thirty
(30) days following each Reporting Date or within sixty (60)
days in the case of a Reporting Date caused by the resignation
or removal of the Trustee, or the termination of this
Agreement, the Trustee shall file with the Administrator a
written account setting forth all investments, receipts,
disbursements, and other transactions effected by the Trustee
between the Reporting Date and the prior Reporting Date, and
setting forth the value of the Trust as of the Reporting Date.
Except as otherwise required under ERISA, upon the expiration
of six (6) months from the date of filing such account with the
Administrator, the Trustee shall have no liability or further
accountability to anyone with respect to the propriety of its
acts or transactions shown in such account, except with respect
to such acts or transactions as to which the Sponsor shall
within such six (6) month period file with the Trustee written
objections.

     (c)  INSPECTION AND AUDIT.  All records generated by the
Trustee in accordance with paragraphs (a) and (b) shall be open
to inspection and audit, during the Trustee's regular business
hours prior to the termination of this Agreement, by the
Administrator or any person designated by the Administrator.
Upon the resignation or removal of the Trustee or the
termination of this Agreement, the Trustee shall provide to the
Administrator, at no expense to the Sponsor, in the format
regularly provided to the Administrator, a statement of each
participant's accounts as of the resignation, removal, or
termination, and the Trustee shall provide to the Administrator
or the Plan's new recordkeeper such further records as are
reasonable, at the Sponsor's expense.

     (d)  EFFECT OF PLAN AMENDMENT.  A confirmation of the
current qualified status of the Plan is attached hereto as
Schedule "F".  The Trustee's provision of the recordkeeping and
administrative services set forth in this Section 5 shall be
conditioned on the Sponsor delivering to the Trustee a copy of
any amendment to the Plan as soon as administratively feasible
following the amendment's adoption, with, if requested, an IRS
determination letter or an opinion of counsel substantially in
the form of Schedule "F" covering such amendment, and on the
Administrator providing the Trustee on a timely basis with all
the information the Administrator deems necessary for the
Trustee to perform the recordkeeping and administrative
services and such other information as the Trustee may
reasonably request.

     (e)  RETURNS, REPORTS AND INFORMATION.  The Administrator
shall be responsible for the preparation and filing of all
returns, reports, and information required of the Trust or Plan
by law.  The Trustee shall provide the Administrator with such
information as the Administrator may reasonably request to make
these filings.  The Administrator shall also be responsible for
making any disclosures to Participants required by law, except
such disclosure as may be required under federal or state truth-
in-lending laws with regard to Participant loans, which shall
be provided by the Trustee.

Section 6.  COMPENSATION AND EXPENSES.  Within thirty (30) days
of receipt of the Trustee's bill, which shall be computed and
billed in accordance with Schedule "B" attached hereto and made
a part hereof, as amended from time to time, the Sponsor shall
send to the Trustee a payment in such amount or the Sponsor may
direct the Trustee to deduct such amount from participants'
accounts.  All expenses of the Trustee relating directly to the
acquisition and disposition of investments constituting part of
the Trust, and all taxes of any kind whatsoever that may be
levied or assessed under existing or future laws upon or in
respect of the Trust or the income thereof, shall be a charge
against and paid from the appropriate Plan participants'
accounts.

Section 7.  DIRECTIONS AND INDEMNIFICATION.

     (a)  IDENTITY OF ADMINISTRATOR AND NAMED FIDUCIARY.  The
Trustee shall be fully protected in relying on the fact that
the Named Fiduciary and the Administrator under the Plan are
the individuals or persons named as such above or such other
individuals or persons as the Sponsor may notify the Trustee in
writing.

     (b)  DIRECTIONS FROM ADMINISTRATOR.  Whenever the
Administrator provides a direction to the Trustee, the Trustee
shall not be liable for any loss, or by reason of any breach,
arising from the direction (i) if the direction is contained in
a writing (or is oral and immediately confirmed in a writing)
signed by any individual whose name and signature have been
submitted (and not withdrawn) in writing to the Trustee by the
Administrator in the form attached hereto as Schedule "D", and
(ii) if the Trustee reasonably believes the signature of the
individual to be genuine, unless it is clear on the direction's
face that the actions to be taken under the direction would be
prohibited by the fiduciary duty rules of Section 404(a) of
ERISA or would be contrary to the terms of this Agreement.  For
purposes of this Section, such direction may also be made via
electronic data transfer ("EDT") in accordance with procedures
agreed to by the Administrator and the Trustee; provided,
however, that the Trustee shall be fully protected in relying
on such direction as if it were a direction made in writing by
the Administrator.

     (c)  DIRECTIONS FROM NAMED FIDUCIARY.  Whenever the Named
Fiduciary or Sponsor provides a direction to the Trustee, the
Trustee shall not be liable for any loss, or by reason of any
breach, arising from the direction (i) if the direction is
contained in a writing (or is oral and immediately confirmed in
a writing) signed by any individual whose name and signature
have been submitted (and not withdrawn) in writing to the
Trustee by the Named Fiduciary in the form attached hereto as
Schedule "E" and (ii) if the Trustee reasonably believes the
signature of the individual to be genuine, unless it is clear
on the direction's face that the actions to be taken under the
direction would be prohibited by the fiduciary duty rules of
Section 404(a) of ERISA or would be contrary to the terms of
this Agreement.  Such direction may also be made via EDT in
accordance with procedures agreed to by the Named Fiduciary and
the Trustee; provided, however, that the Trustee shall be fully
protected in relying on such direction as if it were a
direction made in writing by the Named Fiduciary.

     (d)  CO-FIDUCIARY LIABILITY.  In any other case, the
Trustee shall not be liable for any loss, or by reason of any
breach, arising from any act or omission of another fiduciary
under the Plan except as provided in section 405(a) of ERISA.

     (e)  INDEMNIFICATION.  The Sponsor shall indemnify the
Trustee against, and hold the Trustee harmless from, any and
all loss, damage, penalty, liability, cost, and expense,
including without limitation, reasonable attorneys' fees and
disbursements, that may be incurred by, imposed upon, or
asserted against the Trustee by reason of any claim, regulatory
proceeding, or litigation arising from any act done or omitted
to be done by any individual or person with respect to the Plan
or Trust, excepting only any and all loss, etc., arising solely
from the Trustee's negligence or bad faith.

     (f)  SURVIVAL.  The provisions of this Section 7 shall
survive the termination of this Agreement.

Section 8.  RESIGNATION OR REMOVAL OF TRUSTEE.

sixty (60) days' notice in writing to the Sponsor, unless a
shorter period of notice is agreed upon by the Sponsor.

     (b)  REMOVAL.  The Sponsor may remove the Trustee at any
time upon sixty (60) days' notice in writing to the Trustee,
unless a shorter period of notice is agreed upon by the
Trustee.

Section 9.  SUCCESSOR TRUSTEE.

     (a)  APPOINTMENT.  If the office of Trustee becomes vacant
for any reason, the Sponsor may in writing appoint a successor
trustee under this Agreement.  The successor trustee shall have
all of the rights, powers, privileges, obligations, duties,
liabilities, and immunities granted to the Trustee under this
Agreement.  The successor trustee and predecessor trustee shall
not be liable for the acts or omissions of the other with
respect to the Trust.

     (b)  ACCEPTANCE.  When the successor trustee accepts its
appointment under this Agreement, title to and possession of
the Trust assets shall immediately vest in the successor
trustee without any further action on the part of the
predecessor trustee.  The predecessor trustee shall execute all
instruments and do all acts that reasonably may be necessary or
reasonably may be requested in writing by the Sponsor or the
successor trustee to vest title to all Trust assets in the
successor trustee or to deliver all Trust assets to the
successor trustee.

     (c)  CORPORATE ACTION.  Any successor of the Trustee or
successor trustee, through sale or transfer of the business or
trust department of the Trustee or successor trustee, or
through reorganization, consolidation, or merger, or any
similar transaction, shall, upon consummation of the
transaction, become the successor trustee under this Agreement.

Section 10.  TERMINATION.

This Agreement may be terminated at any time by the Sponsor
upon sixty (60) days' notice in writing to the Trustee.  On the
date of the termination of this Agreement, the Trustee shall
forthwith transfer and deliver to such individual or entity as
the Sponsor shall designate, all cash and assets then
constituting the Trust.  If, by the termination date, the
Sponsor has not notified the Trustee in writing as to whom the
assets and cash are to be transferred and delivered, the
Trustee may bring an appropriate action or proceeding for leave
to deposit the assets and cash in a court of competent
jurisdiction.  The Trustee shall be reimbursed by the Sponsor
for all costs and expenses of the action or proceeding
including, without limitation, reasonable attorneys' fees and
disbursements.

Section 11.  RESIGNATION, REMOVAL, AND TERMINATION NOTICES.

subject, however, to the provisions of this Agreement relating
to amendment, modification, and termination thereof.

Section 13.  AMENDMENT OR MODIFICATION.

This Agreement may be amended or modified at any time and from
time to time only by an instrument executed by both the Sponsor

Agreement shall inure to the benefit of, and shall bind, the
successors and assigns of the respective parties.

     (e)  PARTIAL INVALIDITY.  If any term or provision of this

or unenforceable, shall not be affected thereby, and each term
and provision of this Agreement shall be valid and enforceable
to the fullest extent permitted by law.

     (f)  SECTION HEADINGS.  The headings of the various
sections and subsections of this Agreement have been inserted
only for the purposes of convenience and are not part of this
Agreement and shall not be deemed in any manner to modify,

Telephone exchange hours via a Fidelity Representative are 8:30

is open.  Exchanges via the Internet and Fidelity's voice
response system are intended to be available virtually 24 hours
a day.

FIRSCO reserves the right to change these exchange guidelines
at its discretion.

Note:  The NYSE's normal closing time is 4:00 p.m. (ET); in the
event the NYSE alters its closing time, all references below to

     before 4:00 p.m. (ET), it will receive that day's trade
     date.  Calls received after 4:00 p.m. (ET) will be
     processed on a next business day basis.

     received after 4:00 p.m. (ET) will be processed as if
     received on the following business day.  The Company Stock
     is sold on the business day following the call and the
     subsequent purchase into mutual funds will take place

     take place three (3) business days later.  This allows for
     settlement of the stock trade at the custodian and the
     corresponding transfer of assets to Fidelity.
    
IV.  Exchange Restrictions

     Participants will not be permitted to make direct
     transfers from the Managed Income Portfolio into a
     competing fund.  Participants who wish to exchange from

     OPERATIONAL GUIDELINES FOR NON-FIDELITY MUTUAL FUNDS
 
PRICING
By 7:00 p.m. Eastern Time ("ET") each Business Day, the Non-
Fidelity Mutual Fund Vendor (Fund Vendor) will input the
following information ("Price Information") into the Fidelity
Participant Recordkeeping System ("FPRS") via the remote
access price screen that Fidelity Investments Institutional
Operations Company, Inc.  ("FIIOC"), an affiliate of the
Trustee, has provided to the Fund Vendor:  (1) the net asset
value for each Fund at the Close of Trading, (2) the change
in each Fund's net asset value from the Close of Trading on
the prior Business Day, and (3) in the case of an income fund
or funds, the daily accrual for interest rate factor ("mil
rate").  FIIOC must receive Price Information each Business
Day (a "Business Day" is any day the New York Stock Exchange
is open).  If on any Business Day the Fund Vendor does not
provide such Price Information to FIIOC, FIIOC shall pend all
associated transaction activity in the Fidelity Participant
Recordkeeping System ("FPRS") until the relevant Price
Information is made available by Fund Vendor.
 
TRADE ACTIVITY AND WIRE TRANSFERS
By 7:00 a.m. ET each Business Day following Trade Date
("Trade Date plus One"), FIIOC will provide, via facsimile,
to the Fund Vendor a consolidated report of net purchase or
net redemption activity that occurred in each of the Funds up
to 4:00 p.m. ET on the prior Business Day.  The report will
reflect the dollar amount of assets and shares to be invested
or withdrawn for each Fund.  FIIOC will transmit this report
to the Fund Vendor each Business Day, regardless of
processing activity.  In the event that data contained in the
