                                     PART I

Item 1.        Business

General

         Linear   Technology   Corporation   (together  with  its   consolidated
subsidiaries,  "Linear Technology" or the "Company")  designs,  manufactures and
markets a broad line of standard high performance  linear  integrated  circuits.
Applications for the Company's products include telecommunications, notebook and
desktop computers, video/multimedia,  computer peripherals, cellular telephones,
industrial,  automotive  and process  controls,  network and factory  automation
products and satellites. The Company was organized and incorporated in 1981 by a
management  team with  significant  experience  in the design,  manufacture  and
marketing of linear  circuits.  The Company  competes  primarily on the basis of
performance, functional value, quality, reliability and service.

The linear circuit industry

         Semiconductor  components  are the electronic  building  blocks used in
electronic  systems and  equipment.  These  components  are classified as either
discrete  devices (such as individual  transistors)  or integrated  circuits (in
which a number of  transistors  and other  elements  are combined to form a more
complicated electronic circuit). Integrated circuits ("ICs") may be divided into
two general categories,  digital and linear (or analog).  Digital circuits, such
as memory  devices and  microprocessors,  generally  process  on-off  electrical
signals, represented by binary digits, "1" and "0." In contrast, linear circuits
monitor,  condition,  amplify or transform  continuous analog signals associated
with physical properties, such as temperature, pressure, weight, light, sound or
speed, and play an important role in bridging between real world phenomena and a
variety of electronic  systems.  Linear circuits also provide voltage regulation
and power control to electronic systems, especially in hand-held battery powered
systems.

         According to World Semiconductor Trade Statistics, worldwide monolithic
linear integrated circuit sales,  estimated to be approximately $19.8 billion in
1997, represent approximately 16% of the total integrated circuit market. Linear
Technology  competes  primarily  in the  non-consumer  segment  of the linear IC
market, which was approximately 71% of the total monolithic linear IC market for
1997.

         The Company  believes that several  factors  generally  distinguish the
linear integrated circuit business from the digital circuit business, including:

                  Importance  of  Individual  Design  Contribution.  The Company
           believes that the  creativity of  individual  design  engineers is of
           particular importance in the linear circuit industry. The design of a
           linear integrated  circuit  generally  involves a greater variety and
           less repetition of circuit elements than digital design. In addition,
           the interaction of linear circuit elements is complex,  and the exact
           placement  of  these  elements  in the  circuit  is  critical  to the
           circuit's precision and performance.  Computer-aided  engineering and
           design  tools for linear  circuits  are not as  accurate  in modeling
           circuits as those tools used for  designing  digital  circuits.  As a
           result,  the contributions of a relatively small number of individual
           design engineers are generally of greater importance in the design of
           linear circuits than in the design of digital circuits.

                  Smaller Capital Requirements.  Digital circuit design attempts
           to minimize  device size and  maximize  speed by  increasing  circuit
           densities.  The process  technology  necessary for increased  density
           requires very expensive  wafer  fabrication  equipment.  In contrast,
           linear circuit  design  focuses on precise  matching and placement of
           circuit  elements,  and linear  circuits  often require large feature
           sizes to achieve precision and high voltage  operation.  Accordingly,
           the linear circuit  manufacturing  process generally requires smaller
           initial capital expenditures, particularly for photomasking equipment
           and  clean  room  facilities,   and  less  frequent   replacement  of
           manufacturing equipment because the equipment has, to date, been less
           vulnerable to technological obsolescence.

                  Market Diversity;  Relative Pricing Stability.  Because of the
           varied  applications  for linear  circuits,  manufacturers  typically
           offer a greater  variety of device types to a more  diverse  group of
           customers, who typically have smaller volume requirements per device.
           As a result,  linear circuit

                                       2
<PAGE>

           manufacturers  are often less dependent upon  particular  products or
           customers,  linear circuit markets are generally more fragmented, and
           competition  within  those  markets  tends to be more  diffused.  The
           Company  believes that  competition  in the linear  circuit market is
           particularly  dependent upon performance,  functional value, quality,
           reliability  and service.  As a result,  linear  circuit  pricing has
           generally been more stable than most digital circuit pricing.

                  Less Japanese And Other Asian Competition.  To date,  Japanese
           and other Asian  firms have  concentrated  their  efforts on the high
           volume digital and consumer  linear  markets,  as opposed to the high
           performance end of the linear circuit market served by the Company.

         The Semiconductor Industry. The semiconductor industry is characterized
by  rapid  technological  change,  price  erosion,   cyclical  market  patterns,
occasional  shortages  of  materials,   capacity   constraints,   variations  in
manufacturing  efficiencies,  and significant expenditures for capital equipment
and  product  development.  Furthermore,  new product  introductions  and patent
protection of existing products are critical factors for future sales growth and
sustained profitability. Although the Company believes that the high performance
segment  of the  linear  circuit  market is  generally  less  affected  by price
erosion,  cyclical  market  patterns and  significant  expenditures  for capital
equipment  and product  development  than other  semiconductor  market  sectors,
future operating results may reflect  substantial period to period  fluctuations
due to these or other factors.

         Although  the  Company   believes  that  it  has  the  product   lines,
manufacturing  facilities and technical and financial  resources for its current
operations,  sales and profitability can be significantly  affected by the above
and other factors.  Additionally, the Company's common stock could be subject to
significant  price  volatility  should  sales and/or  earnings  fail to meet the
expectations of the investment community.

Products and markets

         Linear  Technology  produces a wide range of products  for a variety of
customers  and  markets.  The Company  emphasizes  standard  products to address
larger  markets and to reduce the risk of  dependency  upon a single  customer's
requirements.  The Company  targets the high  performance  segment of the linear
circuit market.  "High  performance" is characterized by higher precision,  both
high power or micropower,  higher speed, more subsystem  integration on a single
chip and many other special  features.  The Company focuses virtually all of its
design efforts on proprietary  products which, at the time of introduction,  are
original designs by the Company offering unique characteristics  differentiating
them from those offered by  competitors.  For fiscal 1998,  sales of proprietary
products were approximately 95% of the Company's net sales.

         Although the types and mix of linear products vary by application,  the
principal product categories are as follows:

         Amplifiers - These circuits  amplify the voltage or output current of a
device. The amplification  represents the ratio of the output voltage or current
to the input voltage or current.  The most widely used device is the operational
amplifier due to its versatility and precision.

         High Speed  Amplifiers - These  amplifiers are used to amplify  signals
above  5MHz for  applications  such as  video,  fast data  acquisition  and data
communication.

         Voltage Regulators - Voltage regulators control the voltage of a device
or circuit at a specified level. This category of product consists  primarily of
two types,  the linear  regulator  and the switch  mode  regulator.  Switch mode
regulators  are also used to  convert  voltage up or down  within an  electronic
system for power management.

         Voltage  References - These  circuits  serve as  electronic  benchmarks
providing  a constant  voltage for system  usage.  Precision  references  have a
constant output independent of input, temperature changes or time.

         Interface  -  Interface  circuits  act as an  intermediary  to transfer
signals  between  or  within  electronic  systems.  These  circuits  are used in
computers, modems, instruments and remote data acquisition systems.

                                       3
<PAGE>

         Data Converters - These circuits  change linear  (analog)  signals into
digital  signals,  or vice versa,  and are often referred to as data acquisition
subsystems, A/D converters and D/A converters. The accuracy and speed with which
the analog  signal is converted to its digital  counterpart  is considered a key
characteristic for these devices.

         Other  -  Other   linear   circuits   include   buffers,   comparators,
sample-and-hold devices, and switched capacitor filters, which are used to limit
and/or  manipulate  signals in such  applications as cellular  telephones,  base
stations, navigation system instrumentation and detection circuitry.

         Linear   circuits   are  used  in   various   applications   including:
telecommunications,  notebook and desktop computers, video/multimedia,  computer
peripherals,  cellular telephones,  industrial, automotive and process controls,
network and factory automation products and satellites.  The Company focuses its
product development and marketing efforts on high performance applications where
the Company  believes  it can  position  itself  competitively  with  respect to
product performance and functional value.

The following table sets forth,  with respect to each of the market areas served
by the Company, examples of specific end applications of the Company's products.

Marketing and customers

         The Company markets its products worldwide, primarily through a network
of independent sales  representatives and electronics  distributors,  to a broad
range of  customers  in  diverse  industries.  In certain  limited  geographical
markets the Company has direct  sales  staff.  The Company  sells to over 15,000
Original Equipment  Manufacturer  (OEM) customers,  many of which purchase on an
individual purchase order basis,  rather than pursuant to long-term  agreements.
The Company's two largest domestic  distributors  accounted for 25%, 26% and 20%
of net sales for fiscal 1998, 1997 and 1996, respectively.  Distributors are not
end  customers,  but rather  serve as a channel of sale to many end users of the
Company's  products.  No other distributor or customer accounted for 10% or more
of net sales for fiscal 1998, 1997 or 1996.

         The Company has agreements with 16 independent sales representatives in
the United States and 2 in Canada. Commissions are paid to sales representatives
upon shipments  either  directly from the Company or through  distributors.  The
Company has agreements with 5 independent  distributors in the United States,  2
in Canada, 18 in Europe, 3 in Japan, 2 each in Korea, Hong Kong and Taiwan,  and
1 each in Singapore, South Africa, Philippines, India, Israel and Australia. The
Company's  distributors purchase the Company's products for resale to customers.
Additionally,  domestic  distributors  often sell competitors'  products.  Under
certain  agreements,  the Company's domestic  distributors are entitled to price
rebates on  inventory  if the  Company  lowers the prices of its  products.  The
agreements also generally permit  distributors to exchange up to 5% of purchases
semi-annually.  See  Note  1  of  Notes  to  Consolidated  Financial  Statements
incorporated  by  reference to Exhibit  13.1 of this Form 10-K,  which  contains
certain   information   included  in  the   Company's   1998  Annual  Report  to
Shareholders.

         The  Company's   sales   organization  is  divided  into  domestic  and
international  regions, with sales managers based at the Company's  headquarters
and in the metropolitan areas of Boston, Philadelphia, Raleigh, Chicago, Dallas,
Austin, Houston, Los Angeles, Irvine,  London,  Stockholm,  Dusseldorf,  Munich,
Stuttgart,  Paris,  Singapore,  Tokyo,  Taipei and Seoul. The Company's products
typically require a sophisticated technical sales effort.

         During  fiscal  1998,  1997 and 1996,  export  sales were  primarily to
Europe,  Japan and Asia and  represented  approximately  52%, 49% and 52% of net
sales,  respectively.  Because most of the Company's export sales are billed and
payable in United  States  dollars,  export  sales are  generally  not  directly
subject to fluctuating currency exchange rates. A strengthening of the dollar in
relation to other currencies may,  however,  create pricing  pressure.  Although
export sales are subject to certain control restrictions,  including approval by
the Office of Export Administration of the United States Department of Commerce,
the Company  has not  experienced  any  material  difficulties  relating to such
restrictions.

         The  Company's  backlog of released  and firm orders was  approximately
$64.3  million at June 28, 1998 as compared with $67.0 million at June 29, 1997.
In addition to its backlog, the Company had $29.1 million of product sold to and
held by domestic  distributors  at June 28, 1998 as compared to $25.9 million at
June 29, 1997. Generally,  shipments to domestic distributors are not recognized
as sales  until the  distributor  has sold the  products to its  customers.  The
Company  expects to ship virtually all of its backlog as of June 28, 1998 during
fiscal 1999. The Company defines  backlog as consisting of distributor  stocking
orders and OEM orders for which a delivery schedule

                                       6
<PAGE>

has been specified by the OEM customer for product  shipment  within six months.
Although the Company receives volume purchase orders,  most such purchase orders
are cancelable by the customer without  significant  penalty.  Lead time for the
release  of  purchase  orders  depends  upon  the  scheduling  practices  of the
individual  customer,  so the rate of booking  new orders  varies  from month to
month. The ordering practices of many semiconductor customers has shifted from a
practice of placing orders with delivery dates  extending over several months to
the practice of placing orders with shorter delivery dates.  Also, the Company's
agreements  with  certain  distributors  provide for limited  price  protection.
Consequently,  the  Company  does not  believe  that its  backlog at any time is
necessarily representative of actual sales for any succeeding period.

         In the operating  history of the Company,  seasonality  of business has
not been a material  factor,  although the results of  operations  for the first
fiscal quarter of each year are impacted  slightly by customary summer holidays,
particularly in Europe.

         The Company warrants that its products,  until they are incorporated in
other  products,  are free from defects in workmanship and materials and conform
to the Company's published specifications.  Warranty expense has been nominal to
date.

Manufacturing

         The  Company's  wafer  fabrication  and  manufacturing  facilities  are
located  at  its  headquarters  in  Milpitas,   California,  and  at  its  wafer
fabrication  plant in Camas,  Washington.  Each  facility  was built to  Company
specifications to support a number of sophisticated  process technologies and to
satisfy rigorous quality assurance and reliability requirements of United States
military  specifications  and  major  worldwide  OEM  customers.  The  Company's
Milpitas and Singapore facilities have received ISO9001 certification.

         The Company's wafer fabrication  facility located in Camas,  Washington
commenced manufacturing  operations in the second half of fiscal 1997. The Camas
wafer  fabrication  facility is used to produce six-inch diameter wafers for use
in the  production  of the  Company's  devices;  the  Company's  Milpitas  wafer
fabrication plant produces four-inch diameter wafers. The Company currently uses
similar manufacturing  processes in both its Milpitas and Camas facilities.  The
Company plans to build another fabrication facility near its existing facilities
in California  during fiscal 1999. This new fabrication plant is not expected to
be completed  until fiscal 2000.  The Company also has the ability to expand the
manufacturing  capacity of the Camas facility as needed to meet its future wafer
requirements.

         The Company's  basic process  technologies  include high speed bipolar,
high  gain,  low  noise   bipolar,   silicon  gate   complementary   metal-oxide
semiconductor   ("CMOS")  and  BiCMOS  processes.   The  Company  also  has  two
proprietary complementary bipolar processes. The Company's bipolar processes are
typically used in linear circuits where high voltages,  high power, low noise or
effective  component matching is necessary.  The Company's  proprietary  silicon
gate CMOS  processes  provide  switch  characteristics  required for many linear
circuit  functions,  as well as an efficient  mechanism for combining linear and
digital  circuits on the same chip.  The Company's CMOS processes were developed
to  address  the  specific   requirements  of  linear  circuit  functions.   The
complementary  bipolar  processes  were developed to address higher speed analog
functions.  The  Company's  basic  processes  can be  combined  with a number of
adjunct processes to create a diversity of IC components. The accompanying chart
provides a brief overview of the Company's IC process capabilities:

         The Company  emphasizes  quality and  reliability  from initial product
design through  manufacturing,  packaging and testing. The Company's design team
focuses on fault  tolerant  design and optimum  location of circuit  elements to
enhance reliability.  Linear Technology's wafer fabrication facilities have been
designed to minimize wafer handling and the impact of operator error through the
use of  microprocessor-controlled  equipment.  The Company has obtained  Defense
Supply Center,  Columbus (DSCC) qualification to participate in high reliability
JAN38510 (class B) military business.  The Company has also received Jan Class S
Microcircuit  Certification,  which enables the Company to manufacture  products
intended  for use in space or for critical  applications  where  replacement  is
extremely difficult or impossible and where reliability is imperative.

         The  Company is  certified  to comply  with the  ISO9001  international
quality standard. This certification covers the Company's design,  manufacturing
and  service  organizations  and  is an  important  standard  especially  in the
European  marketplace.   The  Company  has  received   MIL-PRF-38535   Qualified
Manufacturers Listing (QML) certification for military products from DSCC.

         Processed wafers are sent to either the Company's  assembly facility in
Penang,  Malaysia  or to offshore  independent  assembly  contractors  where the
wafers are separated into individual circuits and packaged.  The Penang facility
opened in October 1994 and services  approximately  two-thirds  of the Company's
assembly requirements for plastic packages.  Significant assembly subcontractors
used by the Company are Carsem(M) Sdn,  Carsem  Semiconductor  Sdn and Unisem(M)
Sdn located in Malaysia. The Company also maintains domestic assembly operations
to satisfy  particular  customer  requirements,  especially  those for  military
applications, and to provide rapid turnaround for new product development.

                                       8
<PAGE>

         After  assembly,  most  products  are sent to the  Company's  Singapore
facility for final testing,  inspection and packaging as required. Some products
are returned to Milpitas for the same back-end processing.

         Linear  Technology from time to time has experienced  competition  from
other manufacturers seeking assembly of circuits by independent contractors. The
Company  currently  believes that alternative  foreign assembly sources could be
obtained without significant interruption.  Foreign assembly is subject to risks
normally  associated  with  foreign  operations,   including  changes  in  local
governmental  policies,  currency  fluctuations,  transportation  delays and the
imposition of export controls or increased import tariffs.

         From time to time  certain  materials,  including  silicon  wafers  and
plastic molding  compounds,  have been in short supply.  To date the Company has
experienced no delays in obtaining raw materials  which have adversely  affected
production.  As  is  typical  in  the  industry,  the  Company  must  allow  for
significant lead times in delivery of its materials.

         Manufacturing of individual  products,  from wafer fabrication  through
final  testing,  may take from ten to sixteen  weeks.  Since the Company sells a
wide  variety of device  types,  and  customers  typically  expect  delivery  of
products within a short period of time following order, the Company  maintains a
substantial work-in-process and finished goods inventory.

         Based on its anticipated production requirements,  the Company believes
it will have  sufficient  available  resources  and  manufacturing  capacity for
fiscal 1999.

Patents, licenses and trademarks

         The Company has been awarded 91 United States patents, and has filed 66
additional patent applications. Although the Company believes that these patents
and patent applications may have value, the Company's future success will depend
primarily  upon the technical  abilities and creative  skills of its  personnel,
rather than on its patents.

         As is common in the  semiconductor  industry,  the Company has at times
been notified of claims that it may be infringing  patents issued to others.  If
it appears  necessary or  desirable,  the Company may seek  licenses  under such
patents,  although there can be no assurance that all necessary  licenses can be
obtained by the Company on acceptable terms.

         In  addition,  from time to time the Company may  negotiate  with other
companies  to license  patents,  products or process  technology  for use in its
business.

Government sales

         The Company currently has no material U.S. Government contracts.

Competition

         Linear  Technology  competes  in the high  performance  segment  of the
linear  market.  The  Company's   competitors  include  Analog  Devices,   Inc.,
Burr-Brown  Corporation,   Maxim  Integrated  Products,  Inc.,  Motorola,  Inc.,
National Semiconductor Corporation and Texas Instruments, Inc. Competition among
manufacturers  of linear  integrated  circuits  is  intense,  and certain of the
Company's  competitors  may have  significantly  greater  financial,  technical,
manufacturing and marketing  resources than the Company.  The principal elements
of  competition  include  product  performance,  functional  value,  quality and
reliability, technical service and support, price, diversity of product line and
delivery  capabilities.  The Company believes it competes favorably with respect
to these factors,  although it may be at a disadvantage  in comparison to larger
companies with broader product lines and greater  technical  service and support
capabilities.

                                       9
<PAGE>

Research and development

         The  Company's  ability to compete  depends in part upon its  continued
introduction of technologically  innovative  products on a timely basis.  Linear
Technology's  product  development  strategy emphasizes a broad line of standard
products to address a diversity of customer applications. The Company's research
and development  efforts are directed primarily at designing and introducing new
products  and,  to a  lesser  extent,  developing  new  processes  and  advanced
packaging.

         As of June 28,  1998,  the  Company  had 156  employees  engaged in new
product design at its Milpitas  facility.  In addition,  at fiscal year end, the
Company had 12 employees at its  Singapore  design  center,  18 employees at its
Boston design center and 9 employees at its new Colorado design center opened in
fiscal 1997.

         For  the  fiscal  years  1998,   1997  and  1996,   the  Company  spent
approximately $46.2 million, $35.4 million and $31.1 million,  respectively,  on
research and development.

Environmental regulation

         Federal,  state  and local  regulations  impose  various  environmental
controls on the storage,  use,  discharge and disposal of certain  chemicals and
gases used in  semiconductor  processing.  The  Company's  facilities  have been
designed to comply with these  regulations,  and the Company  believes  that its
activities  conform  to present  environmental  regulations.  Increasing  public
attention has, however,  been focused on the environmental impact of electronics
manufacturing  operations.  While the  Company to date has not  experienced  any
materially adverse business effects from environmental regulations, there can be
no assurance  that changes in such  regulations  will not require the Company to
acquire costly remediation  equipment or to incur substantial expenses to comply
with such  regulations.  Any failure by semiconductor  companies,  including the
Company, to control the storage,  use or disposal of, or adequately restrict the
discharge  of  hazardous  substances  could  also  subject  them to  significant
liabilities.

Employees

         As of June 28, 1998, the Company had 2,155 employees,  including 159 in
marketing  and sales,  448 in  research,  development  and  engineering  related
functions,  1,470  in  manufacturing  and  production,  and  78  in  management,
administration  and finance.  The Company's success depends upon a number of key
employees,  the loss of whom could  adversely  impact the  Company.  The Company
believes  that its future  success will depend in large part upon its ability to
attract,  retain and motivate highly skilled employees.  In the San Jose/Silicon
Valley area, where the Company's principal  facilities are located,  competition
for such employees is intense.

         The Company has never had a work stoppage, no employees are represented
by a labor organization,  and the Company considers its employee relations to be
good.

</TABLE>

Net sales were a record  $484.8  million in fiscal 1998, an increase of 28% over
net sales of  $379.3  million  in fiscal  1997.  The  increase  in net sales was
primarily due to an increase in unit shipments,  while the average selling price
for the  Company's  products  declined  slightly  during the year.  The  Company
experienced   strong  sales  growth  in  each  of  its  major  end  markets  and
particularly in the  communications  area which represented 32% of net sales, up
from approximately 30% in fiscal 1997.  Geographically,  the Company experienced
broad sales growth with U.S. sales up 21% and international sales (export sales)
up 34% over fiscal 1997.  International  sales  represented 52% of net sales, up
from 49% in fiscal 1997, and were lead by a strong  European  market where sales
increased 38% over the prior year.  Sales to Japan and Rest of World,  primarily
Pacific Rim  countries,  increased 24% and 37%,  respectively,  over fiscal 1997
despite the economic and financial  difficulties  experienced by Japan and other
countries  in this  region.  However,  as  discussed  more fully  under  Factors
Affecting Future Operating Results below, as fiscal 1998 concluded the Company's
incoming order rate began to slow as customers either experienced a softening in
end customer demand or took advantage of lower supplier lead times.  The Company
currently anticipates that this will cause fiscal 1999 to start with lower sales
volume than the fourth quarter of fiscal 1998.

Net sales of $379.3  million in fiscal 1997 were  generally  flat as compared to
net sales of $377.8  million in fiscal  1996.  Average  selling  prices and unit
volumes for fiscal 1997 were generally unchanged as compared to fiscal 1996. Net
sales in fiscal 1996 reflected a period of  significant  sales growth that began
to decelerate for the Company and much of the semiconductor  industry during the
fourth quarter of fiscal 1996.  Excess inventory levels in end customer channels
entering  fiscal 1997 lead to generally flat quarterly  sequential  sales growth
until the second half of the fiscal  year when end  customer  channel  inventory
levels declined.

International  sales  represented  49% and 52% of net sales in  fiscal  1997 and
1996,  respectively.  International  sales declined  slightly in fiscal 1997 due
primarily  to lower sales to the Japanese  market after a period of  significant
sales growth in Japan in fiscal 1996.  This decline was  partially  offset by an
increase in sales to the European market.

Gross profit was $347.0 million or 71.6% of net sales in fiscal 1998. The slight
increase in gross profit as a percentage of sales as compared to 71.1% in fiscal
1997 was due  primarily  to the  absorption  of fixed costs over a larger  sales
base, lower costs from favorable exchange rates and manufacturing  efficiencies.
This was partially  offset by slightly lower average selling prices, a change in
product mix and higher costs  associated with the ramp-up of the Company's newer
fabrication  facility in Camas,  Washington.  However, the negative gross margin
impact from the Camas facility  peaked in the second quarter of fiscal 1998 and,
sequentially,  the facility  began to have a positive  impact on gross margin in
the third quarter of fiscal 1998 due to higher production volumes.

                                  Exhibit 13.1-3

<PAGE>

Gross profit as a percentage of sales of 71.1% in fiscal 1997 fell slightly from
71.7% of net sales in fiscal 1996.  This  decrease was due primarily to start-up
costs for the Company's wafer fabrication plant in Camas, Washington. Production
commenced at the Camas facility during the fourth quarter of fiscal 1997.

Research and development ("R&D") expenses were $46.2 million,  $35.4 million and
$31.1  in  fiscal  1998,  1997 and  1996 or  9.5%,  9.3% and 8.2% of net  sales,
respectively.  The  increase in R&D  expenses in fiscal 1998 as compared to 1997
was due primarily to an increase in staffing,  particularly  design  engineering
personnel,  an  increase  in  profit  sharing  costs  and  higher  spending  for
development  mask sets and test  wafers.  The increase in R&D expenses in fiscal
1997 over 1996 was due to an increase in design and test engineering  personnel,
an increase  in spending  for  development  mask sets and the  addition of a new
design center in Colorado Springs, Colorado.

Selling,  general and administrative ("SG&A") expenses were $53.3 million, $45.7
million and $49.1 million or 11.0%, 12.1% and 13.0% of net sales in fiscal 1998,
1997 and 1996,  respectively.  The increase in SG&A expenses in fiscal 1998 over
1997 was due primarily to an increase in staffing, particularly sales personnel,
an increase in commissions and profit sharing costs and higher legal costs.  The
increase in legal costs is primarily due to  intellectual  property  suits where
the Company is the  plaintiff.  As a percentage of net sales,  SG&A continued to
decrease in fiscal 1998 as such costs  increased  at a lower rate than net sales
growth.  The decline in SG&A expenses in fiscal 1997 as compared to 1996 was due
primarily to lower legal costs,  sales  commissions and profit sharing  expenses
offset partially by higher advertising costs.

Interest  income in fiscal  1998  increased  47% over 1997 to $23.7  million and
increased 22% in fiscal 1997 to $16.1 million from $13.1 million in fiscal 1996.
The year over year increases were due primarily to the significant  increases in
cash, cash equivalents and short-term  investments which grew $194.5 million and
$121.0  million in fiscal 1998 and 1997,  respectively.  In concert with overall
stable interest rates in the domestic financial  markets,  the Company's average
rate of return in fiscal 1998 was generally flat as compared to fiscal 1997. The
average rate of return in fiscal 1997 was slightly lower than fiscal 1996 due to
lower short-term interest rates.

The  Company's  effective tax rate was 33.3 % in fiscal 1998 and 34.3% in fiscal
1997 and  1996.  The  lower tax rate in  fiscal  1998 is due to an  increase  in
business  activity and assets employed  outside of California  where the Company
experiences lower state tax rates and an increase in tax-exempt interest income.

Factors Affecting Future Operating Results

Except for historical information contained herein, the matters set forth in the
Annual  Report,  including  the  statements  in the  following  paragraphs,  are
forward-looking statements that are dependent on certain risks and uncertainties
including such factors,  among others, as the timing,  volume and pricing of new
orders  received  and  shipped  during  the  quarter,   timely  ramp-up  of  new
facilities,  the timely  introduction  of new processes  and  products,  general
conditions in the world  economy,  the market for the Company's  goods and other
factors described below.

The Company  achieved  record  sales and  earnings in fiscal 1998 and the fourth
quarter of fiscal 1998.  However,  during the fourth quarter demand weakened for
the Company's products resulting in a decrease in the Company's order backlog as
compared with the third quarter of fiscal 1998. The lower order activity appears
to be industry-wide  and has resulted from several factors  including  prolonged
weakness  in the Asian  markets,  slowdown  in the  computer  industry  and,  in
response,  a delay in orders as customers  took advantage of lower supplier lead
times. As a result, during the first quarter of fiscal 1999, the Company expects
quarterly  revenues  and  earnings to decline 10% to 15%  sequentially  from the
fourth quarter of fiscal 1998.

During fiscal 1997, the Company received an extension of its tax holiday for its
Singapore  operations  through  September 1999. An increase in business activity
and assets employed outside of California and an increase in tax-exempt interest
income  resulted  in a lower  effective  tax rate in fiscal  1998 as compared to
fiscal 1997. The Company  expects this trend to continue  resulting in a further
decline in its effective tax rate to the 32% to 32.5% range for fiscal 1999.

The Company plans to build another fabrication facility in California and expand
existing manufacturing facilities during fiscal 1999. As a result, total capital
expenditures for fiscal 1999 are expected to increase  significantly over fiscal
1998. The new fabrication  facility is not expected to be completed until fiscal
2000.

Past  performance  of  the  Company  may  not  be a  good  indicator  of  future
performance  due  to  factors  affecting  the  Company,  its  competitors,   the
semiconductor  industry and the overall economy.  The semiconductor  industry is
characterized  by rapid  technological  change,  price erosion,  cyclical market
patterns,  periodic oversupply  conditions,  occasional  shortages of materials,
capacity  constraints,  variation in manufacturing  efficiencies and significant
expenditures for capital  equipment and product  development.  Furthermore,  new
product  introductions  and patent  protection of existing products are critical
factors for future sales growth and sustained profitability.

Although  the  Company  believes  that it has the product  lines,  manufacturing
facilities  and technical and  financial  resources for its current  operations,
sales and  profitability  can be  significantly  affected by the above and other
factors.   Additionally,   the  Company's  common  stock  could  be  subject  to
significant   price  volatility  should  sales  and/or  earnings  fail  to  meet
expectations of the investment community.

Liquidity and Capital Resources

At June 28, 1998,  cash,  cash  equivalents and short-term  investments  totaled
$637.9  million,  an  increase  of  $194.5  million  or 43.9%  over  cash,  cash
equivalents  and  short-term  investments of $443.4 million at the end of fiscal
1997.

The issuance of common stock under stock option plans  provided $60.7 million in
proceeds and tax benefits in fiscal 1998 as compared to $40.8  million in fiscal
1997. The proceeds from stock issuances increased by $8.1 million in fiscal 1998
due to increases in the number of shares  exercised and average  exercise price.
The tax benefit from stock  option  transactions  increased by $11.8  million in
fiscal 1998 due to  increases  in shares  exercised  and  taxable  gains on sale
resulting  from higher  market prices for the Company's  stock.  Generally,  the
Company  receives a tax  deduction  for the gain the employee  recognizes on the
exercise  of a  nonqualified  stock  option and  records  this tax benefit as an
increase in common stock and a reduction in current income taxes payable. During
fiscal 1998, the Company  purchased  1,002,500 shares of its common stock on the
open market for $56.4 million.

The  Company's  capital  expenditures  in  fiscal  1998  totaled  $24.4  million
primarily  for the  purchase  of  machinery  and  equipment  for  the  Company's
fabrication,  test and assembly facilities. The Company expects that fiscal 1999
expenditures for capital assets will increase significantly as the Company plans
to build another  fabrication  facility in California  and expand certain of its
manufacturing facilities.

Cash  dividends  of $0.24  per share  totaling  $18.3  million  were paid by the
Company in fiscal  1998 as compared to $0.20 per share  totaling  $15.0  million
fiscal 1997. In July 1998, the Company's  Board of Directors  announced that the
quarterly  cash  dividend was increased to $0.07 per share from $0.06 per share.
Future dividends will be based on quarterly financial performance.

The Company's cash equivalents and short-term  investments are subject to market
risk,  primarily  interest-rate  and credit risk. The Company's  investments are
managed by outside professional managers within investment guidelines set by the
Company.  Such guidelines include security type, credit quality and maturity and
are intended to limit market risk by  restricting  the Company's  investments to
high quality debt instruments with relatively short-term maturities.  Based upon
the weighted average  duration of the Company's  investments at June 28, 1998, a
1% (100 basis points)  increase in short-term  interest rates would result in an
unrealized  loss  in  market  value  of  the  Company's   investments   totaling
approximately $5.5 million.  However,  because the Company's debt securities are
carried as available for sale, no gains or losses are  recognized by the Company
due to  changes in  interest  rates  unless  such  securities  are sold prior to
maturity.  The Company generally holds securities until maturity and carries the
securities at amortized cost, which approximates fair market value.

At the end of fiscal 1998,  working  capital was $645.2  million and the Company
had no  long-term  debt.  For the past several  years the Company has  generally
satisfied its liquidity  needs through cash  generated  from  operations and its
existing cash and investment balances.  Given its strong financial condition and
performance,  the Company plans to continue to finance its capital needs through
these internal sources for the foreseeable future.

Year 2000

The Company has identified its internal  computer  hardware devices and software
applications  that  require  modification  to become year 2000  compliant.  Such
devices and  applications  are  primarily  third  party  products  with  minimal
customization.  The Company is currently  working  with these  vendors and other
consultants to ascertain and resolve the potential problems  associated with the
processing of date sensitive information.  Based on preliminary information, the
Company believes that its internal  computer systems will be year 2000 compliant
and that the risk of major disruption from these systems due to year 2000 issues
is minimal.  However, the Company could be negatively affected to the extent its
major suppliers, vendors and customers have not successfully addressed year 2000
issues and intends to contact  critical  third parties to assess this  exposure.
There can be no assurance  that such parties will be year 2000  compliant or, in
any event,  that the  Company  will not be  negatively  affected  from year 2000
issues.  The Company does not expect the cost of implementation for its internal
computer systems to have a material impact on the Company's  financial  position
or results of operations.

Basis of Presentation
The Company's  fiscal year ends on the Sunday nearest June 30. Fiscal 1998, 1997
and  1996  were  52  week  periods.  The  accompanying   consolidated  financial
statements include the accounts of the Company and its wholly-owned subsidiaries
after  elimination of all significant  inter-company  accounts and transactions.
Accounts  denominated in foreign  currencies have been translated using the U.S.
dollar as the functional currency.

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.

Cash Equivalents and Short-Term Investments
Cash equivalents are highly liquid investments with original maturities of three
months or less.  Investments  with  maturities  over three months at the time of
purchase are classified as short-term investments.

At June 28, 1998 and June 29, 1997,  all of the  Company's  investments  in debt
securities were classified as available-for-sale, which means that, although the
Company  principally  holds  securities  until maturity,  they may be sold under
certain  circumstances.  The debt securities are carried at amortized cost which
approximates  fair market value. At June 28, 1998 and June 29, 1997, the Company
held no equity securities.

Concentrations of Credit Risk and Off Balance Sheet Risk
The Company's  investment  policy  restricts  investments to high credit quality
investments  with a  maturity  of  three  years or less and  limits  the  amount
invested  with any one issuer.  Concentrations  of credit  risk with  respect to
accounts  receivable are generally not  significant  due to the diversity of the
Company's  customers and geographic  sales areas.  The Company  performs ongoing
credit   evaluations  of  its  customers'   financial   condition  and  requires
collateral, primarily letters of credit, as deemed necessary.

The Company's two largest domestic  distributors  accounted for 25%, 26% and 20%
of net sales for fiscal 1998, 1997 and 1996, respectively.  Distributors are not
end  customers,  but rather  serve as a channel of sale to many end users of the
Company's  products.  No other distributor or customer accounted for 10% or more
of net sales for fiscal 1998, 1997 and 1996.

The Company's assets,  liabilities and cash flows are predominately  U.S. dollar
denominated,  including those of its foreign operations.  However, the Company's
foreign  subsidiaries  have certain assets,  liabilities and cash flows that are
subject to foreign  currency risk.  The Company  considers this risk to be minor
and,  for the three  years  ended June 28,  1998,  had not  utilized  derivative
instruments to hedge foreign  currency risk or for any other purpose.  Gains and
losses  resulting from foreign  currency  fluctuations  are recognized in income
currently and were not material for all periods presented.

Inventories
Inventories are stated at the lower of standard cost, which approximates  actual
cost determined on a first-in, first-out basis, or market.

                                Exhibit 13.1-10

<PAGE>

Property, Plant and Equipment
Depreciation and amortization are provided using the  straight-line  method over
the  estimated  useful  lives of the assets (3-7 years for  equipment  and 10-30
years for  buildings  and building  improvements).  Leasehold  improvements  are
amortized  over the shorter of the asset's useful life or the likely term of the
lease.

Deferred Income on Shipments to Distributors
The Company  sells to domestic  distributors  under  agreements  allowing  price
protection   and  right  of  return  on  certain   merchandise   unsold  by  the
distributors. Because of the uncertainty associated with pricing concessions and
future returns,  the Company defers  recognition of such sales and profit in its
financial statements until the merchandise is sold by the domestic distributors.
The Company estimates international  distributor returns and defers a portion of
international distributor sales and profits based on these estimated returns.

Employee Stock Plans
The Company accounts for its employee stock plans in accordance with APB Opinion
No. 25,  "Accounting for Stock Issued to Employees".  The pro-forma  disclosures
required under Statement of Financial  Accounting Standards No. 123, "Accounting
for  Stock-Based   Compensation"  are  included  in  Note  4  to  the  financial
statements.

Net Income Per Share
In fiscal 1998, the Company adopted Statement of Financial  Accounting Standards
No. 128,  Earnings Per Share ("FAS 128"). As required by FAS 128, basic earnings
per share and diluted  earnings  per share have  replaced  primary  earnings per
share previously reported by the Company. Basic earnings per share is based upon
the weighted  average number of shares of common shares  outstanding  during the
period.  Diluted  earnings per share  includes  the dilutive  effect of employee
stock  options  and is  comparable  to  primary  earnings  per share  previously
reported  by the  Company.  All  earnings  per  share  amounts  for the  periods
presented  have been  restated to conform to the  requirements  of FAS 128.  The
following table sets forth the  reconciliation of weighted average common shares
outstanding used in the computation of basic and diluted earnings per share:

Recent Pronouncements
In June 1997, the Financial Accounting Standards Board ("FASB") issued Statement
of Financial  Accounting  Standards No. 130,  "Reporting  Comprehensive  Income"
("FAS 130"). This statement  establishes new rules for the reporting and display
of comprehensive  income and its components.  Components of comprehensive income
include net income and certain transactions that have generally been reported in
the consolidated  statement of shareholders' equity. FAS 130 requires that these
transactions   be  included  with  net  income  and   presented   separately  as
comprehensive  income in the  financial  statements.  The Company is required to
adopt FAS 130 during fiscal 1999. At the time of adoption,  the Company  expects
that comprehensive income will not be materially different from net income.

In June 1997, the FASB issued  Statement of Financial  Accounting  Standards No.
131, "Disclosures About Segments of an Enterprise and Related Information". This
statement  changes the way public  companies  report  segment  information.  The
statement is effective for fiscal years  beginning  after  December 15, 1997 and
will be adopted by the Company for the fiscal year ending June 27, 1999.

In June 1998, the FASB issued  Statement of Financial  Accounting  Standards No.
133, "Accounting for Derivative Investments and Hedging Activities" ("FAS 133").
The  statement  provides  a  comprehensive  and  consistent   standard  for  the
recognition and measurement of derivatives and hedging  activities.  The Company
is  required  to adopt  FAS 133  during  fiscal  2000 and  does not  expect  the
statement to have a significant effect on the Company's operating results.

2. Cash Equivalents and Short-term Investments

The estimated fair values of cash  equivalents  and short-term  investments  are
based on market prices. Investments as of June 28, 1998 were as follows:

3. Lease Commitments
The Company leases certain of its facilities  under  operating  leases,  some of
which have  options to extend the lease  period.  In  addition,  the Company has
entered into  long-term  land leases for the sites of its Singapore and Malaysia
manufacturing facilities.

                                Exhibit 13.1-12

<PAGE>

At June 28,  1998,  the  future  minimum  lease  payments  under  non-cancelable
operating leases having an initial term in excess of one year were approximately
as follows:  fiscal  1999:  $1,582,000;  fiscal 2000:  $1,404,000;  fiscal 2001:
$916,000;   fiscal  2002:  $876,000;  fiscal  2003:  $792,000;  and  thereafter:
$7,373,000.

Total rent expense was  approximately  $2,528,000,  $2,379,000 and $2,015,000 in
fiscal 1998, 1997 and 1996, respectively.

4. Employee Benefit Plans

Stock option plans
The Company has stock option plans under which options to purchase shares of the
Company's  common stock may be granted to employees  and directors at a price no
less than the fair market value on the date of the grant.  At June 28, 1998, the
total authorized number of shares under all plans was 34,500,000. Options become
exercisable  over a  five-year  period  (generally  10% every six  months).  All
options expire ten years after the date of the grant.

In fiscal 1997,  the Board of Directors  approved the  repricing of stock option
grants  totaling  2,510,600  shares  granted during fiscal 1996. In exchange for
these new options,  all vesting  under the  canceled  options was lost and a new
five year vesting period was started.

Option transactions during fiscal 1996, 1997 and 1998 are summarized as follows:

Stock Purchase Plan
The  Company's  stock  purchase  plan  ("ESPP")  permits  eligible  employees to
purchase common stock through payroll deductions at the lower of 85% of the fair
market  value of  common  stock at the  beginning  or the end of each six  month
offering

                                Exhibit 13.1-13

period.  The offering periods commence on approximately  May 1 and November 1 of
each year. At June 28, 1998,  the shares  reserved for issuance  under this plan
totaled  2,100,000 and 1,633,676 shares had been issued under this plan.  During
fiscal 1998, 66,284 shares were issued at a weighted-average price of $43.63 per
share pursuant to this plan.

Stock-Based Compensation
The Company accounts for stock-based compensation in accordance with APB Opinion
No. 25,  "Accounting for Stock Issued to Employees"and  related  Interpretations
("APB  25").  In  accordance  with  APB  25,  the  Company  does  not  recognize
compensation  expense for stock  options and other stock based awards  issued to
employees. However, the dilutive effect of employee stock options is included in
the calculation of diluted earnings per share.

In fiscal 1997, the Company adopted Statement of Financial  Accounting Standards
No. 123, "Accounting for Stock-Based Compensation" ("FAS 123"). FAS 123 attempts
to quantify and measure  currently the potential  future value of employee stock
options and other stock-based awards to employees.  The valuation  techniques it
recommends are highly  subjective and these methods could result in amounts that
differ  significantly from those amounts to be actually incurred.  Consequently,
FAS 123 allows companies to implement the pronouncement in the primary financial
statements  or to disclose  the  pro-forma  effects of FAS 123 in the  financial
statement  footnotes.  The Company  continues to apply APB 25 in accounting  for
stock-based  awards to employees  and to disclose the  pro-forma  effects of FAS
123. Had  compensation  cost for the Company's  stock-based  awards to employees
been  determined  consistent with FAS 123, the Company's net income and earnings
per share would have been reduced to the pro-forma  amounts  indicated below (in
thousands, except per share amounts):

For purposes of the pro-forma  information,  the fair value of each stock option
and ESPP grant is estimated on the date of grant using the Black-Scholes  option
pricing model and the following weighted average assumptions:

</TABLE>
Using the  Black-Scholes  option pricing model, the weighted  average  estimated
fair value of employee stock options  granted in fiscal 1998,  1997 and 1996 was
$31.07,  $20.07  and  $19.85  per  share,  respectively.  The  weighted  average
estimated  fair value of ESPP shares  granted in fiscal 1998,  1997 and 1996 was
$16.93,  $10.14  and $9.95 per  share,  respectively.  For the  purposes  of the
pro-forma  information,  the estimated fair values of the employee stock options
and ESPP shares are amortized to expense using the straight-line method over the
vesting or offering  periods,  which is generally  five years for employee stock
options  and six  months  for ESPP  shares.  The  pro-forma  information  is not
representative  of the pro-forma  effect of the fair value provisions of FAS 123
on the Company's income in future years because pro-forma  compensation  expense
related to grants  made prior to the  implementation  of FAS 123 in fiscal  1996
have not been taken into consideration. Accordingly, the pro-forma effect of FAS
123 will not be fully reflected until fiscal 2000 when the pro-forma effect will
include  compensation expense for stock option grants issued during the previous
five years.

Retirement Plan
The Company has  established a 401(k)  retirement  plan for its  qualified  U.S.
employees.  Profit sharing  contributions  made by the Company to this plan were
approximately  $6,126,000,  $5,038,000 and  $4,864,000 in fiscal 1998,  1997 and
1996, respectively.

from stock option  activity is recorded as a reduction  in current  income taxes
payable and an increase in common stock.

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 assets and liabilities  recorded in the balance sheet
as of June 28, 1998 and June 29, 1997 are as follows:

The  Company's  Singapore  subsidiary  has been  granted a ten-year tax holiday,
which is scheduled to expire in September  1999.  Also,  the Company's  Malaysia
subsidiary  has been  granted a five-year  tax  holiday,  which is  scheduled to
expire in June 2000.

                                Exhibit 13.1-15

<PAGE>

The impact of the Singapore and Malaysia tax holidays was to increase net income
by approximately $5,135,000 ($0.06 per diluted share) in fiscal 1998, $5,002,000
($0.06 per  diluted  share) in fiscal  1997 and  $3,731,000  ($0.05 per  diluted
share) in fiscal  1996.  The Company  does not provide a residual  U.S. tax on a
portion  of  the   undistributed   earnings  of  its   Singapore   and  Malaysia
subsidiaries,  as it is the  Company's  intention  to  permanently  invest these
earnings  overseas.  Should  these  earnings  be  remitted  to the U.S.  parent,
additional U.S. taxable income would be approximately $71,265,000.

REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS


The Board of Directors and Shareholders of Linear Technology Corporation

We  have  audited  the  accompanying   consolidated  balance  sheets  of  Linear
Technology  Corporation  as of June 28,  1998 and June 29,  1997 and the related
consolidated statements of income,  shareholders' equity and cash flows for each
of the three years in the period ended June 28, 1998. These financial statements
are the  responsibility of the Company's  management.  Our  responsibility is to
express an opinion on these financial statements based on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  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 consolidated  financial statements referred to above present
fairly, in all material respects,  the consolidated financial position of Linear
Technology  Corporation at June 28, 1998 and June 29, 1997, and the consolidated
results of its  operations and its cash flows for each of the three years in the
period ended June 28, 1998, in conformity  with  generally  accepted  accounting
principles.
