         Restrictions, if any, imposed upon the transfer of shares:

              Any stockholder, including the heirs, assigns, executors or
         administrators of a deceased stockholder, desiring to sell or transfer
         any stock owned by him or them, shall first offer it to the corporation
         through the Board of Directors, in the manner following:

              He shall notify the directors of his desire to sell or transfer by
         notice in writing, which notice shall contain the price at which he is
         willing to sell or transfer and the name of one arbitrator. The
         Directors shall within thirty (30) days thereafter either accept the
         offer, or by notice to him in writing name a second arbitrator, and
         these two shall name a third. It shall then be the duty of the
         arbitrators to ascertain the value of the stock, and if any arbitrator
         shall neglect or refuse to appear at any meeting appointed by the
         arbitrators, a majority may act in the absence of such arbitrator.

              After the acceptance of the offer, or the report of the
         arbitrators as to the value of the stock, the directors shall have
         thirty days within which to purchase the same at such valuation, but if
         at the expiration of thirty days, the corporation shall not have
         exercised the rights so to purchase, the owner of the stock shall be at
         liberty to dispose of the same in any manner he may see fit.

              No shares of stock shall be sold or transferred on the books of
         the corporation until these provisions have been complied with, but the
         Board of Directors may in any particular instance waive the
         requirement.

         different classes of stock with, if any, the preferences, voting

         each class thereof and any series now established:

              Rights, Preferences, Limitations and Restrictions on Capital

               The Preferred Stock may be issued in one or more series at such
          time or times and for such consideration or considerations as the
          Board of Directors may determine. Each series shall be so designated
          as to distinguish the shares thereof from the shares of all other
          series and classes. Except as to the relative rights and preferences
          referred to in paragraph B below, in respect of any or all of which
          there may be variations between different series, all shares of
          Preferred Stock shall be identical. Different series of Preferred
          Stock shall not be construed to constitute different classes of shares
          for the purpose of voting by classes.

               The Board of Directors is expressly authorized, subject to the
          limitations prescribed by law and the provisions of these Articles of
          Organization, to provide by adopting a vote or votes, a certificate of

          of the Commonwealth of Massachusetts for the issue of the Preferred
          Stock in one or more series, each with such designations, preferences
          and relative, participating, optional or other special rights, and
          qualifications, limitations or restrictions thereof as shall be stated
          in the vote or votes creating such series. The authority of the Board
          of Directors with respect to each such series shall include without
          limitation of the foregoing the right to determine and fix:

               (1) the distinctive designation of such series and the number of
          shares to constitute such series;

<PAGE>   27


               (2) The rate at which dividends on the shares of such series
          shall be declared and paid, or set aside for payment, whether
          dividends at the rate so determined shall be cumulative, and whether
          the shares of such series shall be entitled to any participating or
          other dividends in addition to dividends at the rate so determined,
          and if so on what terms;

               (3) The right, if any, of the corporation to redeem shares of the
          particular series and, if redeemable, the price, terms and manner of
          such redemption;

               (4) The special and relative rights and references, if any, and
          the amount of amounts per share, which the shares of such series shall
          be entitled to receive upon any voluntary or involuntary liquidation,
          dissolution or winding up of the corporation;

               (5) the terms and conditions, if any, upon which shares of such
          series shall be convertible into, or exchangeable for, shares of stock
          of any other class or exchangeable for, shares of stock of any other
          class or classes, including the price or prices or the rate or rates
          of conversion or exchange and the terms of adjustment, if any;


               (6) The obligation, if any, of the corporation to retire or
          purchase shares of such series pursuant to a sinking fund or fund of a
          similar nature or otherwise, and the terms and conditions of such
          obligations;

               (7) Voting rights, if any, provided that the shares of all series
          with voting rights shall not have more than one vote per share;

               (8) limitations, if any, on the issuance of additional shares of
          such series or any shares of any other series of Preferred Stock; and

               (9) Such other preferences or restrictions or qualifications
          thereof as the Board of Directors may deem advisable and are not
          inconsistent with law and the provisions of these Articles.

               C. Statement of Limitations, Relative Rights and Powers in
          Respect of Shares of Common Stock.

               (1) After the requirements with respect to preferential dividends
          on the Preferred Stock (fixed in accordance with the provisions of
          paragraph 5 above) shall have been met and after the


                                         -4-

          corporation shall have complied with all the requirements, if any,
          with respect to the setting aside of sums as sinking funds or
          redemption or purchase accounts (fixed in accordance with the
          provisions of said paragraph B), then and not otherwise the holders of
          Common Stock shall be entitled to receive such dividends as may be
          declared from time to time by the Board of Directors.

               (2) After distribution in full of the preferential amount (fixed
          in accordance with the provisions of said paragraph B) to be
          distributed to the holders of Preferred Stock in the event of
          voluntary or involuntary liquidation, distribution or sale of assets,
          dissolution or winding up of this corporation, the holders of the
          Common Stock shall be entitled to receive all the remaining assets of
          this corporation, tangible and intangible, of whatever kind available
          for distribution to the stockholders ratably in proportion to the
          number of shares of Common Stock held by them respectively.


               (3) Except as may otherwise be required by law or the provisions
          of these Articles, or by the Board of Directors pursuant to authority
          granted in these Articles, each holder of Common Stock shall have one
          vote in respect of each share of stock held by him in all matters
          voted upon by the stockholders.

              D.   Denial of Preemptive rights.

               No holder of shares of the Common Stock or of the Preferred Stock
          shall be entitled as such, as a matter of right, to subscribe for or
          purchase any part of any new or additional issue of stock of any class
          whatsoever of the corporation, or of securities convertible into stock
          of any class, whether now or hereafter authorized, or whether issued
          for cash or other consideration or by way of dividend."

               The foregoing amendment will become effective when these articles
          of amendment are filed in accordance with the vote adopting the
          amendment, a later effective date not more than thirty days after such

                              ANALOG DEVICES, INC.

                           Votes of Board of Directors
                  Creating Series A Convertible Preferred Stock


VOTED:    That pursuant to authority expressly vested in the Board of Directors
          of the Corporation by Article 4 of the Articles of Organization of the
          Corporation, as amended, the Board of Directors hereby authorizes the
          issuance of a series of Preferred Stock, $1.00 par value per share, of
          the Corporation, consisting of 10,000 shares and designated as "Series
          A Convertible Preferred Stock" of the Corporation; and

FURTHER
VOTED:    That the relative rights, preferences, powers, qualifications,
          limitations and restrictions of the Series A Convertible Preferred
          Stock (hereinafter referred to as the "Series A Stock") authorized to
          be issued pursuant to the foregoing vote shall be as follows:

          1.   Dividends. In each fiscal year of the Corporation holders of 
          shares of Series A Stock shall be entitled to receive, before any cash
          dividends shall be declared and paid upon or set aside for the Common
          stock in such fiscal year, when and as declared by the Board of
          Directors of the Corporation, out of funds legally available for that
          purpose, dividends payable in cash in an amount per share for such
          fiscal year at least equal to the per share amount, if any, of any
          cash dividend for the Common Stock during such fiscal year. All
          dividends declared upon Series A Stock shall be declared pro rata per
          share.

          2.   Liquidation, Dissolution or Winding Up. In the event of any 
          liquidation, dissolution or winding up of the Corporation, the holders
          of shares of Series A Stock then outstanding shall, unless they elect
          to convert their Series A Stock into Common Stock as set forth in
          Section 4(d) hereof, be entitled to be paid out of the assets of the
          Corporation available for distribution to its stockholders, whether
          from capital, surplus or earnings, before any payment shall be made to
          the holders of any stock ranking on liquidation junior to the Series A
          Stock (with respect to rights on liquidation, dissolution or winding
          up, the Series A

                                       -2-

<PAGE>   42

          Stock shall rank prior to the Common Stock) an amount equal to One
          Thousand Dollars ($1,000) per share. If upon any liquidation,
          dissolution or winding up of the Corporation the assets of the
          Corporation available for the distribution to its stockholders shall
          be insufficient to pay the holders of shares of Series A Stock the
          full amounts to which they respectively shall be entitled, the holders
          of shares of Series A Stock and any class of stock ranking on
          liquidation on a parity with the Series A Stock shall share ratably in
          any distribution of assets according to the respective amounts which
          would be payable in respect of the shares held by them upon such
          distribution if all amounts payable on or with respect to said shares
          were paid in full. The merger or consolidation of the Corporation into
          or with another corporation, the merger or consolidation of any other
          corporation into or with the Corporation, or the sale, transfer,
          mortgage, pledge or lease of all or substantially all the assets of
          the Corporation shall not be deemed to be a liquidation, dissolution
          or winding up of the Corporation.

          3.   Voting. The shares of Series A Stock shall have no voting rights 
          or power and the holders of such shares shall not be entitled to vote
          such shares upon or in respect of any matter submitted to stockholders
          for vote or action, except (a) as otherwise required by law and (b)
          that the affirmative vote or consent of the holders of sixty-six and
          two-thirds percent (66-2/3%) of the shares of outstanding Series A
          Stock shall be required to authorize any issuance of Common Stock or
          securities convertible into shares of Common Stock by the Corporation
          in a transaction or series of related transactions designed to
          increase the Corporation's equity ownership in an entity (or the
          assets of an entity) in which the Corporation's initial investment was
          funded with the proceeds of the sale of shares of Series A Stock and
          such issuance increases the number of outstanding shares of Common
          Stock on a fully converted basis (treating as outstanding for this
          purpose all common stock equivalents determined in accordance with
          generally accepted accounting principles) by two percent (2%) or more.
          If any matter is to be submitted to the vote or consent of the holders
          of Series A Stock pursuant to the provisions of this Section 3, the
          Corporation shall provide such holders with not less than ten (10)
          days' prior written notice thereof and each share of Series A Stock
          shall be entitled to one vote (in person or by proxy) with respect to
          such


                                       -3-

<PAGE>   43


          matter, voting in the manner provided for in the By-laws of the
          Corporation.

          4.   Conversion.

               (a) Shares of Series A Stock may be converted, at the
          option of the holder thereof, in the manner hereinafter provided, into
          fully paid and non-assessable shares of Common Stock of the
          Corporation, at any time during the one-year period (the "Conversion
          Period") commencing (i) on the day ("Conversion Date") which is five
          (5) years from the date of issue of such shares of Series A Stock by
          the Corporation ("Issue Date") and ending (ii) on the day ("Expiration
          Date") which is six (6) years from the Issue Date of such shares of
          Series A Stock. If any holder of such shares does not elect to convert
          such shares at any time during the Conversion Period, such shares
          shall automatically, without any action on the part of the holder
          thereof, be converted into shares of Common Stock of the Corporation
          on the Expiration Date for such shares of Series A Stock. The Series A
          Stock shall be converted into Common Stock of the Corporation during
          the Conversion Period, whether such conversion is voluntary or
          involuntary, by the Corporation's issuance of that number of shares of
          Common Stock determined by multiplying the number of shares of Series
          A Stock then being converted by a fraction of which the numerator
          shall be $2,000 and the denominator shall be the greater of (x) the
          fair market value per share of Common Stock on the Conversion Date or
          (y) one and one-half (1-1/2) times the book value per share of Common
          Stock, as such book value per share is shown on the balance sheet of
          the Corporation as of the end of the fiscal quarter immediately
          preceding the Conversion Date. For the purpose hereof, "fair market
          value per share" shall mean the average closing price per share of the
          Common stock of the Corporation on the New York Stock Exchange
          Composite Tape for the sixty (60) day period ending ten (10) days
          prior to the Conversion Date; provided, however, that if the Common
          Stock of the Corporation is not then listed on the New York Stock
          Exchange such fair market value shall be the average of the mean
          between the closing bid and asked prices of the Common Stock of the
          Corporation for such 60-day period in the over-the-counter market or,
          if such shares are not then traded in the over-the-counter market or
          any other national securities exchange, such fair market value shall
          be determined by the Board of Directors of the Corporation.


                                       -4-

<PAGE>   44


               (b) In case of any consolidation of the corporation with, or 
          merger of the Corporation into, another corporation (other than a
          consolidation or merger in which the Corporation is the continuing
          corporation) or in case of any sale or conveyance to another
          corporation of the assets of the Corporation as an entirety or
          substantially as an entirety, which shall occur while any shares of
          Series A Stock are outstanding, each share of Series A Stock shall
          automatically, without any action on the part of the holder thereof,
          be converted into Common Stock, immediately prior to or
          contemporaneously with such consolidation, merger, sale or conveyance,
          and the holders of Series A Stock shall thereafter be entitled to
          receive, together with all other holders of Common Stock, the kind and
          amount of shares of stock and other securities and property receivable
          upon such consolidation, merger, sale or conveyance by the holders of
          Common Stock. The conversion of Series A Stock for purposes of this
          paragraph (b) shall be effected by the Corporation's issuance of that
          number of shares of Common Stock determined by multiplying the number
          of shares of Series A Stock then being converted by a fraction of
          which the numerator shall be the sum of $1,000 plus the product of (x)
          $16.66 2/3 multiplied by (y) the number of months (but not in excess
          of sixty (60) months in the aggregate) which elapse during the period
          commencing with the Issue Date and ending as of the end of the month
          immediately preceding the date of such consolidation, merger, sale or
          conveyance, and the denominator shall be the average closing price per
          share of the Common Stock of the Corporation on the New York Stock
          Exchange Composite Tape for the sixty (60) day period ending thirty
          (30) days prior to the date that the Corporation shall have first
          publicly announced the proposed consolidation, merger, sale or
          conveyance; provided, however, that if the Common Stock of the
          Corporation is not then listed on the New York Stock Exchange, such
          per share price shall be determined, on the basis of such 60-day
          period, as set forth in Section 4(a) hereof.

               (c) In case any person shall make a tender offer to purchase at 
          least fifty-one percent (51%) of the then outstanding shares of Common
          Stock of the Corporation ("Tender Offer") at any time while Series A
          Stock is outstanding, each holder of shares of Series A Stock shall
          have the right, at his election, to convert such shares into Common
          Stock of the Corporation during the period commencing with the first
          public announcement of

                                       -5-

<PAGE>   45


          the Tender Offer ("Offer Date") and ending on the date of expiration
          of the Tender Offer. If any holder elects to so convert his Series A
          Stock pursuant to this paragraph (c), the conversion shall be effected
          by the Corporation's issuance of that number of shares of Common Stock
          determined by multiplying the number of shares of Series A Stock then
          being converted by a fraction of which the numerator shall be the sum
          of $1,000 plus the product of (x) $16.66 2/3 multiplied by (y) the
          number of months (but not in excess of sixty (60) months in the
          aggregate) which elapse during the period commencing with the Issue
          Date and ending as of the end of the month immediately preceding the
          Offer Date, and the denominator shall be the average closing price per
          share of the Common Stock of the Corporation on the new York Stock
          Exchange Composite Tape for the sixty (60) day period ending thirty
          (30) days prior to the Offer Date; provided, however, that if the
          Common Stock of the Corporation is not then listed on the New York
          Stock Exchange, such per share price shall be determined, on the basis
          of such 60-day period, as set forth in Section 4(a) hereof.

               (d) In case of any liquidation, dissolution or winding up of the 
          Corporation ("liquidation"), whether voluntary or involuntary, in lieu
          of the right to receive the payments specified in Section 2 hereof,
          the holders of shares of Series A Stock then outstanding shall have
          the right to convert the Series A Stock into Common Stock, up to and
          until the close of business on the full business day next preceding
          the date fixed for the liquidation of the Corporation, the conversion
          thereof to be effected by the Corporation's issuance of that number of
          shares of Common Stock of the Corporation determined by multiplying
          the number of shares of Series A Stock then being converted by a
          fraction of which the numerator shall be the sum of $1,000 plus the
          product of (x) $16.66 2/3 multiplied by (y) the number of months (but
          not in excess of 60 months in the aggregate) which elapse during the
          period commencing with the Issue Date and ending as of the end of the
          month immediately preceding the date of such liquidation, and the
          denominator shall be the amount (or value if other than cash) per
          share of Common Stock to be distributed to the holders of Common Stock
          in liquidation of the Corporation.

               (e)  The Corporation shall not issue fractions of shares of 
          Common Stock upon conversion of Series A Stock or scrip in lieu
          thereof. If any fraction of a share of

                                       -6-

<PAGE>   46


          Common Stock would, except for the provisions of this paragraph (e),
          be issuable upon conversion of Series A Stock, the Corporation shall
          in lieu thereof pay to the person entitled thereto an amount in cash
          equal to the current value of such fraction, calculated to the nearest
          one-thousandth (1/1000) of a share, to be computed (i) if the Common
          Stock is listed on any national securities exchange on the basis of
          the last sales price of the Common Stock on such exchange (or the
          quoted closing bid price if there shall have been no sales) on the
          Conversion Date (or Merger Date, Offer Date or date of liquidation, as
          the case may be), or (ii) if the Common Stock shall not be so listed,
          on the basis of the mean between the closing bid and asked prices for
          the Common Stock on the Conversion Date (or Merger Date, Offer Date or
          date of liquidation, as the case may be) as reported by NASDAQ, or its
          successor, and if there are no such closing bid and asked prices, on
          the basis of the fair market value per share as determined by the
          Board of Directors of the Corporation.

               (f) In order to exercise the conversion privilege, the holder of 
          any Series A Stock to be converted shall surrender his or its
          certificate or certificates therefor to the principal office of the
          transfer agent for the Series A Stock (or if no transfer agent be at
          the time appointed, then to the Corporation at its principal office),
          and shall give written notice to the Corporation at such office that
          the holder elects to convert the Series A Stock represented by such
          certificates. Such notice shall also state the name or names (with
          address) in which the certificate or certificates for shares of Common
          Stock which shall be issuable on such conversion shall be issued. As
          soon as practicable after receipt of such notice and the surrender of
          the certificate or certificates for Series A Stock as aforesaid, the
          Corporation shall cause to be issued and delivered at such office to
          such holder, or on his or its written order, a certificate or
          certificates for the number of full shares of Common Stock issuable on
          such conversion in accordance with the provisions hereof and cash as
          provided in paragraph (e) hereof in respect of any fraction of a share
          of Common Stock otherwise issuable upon such conversion.

               (g) On the date that any conversion takes effect hereunder, all 
          shares of Series A Stock then to be converted shall cease to have any
          rights with respect to such stock, and the sole rights of the holders
          of such stock shall be with respect to the Common Stock into

                                       -7-

<PAGE>   47


          which such shares have been so converted. Each holder of an
          outstanding certificate of Series A Stock which, prior to conversion
          represented shares of Series A Stock, shall be entitled to receive
          therefor, on and after the date that any such conversion takes effect,
          a certificate or certificates representing the number of shares of
          Common Stock into which such shares shall have been converted, upon
          surrender of such certificate or certificates to such agent or agents
          as may be appointed by the Corporation. If so required by the
          Corporation, certificates surrendered for conversion shall be endorsed
          or accompanied by a written instrument or instruments of transfer in
          form satisfactory to the Corporation, duly executed by the registered
          holder or by his attorney duly authorized in writing. All certificates
          evidencing shares of Series A Stock which are required to be
          surrendered for conversion in accordance with the provisions hereof
          shall, from and after the date such certificates are so required to be
          surrendered, be deemed to have been retired and cancelled and the
          shares of Series A Stock represented thereby converted into Common
          Stock for all purposes, notwithstanding the failure of the owner or
          owners thereof to surrender such certificates on or prior to said
          date.

               (h)  In case:

                    (i) of any consolidation or merger to which the Corporation 
          is a party and for which approval of any stockholders of the
          Corporation is required, or of the sale or transfer of all or
          substantially all of the assets of the Corporation; or

                    (ii) of the involuntary or voluntary dissolution, 
          liquidation or winding up of the Corporation;

          then the Corporation shall cause to be filed at the office of the
          transfer agent of the Series A Stock and shall cause to be mailed to
          the holders of the Series A Stock, at their last addresses as they
          shall appear upon the record of such transfer agent at least twenty
          (20) days before the date specified herein below, a notice stating the
          date on which such consolidation, merger, sale, transfer, dissolution,
          liquidation or winding up is expected to become effective, and the
          date as of which it is expected that holders of Common Stock of record
          shall be entitled to exchange their shares of Common Stock for
          securities or other property

                                       -8-

<PAGE>   48


          deliverable upon such consolidation, merger, sale, transfer,
          dissolution, liquidation or winding up.

               (i) The Corporation shall use its best efforts, at all times 
          when the Series A Stock shall be outstanding, to reserve and keep
          available out of its authorized but unissued stock, for the purpose of
          effecting the conversion of the Series A Stock, such number of its
          duly authorized shares of Common Stock as shall from time to time be
          sufficient to effect the conversion of all outstanding Series A Stock.
          Before taking any action which would cause an adjustment reducing the
          conversion price below the then par value of the shares of Common
          Stock issuable upon conversion of the Series A Stock, the Corporation
          will take any corporate action which may, in the opinion of its
          counsel, be necessary in order that the Corporation may validly and
          legally issue fully paid and non-assessable shares of such Common
          Stock at such adjusted conversion price.

               (j) Upon any such conversion, no adjustment shall be made for 
          accrued and unpaid dividends on the Series A Stock surrendered for
          conversion or on the Common Stock delivered.

               (k) All shares of Series A Stock which shall have been 
          surrendered for conversion as herein provided shall no longer be
          deemed to be outstanding and all rights with respect to such shares,
          including the rights, if any, to receive notices and to vote, shall
          forthwith cease and terminate except only the right of the holders
          thereof to receive Common Stock in exchange therefor. Any shares of
          Series A Stock so converted shall be retired and cancelled and shall
          not be reissued, and the Corporation may from time to time take such
          appropriate action as may be necessary to reduce the authorized Series
          Stock accordingly.

          5.   Definitions. The term "Common Stock" shall be deemed to refer 
          to the Common Stock, $.16 2/3 par value per share, authorized by the
          Articles of Organization of the Corporation, as amended and in effect
          on the date hereof, and to any additional share of stock of any class
          of the Corporation other than preferred stock with a fixed limit on
          dividends and a fixed amount payable in the event of any voluntary or
          involuntary liquidation, dissolution or winding up of the Corporation.

FURTHER
VOTED:    That Article 6 of the Articles of Organization of the Corporation 
shall be amended by deleting in its entirety the current Article 6A, and by
substituting new Article 6A therefor, to read as follows:

6A.  INDEMNIFICATION

     Section 1. Actions, Suits and Proceedings. Except as otherwise provided
below, the Corporation shall, to the fullest extent authorized by Chapter 156B
of the Massachusetts General Laws, as the same exists or may hereafter be
amended (in the case of any such amendment, only to the extent that such
amendment either (i) permits the Corporation to provide broader indemnification
rights than such laws permitted prior to such amendment or (ii) prohibits or
limits any of the indemnification rights previously set forth in such laws),
indemnify each person who is, or shall have been, a director or officer of the
Corporation or who is or was a director or employee of the Corporation and is
serving, or shall have served, at the request of the Corporation, as a director
or officer of another organization or in any capacity with respect to any
employee benefit plan of the Corporation, against all liabilities and expenses
(including judgments, fines, penalties, amounts paid or to be paid in
settlement, and reasonable attorneys' fees) imposed upon or incurred by any such
person (the "Indemnitee") in connection with, or arising out of, the defense or
disposition of any action, suit or other proceeding, whether civil or criminal,
in which he may be a defendant or with which he may be threatened


                                       -3-

<PAGE>   75


or otherwise involved, directly or indirectly, by reason of his being or having
been such a director or officer or as a result of his serving or having served
with respect to any such employee benefit plan; provided, however, that the
Corporation shall provide no indemnification with respect to any matter as to
which any such Indemnitee shall be finally adjudicated in such action, suit or
proceeding not to have acted in good faith in the reasonable belief that his
action was (i) in the best interests of the Corporation or (ii) to the extent
such matter relates to service with respect to an employee benefit plan, in the
best interests of the participants or beneficiaries of such employee benefit
plan.

     Section 2. Settlements. The right to indemnification conferred in this
Article shall include the right to be paid by the Corporation for liabilities
and expenses incurred in connection with the settlement or compromise of any
such action, suit or proceeding, pursuant to a consent decree or otherwise,
unless a determination is made, within 45 days after receipt by the Corporation
of a written request by the Indemnitee for indemnification, that such settlement
or compromise is not in the best interests of the Corporation or, to the extent
such matter relates to service with respect to an employee benefit plan, that
such settlement or compromise is not in the best interests of the participants
or beneficiaries of such plan. Any such determination shall be made (i) by the
Board of Directors of the corporation by a majority vote of a quorum consisting
of disinterested directors, or (ii) if such quorum is not obtainable, by a
majority of the disinterested directors of the Corporation then in office.
Notwithstanding the foregoing, if there are less than two disinterested
directors then in office, the Board of Directors shall promptly direct that
independent legal counsel (who may be regular legal counsel to the Corporation)
determine, based on facts known to such counsel at such time, whether such
Indemnitee acted in good faith in the reasonable belief that his action was in
the best interests of the Corporation or the participants or beneficiaries of
any such employee benefit plan, as the case may be; and, in such event,
indemnification shall be made to such Indemnitee unless, within 45 days after
receipt by the Corporation of the request by such Indemnitee for
indemnification, such independent legal counsel in a written opinion to the
Corporation determines that such Indemnitee did not act in good faith in the
reasonable belief that his action was in the best interests of the Corporation
or the participants or beneficiaries of any such employee benefit plan, as the
case may be.

     Section 3. Notification and Defense of Claim. As a condition precedent to
his right to be indemnified, the Indemnitee must give to the Corporation notice
in writing as soon as



                                       -4-

<PAGE>   76


practicable of any action, suit or proceeding involving him for which indemnity
will or could be sought. With respect to any action, suit or proceeding of which
the Corporation is so notified, the Corporation will be entitled to participate
therein at its own expense and/or to assume the defense thereof at its own
expense, with legal counsel reasonably acceptable to such Indemnitee. After
notice from the Corporation to the Indemnitee of its election so to assume such
defense, the Corporation shall not be liable to such Indemnitee for any legal or
other expenses subsequently incurred by such Indemnitee in connection with such
claim, but the fees and expenses of such counsel incurred after notice from the
Corporation of its assumption of the defense thereof shall be at the expense of
the Indemnitee unless (i) the employment of counsel by the Indemnitee has been
authorized by the Corporation, (ii) counsel to the Indemnitee shall have
reasonably concluded that there may be a conflict of interest or position on any
significant issue between the Corporation and the Indemnitee in the conduct of
the defense of such action or (iii) the Corporation shall not in fact have
employed counsel to assume the defense of such action, in each of which cases,
the fees and expenses of counsel for the Indemnitee shall be at the expense of
the Corporation, except as otherwise expressly provided by this Article. The
Corporation shall not be entitled to assume the defense of any claim brought by
or on behalf of the Corporation or as to which counsel for the Indemnitee shall
have reasonably made the conclusion provided for in (ii) above.

     Section 4. Advance of Expenses. Subject to Section 3 above, the right to
indemnification conferred in this Article shall include the right to be paid by
the Corporation for expenses (including reasonable attorneys' fees) incurred in
defending a civil or criminal action, suit or proceeding in advance of its final
disposition, subject to receipt of an undertaking by the Indemnitee to repay
such payment if it is ultimately determined that the Indemnitee is not entitled
to indemnification under this Article. Such undertaking may be accepted without
reference to the financial ability of such Indemnitee to make such repayment.
Notwithstanding the foregoing, no advance shall be made by the Corporation under
this Section 4 if a determination is reasonably and promptly made by the Board
of Directors by a majority vote of a quorum consisting of disinterested
directors or, if such quorum is not obtainable, by a majority of the
disinterested directors of the Corporation then in office or, if there are not
at least two disinterested directors then in office, by independent legal
counsel (who may be regular legal counsel to the Corporation) in a written
opinion that, based on facts known to the Board or counsel at such time, such
Indemnitee did not act in good faith in the reasonable belief that his action
was in the best interests of the Corporation or the participants or
beneficiaries of an employee benefit plan of the Corporation, as the case may
be.

<PAGE>   77



     Section 5. Partial Indemnity. If an Indemnitee is entitled under any
provision of this Article to indemnification by the Corporation for some or a
portion of the liabilities or expenses imposed upon or incurred by such
indemnitee in the investigation, defense, appeal or settlement of any action,
suit or proceeding but not, however, for the total amount thereof, the
Corporation shall nevertheless indemnify the Indemnitee for the portion of such
iabilities or expenses to which such Indemnitee is entitled.

     Section 6. Rights Not Exclusive. The right to indemnification and the
payment of expenses incurred in defending any action, suit or proceeding in
advance of its final disposition conferred in this Article shall not be
exclusive of any other right which any person may have or hereafter acquire
under any statute, provision of the Articles of Organization, By-Laws,
agreement, vote of stockholders or directors or otherwise. Without limiting the
generality of the foregoing, the Corporation, acting through its Board of
Directors, may enter into agreements with any director, officer, employee or
agent of the Corporation providing for indemnification rights equivalent to or
greater than the indemnification rights set forth in this Article.

     Section 7. Insurance. The Corporation may purchase and maintain insurance,
at its expense, to protect itself and any director, officer, employee or agent
of the Corporation or another organization or employee benefit plan against any
expense or liability incurred by him in any such capacity, or arising out of the
status as such, whether or not the Corporation would have the power to indemnify
such person against such expense or liability under Chapter 156B of the
Massachusetts General Laws.

     Section 8. Insurance Offset. The Corporation's obligation to provide
indemnification under this Article shall be offset to the extent of any other
source of indemnification or any otherwise applicable insurance coverage under a
policy maintained by the Corporation or any other person.

     Section 9. Amendment. Without the consent of a person entitled to the
indemnification and other rights provided in this rticle (unless otherwise
required by Chapter 156B of the Massachusetts General Laws), no amendment
modifying or terminating such rights shall adversely affect such person's rights
under this Article with respect to the period prior to such Amendment.

     Section 10. Mergers, Etc. If the Corporation is merged into or consolidated
with another corporation and the Corporation is not the surviving corporation,
or if substantially all of the assets of the Corporation are acquired by any
other corporation, or in the event of any other similar reorganization involving
the



                                       -6-

<PAGE>   78


Corporation, the Board of Directors of the Corporation or the board of directors
of any corporation assuming the obligations of the Corporation shall assume the
obligations of the Corporation under this Article, through the date of such
merger, consolidation, sale or reorganization, with respect to each person who
is entitled to indemnification rights under this Article as of such date.

     Section 11. Savings Clause. If this Article or any portion hereof shall be
invalidated on any ground by any court of competent jurisdiction, then the
Corporation shall nevertheless indemnify each Indemnitee as to any liabilities
and expenses with respect to any action, suit or proceeding to the full extent
permitted by any applicable portion of this Article that shall not have been
invalidated and to the full extent permitted by applicable law.

     Section 12. Definitions. As used in this Article, the term "director",
"officer" and "person" include their respective heirs, executors,
administrators, and legal representatives, and an "interested" director is one
against whom in such capacity the proceedings in question or another proceeding
on the same or similar grounds is then pending.

FURTHER
VOTED:    That Article 6 of the Articles of Organization of the Corporation 
shall be amended by adding new Article 6D, to read as follows:

     6D.  LIMITATION OF DIRECTOR LIABILITY

     To the fullest extent permitted by Chapter 156B of the Massachusetts
General Laws, as it may be amended from time to time, a director of the
Corporation shall not be personally liable to the Corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director,
notwithstanding any provision of law imposing such liability.

     The foregoing amendment will become effective when these articles of
Amendment are filed in accordance with Chapter 156B, Section 6 of The General
Laws unless these articles specify, in accordance with the vote adopting the
amendment, a later effective date not more than thirty days after such filing,
in which event the amendment will become effective on such later date.

Ladies and Gentlemen:

     We have assisted in the preparation of a Registration Statement on Form S-8
(the "Registration Statement") to be filed with the Securities and Exchange
Commission relating to 6,900,000 shares of Common Stock, $.16 2/3 par value per
share (the "Shares"), of Analog Devices, Inc., a Massachusetts corporation (the
"Company"), issuable under the Company's Amended 1988 Stock Option Plan (as
amended, the "Plan").

     We have examined the Restated Articles of Organization and the By-Laws of
the Company, and all amendments thereto, the Registration Statement and
originals, or copies certified to our satisfaction of such records of meetings
of the directors and stockholders of the Company, and such other documents and
instruments as in our judgment are necessary or appropriate to enable us to
render the opinions expressed below.

     In our examination of the foregoing documents, we have assumed the
genuineness of all signatures and the authenticity of all documents submitted to
us as originals, the conformity to original documents of all documents submitted
to us as certified or photostatic copies, and the authenticity of the originals
of such latter documents.

     Based upon and subject to the foregoing, we are of the opinion that the
Shares covered by the Registration Statement to be issued under the Plan have
been duly and validly authorized for issuance, and when issued and paid for in
accordance with the terms of the Plan, will be legally issued, fully paid and
nonassessable.

     We hereby consent to the filing of this opinion with the Securities and
Exchange Commission as an exhibit to the Registration Statement.

                                       Very truly yours,

                                       HALE AND DORR
