                                EXPLANATORY NOTE

This Quarterly  Report on Form 10-Q/A  (Amendment No. 1) amends Item 1 of Part I
of the  Quarterly  Report on Form 10-Q filed by the Company on May 15, 2001.  To
the extent this  amended  filing is  inconsistent  with the  Company's  original
Quarterly  Report on Form 10-Q for the quarterly period ended April 1, 2001, the
original  filing  is hereby  superseded  and  amended.  To the  extent  that the
original  filing is unaffected by this  amendment,  the original  filing has not
been updated to reflect events  subsequent to the periods covered or the date of
the original filing.

On April 17, 2001, after the end of the third quarter,  the Company announced it
would  increase its  quarterly  dividend per share from $0.03 per share to $0.04
per share for  stockholders  of record on April 27, 2001.  In its original  Form
10-Q the Company  reported  its  dividend at $0.04 per share for the quarter and
$0.10 per share for the nine  months of fiscal  2001  rather  than the $0.03 and
$0.09, respectively, actually paid during the quarter.

                          LINEAR TECHNOLOGY CORPORATION
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)

1.   Interim financial statements and information are unaudited; however, in the
     opinion of  management  all  adjustments  necessary for a fair and accurate
     presentation  of the interim  results have been made. All such  adjustments
     were of a normal  recurring  nature.  The results for the three  months and
     nine  months  ended  April 1, 2001 are not  necessarily  an  indication  of
     results to be expected for the entire fiscal year. All information reported
     in this Form 10-Q/A should be read in conjunction with the Company's annual
     consolidated  financial  statements  for the fiscal year ended July 2, 2000
     included in the Company's Annual Report to  Shareholders.  The accompanying
     balance  sheet at July 2,  2000 has been  derived  from  audited  financial
     statements  as of that date.  There were no  material  differences  between
     comprehensive income and net income for all periods presented.  Because the
     Company is viewed as a single operating segment for management purposes, no
     segment information has been disclosed.

2.   The Company operates on a 52/53 week year ending on the Sunday nearest June
     30.  Fiscal 2001 will consist of 52 weeks,  compared to 53 weeks for fiscal
     2000.

3.   Basic earnings per share is calculated using the weighted average shares of
     common stock outstanding  during the period.  Diluted earnings per share is
     calculated using the weighted  average shares of common stock  outstanding,
     plus the dilutive  effect of stock  options  calculated  using the treasury
     stock method. The following table sets forth the reconciliation of weighted
     average  common shares  outstanding  used in the  computation  of basic and
     diluted earnings per share:

         Net  sales for the  quarter  ended  April 1, 2001 were a record  $282.0
million, an increase of $96.9 million or 52% over net sales for the same quarter
of the previous year. Although the average selling price increased slightly, the
principal cause for this increase was higher unit shipments.  Sales increased in
all major geographic areas, with the USA and international  remaining their same
percentage  of sales at 45% and 55%  respectively  as in the prior year.  Within
international,  Europe was 25% of sales, Japan 14%, and other geographical areas
primarily  the rest of Asia 16%.  Relative  to  end-market  applications,  sales
increased  significantly  over the prior year's quarter in each of the Company's
three major end  markets,  with the most  growth  occurring  in  communications,
followed by industrial and computer.

         Net sales for the nine  months  ended  April 1, 2001  increased  $277.7
million or 56% over net sales for the same  period of the  previous  year.  This
increase  was due to higher unit  shipments,  as the average  selling  price was
largely unchanged.  Sales increased in all geographic areas and in all major end
markets, led by communications.

         Gross profit  increased  $79.2 million or 58% and $222.8 million or 61%
for the third quarter and first nine months of fiscal 2001,  respectively,  over
the  corresponding  periods in fiscal 2000. The improvement in gross profit as a
percentage of net sales was due to the favorable effect of fixed costs allocated
across a higher sales base and improved  manufacturing  efficiencies  and yields
achieved at the Company's fabrication,  assembly and test facilities,  partially
offset by costs associated with the start-up of the new wafer  fabrication plant
in Milpitas.

         Research and development  ("R&D") expenses increased by $9.1 million or
47% and $22.7  million or 40% for the third  quarter  and first  nine  months of
fiscal 2001,  respectively,  as compared to the same periods in fiscal 2000. The
increases  in R&D  expenses  compared  to the  prior  year  periods  were due to
increases in staffing levels of design engineering personnel,  which resulted in
higher  compensation  costs;  increased  profit  sharing  costs  driven  by  the
increases  in sales and  profitability;  and  development  costs in new  product
areas.

                                       9


         Selling, general and administrative expenses ("SG&A") increased by $6.1
million  or 31% and $17.3  million or 33% for the third  quarter  and first nine
months of fiscal 2001,  respectively,  as compared to the same periods in fiscal
2000. The increases in SG&A expenses compared to the prior year periods were due
primarily  to an  increase in staffing  levels to support  the  increased  sales
volume;  higher profit sharing costs and higher  commissions  resulting from the
increase in sales;  and higher  legal  costs  related to patent  protection  and
infringement.

         Interest  income  was $16.7  million  and $47.8  million  for the third
quarter and first nine months of fiscal  2001,  an increase of $5.6  million and
$17.8 million, respectively,  over the corresponding periods of fiscal 2000. The
increase in interest income resulted from an increase in the cash and investment
balances  and a slightly  higher  average  interest  rate versus the  comparable
periods of the prior fiscal year.

         The  Company's  effective  tax rate for the third quarter and the first
nine months of fiscal 2001 was 30.0%,  down from 31.0% in fiscal 2000. The lower
tax  rate  is  due   primarily  to  increased   business   activity  in  foreign
jurisdictions  with lower tax rates, an increase in tax-exempt  interest income,
the R&D credit and the Company's foreign sales corporation.

Factors Affecting Future Operating Results

         Except for historical  information  contained  herein,  the matters set
forth in this Form 10-Q/A, 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  and  financial  markets  and  other  factors
described below.

         In the short-term the Company, as with other  semiconductor  companies,
has seen a slowdown in net  bookings.  As the quarter  progressed  cancellations
continued to increase  and  bookings  decreased  both  significantly  across all
business areas, in all geographical areas and in all end-markets. North American
business activity was the weakest, particularly in the networking communications
area. While many customers are dealing with demand issues and excess  inventory,
the  Company  has  added  to its  capacity  having  put its new  Milpitas  wafer
fabrication plant into operation for the full quarter.  The convergence of these
three  events  has  caused  lead  times to drop  thereby  reducing  the need for
customers  to book orders at the  current  time.  The  Company is not  expecting
bookings to strengthen  significantly  soon, but as lead times remain low, turns
business,  business that is booked and shipped  within the same quarter,  should
increase  late in the  quarter.  The Company had been  growing at a 50%-60% rate
year over year for several  quarters and some correction is not surprising.  The
short-term  will be  difficult  as volume  curtails  and we believe next quarter
could be 20%-30% lower in sales than the quarter just ended. As in past economic
downturns the Company  estimates that its profitability as a percentage of sales
will not change  significantly  on the  forecasted  lower sales.  We continue to
believe this is more of a short-term  correction than a severe general  economic
problem as  design-in  activity at  customers  is very active and the demand for
high  performance  proprietary  analog  solutions in new generation end products
continues strong. The long-term prospects for the business are excellent and the
Company continues to invest in the plant  infrastructure and technical talent to
maximize its opportunities.

         Estimates of future performance are uncertain,  and 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,
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.  The Company's headquarters
and a portion of its  manufacturing  facilities and research and development and
certain other critical  business  operations  are located near major  earthquake
fault lines in California.  Consequently the Company could be adversely affected
in the  event  of a major  earthquake.  In  addition,  California  is  currently
experiencing the threat of interruption in the  availability of electricity.  To
date the impact on the Company has been  negligible.  However,  electricity is a
critical  resource  to the  Company  without  which  its  products  could not be
manufactured.  In the  three  and  nine  month  periods  ended  April  1,  2001,
electricity costs represented less than 1% of sales.

                                       10


         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. Furthermore, stocks of high technology
companies  are subject to extreme price and volume  fluctuations  that are often
unrelated or disproportionate to the operating performance of these companies.

Liquidity and Capital Resources

         At April 1, 2001,  cash, cash  equivalents  and short-term  investments
totaled $1,429.4 million, and working capital was $1,424.6 million.

         During the first nine  months of fiscal  2001,  the  Company  generated
$411.8  million of cash from  operating  activities.  Additionally,  the Company
generated  $38.9  million in proceeds  from common stock  issued under  employee
stock option and stock purchase plans.

         During  the  first  nine  months  of  fiscal  2001,   significant  cash
expenditures included net purchases of short-term  investments of $145.8 million
and $105.1 million for the purchase of capital assets,  primarily  manufacturing
equipment  for the  Company's  fabrication,  assembly and test  facilities.  The
Company also paid $63.3 million to repurchase  1.4 million  shares of its common
stock and $28.4 million for cash dividends to  stockholders  representing  $0.03
per share per quarter.  In April 2001, the Company's Board of Directors declared
an increase in the quarterly  cash dividend to $0.04 per share to be paid during
the June quarter of fiscal 2001.  The payment of future  dividends will be based
on quarterly financial performance.

         Historically,  the Company has satisfied  its  liquidity  needs through
cash generated from operations and the placement of equity securities. Given its
strong financial  condition and  performance,  the Company believes that current
capital  resources  and  cash  generated  from  operating   activities  will  be
sufficient to meet its liquidity and capital  expenditures  requirements for the
foreseeable future.
