Exhibit 99

Analog Devices Provides Preliminary Results for Third Quarter of Fiscal 2005

    NORWOOD, Mass.--(BUSINESS WIRE)--Aug. 2, 2005--Analog Devices
(NYSE:ADI) today estimated, on a preliminary basis, its revenue for
the fiscal third quarter ended July 30, 2005 will be in the range of
$580 to $585 million, down approximately 3% to 4% from the immediately
prior quarter. This revised revenue estimate is below the guidance of
0% to 3% growth communicated on May 12, 2005, due primarily to an
estimated $23 million sequential decline from the second quarter in
sales of GSM/GPRS base band chipsets to wireless handset customers in
Asia. Wireless handsets represented approximately 10% of revenue in
the third quarter.

    According to Mr. Jerald Fishman, President and CEO, "Although the
communications market was generally weak, the revised outlook is
primarily related to lower sales of GSM/GPRS chipsets to Asian
customers who continue to struggle against increased global
competition. As these customers begin to supply more feature-rich
phones this fall, we believe that our wireless handset revenue will
begin to recover.

    "Most other application areas performed largely according to our
third quarter plan. The industrial end markets grew sequentially with
strength in broad-based industrial products offset by declines in
automatic test equipment (ATE) and automotive. Revenue from computer
and consumer customers also grew in the third quarter compared to the
immediately prior quarter.

    "In line with normal seasonal patterns, our analog product revenue
was approximately flat in the third quarter compared to the
immediately prior quarter, after growing over 6% sequentially in the
second quarter compared to the first quarter of fiscal 2005."

    Third quarter gross margins are estimated to be approximately 58%.
Operating expenses are estimated to decline approximately 3% compared
to the immediately prior quarter, resulting in an estimated operating
profit margin of approximately 22.5%. Based on these estimates,
earnings per share (EPS) under generally accepted accounting
principles are estimated to be approximately $0.31 for the third
quarter, at the low end of the range communicated in May.

    Inventory is expected to decline on a dollar basis in the third
quarter compared to the second quarter. Cash flow from operations is
estimated to continue to be strong during the third quarter.

    Commenting on recent demand trends, Mr. Fishman said, "Order rates
increased in the third quarter, above second quarter levels, and were
very strong in July. As a result, we began the fourth quarter with
higher backlog than at the start of the third quarter. We continue to
believe that overall, we are in a gradual recovery that began six
months ago."

    Estimated results for the third quarter presented in this release
are subject to change based on the finalization of the third quarter
results. The final results for the third quarter will be released at
the regularly scheduled time of 4:00 pm Eastern time on Thursday,
August 11, 2005.
