Analog Devices Completes Sale of CPU Voltage and PC Thermal Monitoring
                     Business to ON Semiconductor

    NORWOOD, Mass.--(BUSINESS WIRE)--Jan. 2, 2008--Analog Devices,
Inc. (NYSE: ADI) today announced that it has completed the sale of its
CPU voltage regulation and PC thermal monitoring business to ON
Semiconductor Corporation (NASDAQ: ONNN), which was previously
announced in November 2007. The total cash consideration of
approximately $184 million paid to ADI includes the purchase price for
the acquired assets and intellectual property related to the product
lines as well as amounts paid under a one-year manufacturing supply
agreement with ON Semiconductor. ADI will record a one-time gain in
the first quarter of fiscal year 2008 related to this transaction. In
addition, beginning in the first quarter of fiscal year 2008 ADI will
account for the divested operations, including the operating results
related to the one-year manufacturing supply agreement, as
discontinued operations.

    The divestiture is consistent with ADI's ongoing transition of its
power management portfolio to high-performance products that
complement the company's market-leading portfolio of signal-processing
solutions for industrial, medical and scientific instrumentation, as
well as communications infrastructure and consumer electronics.
