Exhibit 99.1

 Analog Devices to Sell CPU Voltage and PC Thermal Monitoring
                   Product Line to ON Semiconductor

    NORWOOD, Mass.--(BUSINESS WIRE)--Nov. 8, 2007--Analog Devices,
Inc. (NYSE: ADI) today announced that it has signed a definitive
agreement to sell its CPU voltage regulation and PC thermal monitoring
product line to ON Semiconductor Corporation (NASDAQ: ONNN). The
product line to be sold consists of core voltage regulator products
for the central processing unit (CPU) in computing and gaming
applications and temperature sensors and fan-speed controllers for
managing the temperature of the CPU.

    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.

    "This agreement allows us to further focus our power management
team on areas such as portable medical devices, wireless
infrastructure equipment, and digital TVs, where ADI has outstanding
systems expertise and an unparalleled reputation for delivering high
performance signal processing solutions," said Peter Henry, ADI's vice
president for Power Management Products.

    "Power considerations play an important role with customers as
they look for ways to improve the sound, picture, and connectivity
features, as well as the battery life of their products. With a
complementary portfolio of power management products, ADI can help
customers innovate and achieve new levels of differentiation from
their signal processing subsystems," Mr. Henry continued.

    Pursuant to the agreement, Analog Devices will sell to ON certain
assets and intellectual property related to the product line and will
enter into a one-year manufacturing supply arrangement for a total
consideration of approximately $185 million in cash. The product line
represented approximately $80 million in revenue for ADI during fiscal
year 2007, which ended November 3, 2007.

    ADI management plans to discuss the transaction in more detail
during its fiscal 2007 fourth quarter earnings conference call
scheduled for Tuesday, November 27, at 4:30 p.m. ET.

    The boards of directors of both companies have approved the
transaction, which is expected to close during ADI's first quarter of
fiscal 2008, following the satisfaction of regulatory requirements and
other customary closing conditions.
