Industry's first CDC recognized for its high precision and cost
effectiveness in space-constrained and power-sensitive
applications. Analog Devices, Inc. (NYSE: ADI), a global leader in
high-performance semiconductors for signal-processing applications,
today announced that the AD7745, the industry's first
capacitance-to-digital converter (CDC) received Sensors Magazine's
"Best of Sensors Expo" award during its annual conference held last
week in Chicago. One of only three "gold" products cited for
excellence, the AD7745 received top honors in the category of
"sensor components." The CDC is a high-resolution sigma-delta
converter that accepts direct capacitance inputs and enables on a
single chip a level of precision previously only possible with
conventional analog voltage-to-digital converters. This eliminates
the discrete components needed for traditional multi-chip solutions
and makes possible a cost reduction of as much as 65 percent. "The
Best of Sensors Expo Awards recognize products that we feel will
have the greatest and broadest impact on the future of sensor-based
design," said Barbara Goode, editor-in-chief, Sensors Magazine.
"Analog Devices is a well-recognized innovator in this arena. We
were wowed by the AD7745 because of the way in which it empowers
designers of high-performance instrumentation and sensing
applications." "The CDC was developed from a clear need by
instrumentation customers for an integrated solution that addressed
the lack of precision, high cost, and complicated nature of
previous capacitance solutions," said Dick Meaney, vice president,
precision converters, Analog Devices. "Analog Devices is honored to
receive this accolade from Sensors Magazine and we remain committed
to delivering high-performance converters that address specific
needs within targeted markets." Sensors Magazine
(www.sensorsmag.com), the leading sensor trade publication for more
than 21 years, and Sensors Expo & Conference are produced by
Questex Media Group. About the AD7745 Introduced in March of 2005,
the first three devices in the CDC family - the AD7745, AD7746 and
AD7747 - eliminated the constraints previously associated with
capacitance sensors, which are used to enable high-precision
measurements in space-constrained and power-sensitive applications
such as pressure monitoring and position sensing. While extremely
robust, accurate, and sensitive, capacitance sensors can be costly
and difficult to implement. By enabling higher accuracy (24-bit
resolution) and delivering complete on-chip analog functionality,
the CDC devices help designers of these reducing design effort and
external component costs. The CDC products leverage ADI's expertise
in high-precision sigma-delta technology and system integration by
combining 24-bit resolution, low noise of 5 aF (10-18) per root
hertz, and low power (1 mA max) with a complete range of on-chip
analog functions, including a high-performance, 24-bit, sigma-delta
analog-to-digital converter (ADC), a precision low-noise, low-drift
voltage reference and a temperature sensor. For more information on
