ADI’s ADA2200 demodulator raises performance
threshold for low-power signal processing applications, while
reducing system complexity and board space.
Analog Devices, Inc. (NASDAQ: ADI) released today a synchronous
demodulator with the industry’s best combination of integration,
performance, flexibility and power consumption.
The ADA2200 uses ADI’s patent pending sampled analog technology
(SAT), developed at Lyric Semiconductor, Inc. (acquired by ADI in
mid-2011), and incorporates a configurable analog filter to enable
designers of portable and low-power instrumentation to maximize
battery life and perform precision magnitude and phase measurements
on analog signals in the presence of large noise sources. Compared
to traditional discrete implementations, this compact, integrated
solution reduces PCB area by up to 25 percent and provides
designers with a higher degree of flexibility, reducing system
design and optimization time and facilitating circuit design reuse
across multiple sensors, products and platforms.

The low-power (390-uA at 3.3V and fCLK = 500 kHz) and
rail-to-rail operation of the ADA2200 make it ideal for advanced
battery-powered and low-voltage systems serving medical, industrial
and communications markets and can be used in a wide variety of
applications including impedance measurement, gas detection, air or
fluid analysis, strain gauges and proximity measurement.
About The ADA2200 and Patent Pending SAT TechnologyThe
ADA2200 features a highly integrated analog signal chain, including
a configurable infinite impulse response (IIR) filter, low-pass
finite impulse response (FIR) 1/8x decimation filter, mixer with
0°/90° phase selection, reference clock and A/D converter driver
output. Optimized for input sampling rates up to 1 MHz, the ADA2200
enables demodulation of signal input bandwidths to 30 kHz, achieves
0.009º phase detection sensitivity and operates over a -40°C to
+85°C temperature range.
ADI’s proprietary SAT technology uses charge sharing among
capacitors to perform “digital-like” computations in the analog
domain. By processing the signal entirely in the analog domain,
this analog-in, sampled-analog-out device reduces A/D converter
sample rates, lowering A/D converter power consumption by up to 87
percent and offloads computationally heavy tasks from the digital
processor or microcontroller. This allows designers to simplify
their system architecture, shorten development time, and reduce
system size and power consumption.
