Sigma-Delta A/D Converters Improve Signal Quality Monitoring in Instrumentation, Energy and Healthcare Applications
June 08 2016 - 8:00AM
Business Wire
Analog Devices, Inc. today introduced a series of 24-bit
simultaneous sampling sigma-delta A/D converters for
wide-bandwidth, high-density instrumentation, energy and healthcare
equipment. The new AD7768 series includes a power scalable
modulator and digital filter on each channel to enable the
synchronized, precise measurement of both ac and dc signals in
instrumentation applications, including modular data acquisition,
audio test, and asset condition monitoring. The high throughput,
fast settling response, and simultaneous sampling of the AD7768
series enables faster test times, which reduces testing costs and
allows more efficient instrumentation design. The AD7768 series’
high channel count provides healthcare devices, such as clinical
vital signs monitoring equipment, with the means to significantly
expand channel density while maintaining low power and high input
bandwidth. The new converters also deliver improved power quality
monitoring through the ability to detect harmonic distortion over a
wider bandwidth for detection and diagnosis of grid imbalance. A
scalable, easy-to-configure layout also allows system designers to
save additional time and cost by using a single converter series
across multiple equipment platforms, performance points and
measurement ranges.

The 24-bit, 8-channel AD7768 and the 24-bit, 4-channel AD7768-4
have a 6-dB dynamic range advantage over the nearest competing
products and deliver the industry’s best integral non-linearity
(INL) performance across the widest available bandwidth, in
addition to achieving 10 times better offset, a 30 times reduction
in gain error, and a 2 times improvement in gain drift.
