Sigma-Delta A/D converters improve signal quality monitoring

摘要

Analog Devices Inc has 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 synchronised, precise measurement of both AC and DC signals in instrumentation applications, including modular data acquisition, audio testing 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.
