Analog Devices, Inc - AD7176-2 ADC Achieves Twice the Speed - 6 December 2012

Introducing a new multiplexed 24-bit sigma-delta A/D converter that doubles the throughput rate while dissipating less power.

AD7176-2 is a fast settling, highly accurate, high resolution, multiplexed Σ-Δ analog-to-digital converter (ADC) for low bandwidth input signals.

The AD7176-2 can be designed into circuits together with ADI's single-supply, low-noise, low-offset AD8656 CMOS amplifier and single supply, attenuating input stage, AD8475 differential driver.
