AD7729 - Dual Sigma-Delta ADC with Auxiliary DAC

Analog Devices

General Description

This monolithic 3 V CMOS device is a low power, two-channel, input port with signal conditioning.

The receive path is composed of two high performance sigma-delta ADCs with digital filtering.

A common bandgap reference feeds the ADCs.
