AD7729 Dual Sigma-Delta ADC with Auxiliary DAC

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. A control DAC is included for such functions as AFC. The auxilia.
