3 V, Dual Sigma-Delta ADC With Auxiliary DAC

This monolithic 3 V CMOS device AD7729 is a low power, two-channel input port with Signal Conditioning The receive path is com- posed 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 auxil- iary functions CAN be accessed via the auxiliary port (ASPORT). This device is available in a 28-lead TSSOP package or a 28-lead SOIC package. By Analog Devices, Inc.
