This monolithic 3 V CMOS device 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 AD7729 is available in a 28-lead TSSOP package or a 28-lead SOIC package.
