The AD7731 is a complete analog front-end for process control applications. The device has a proprietary programmable gain front end which allows it to accept a range of input signal ranges including low-level signals directly from a transducer. The sigma delta architecture of the part consists of an analog modulator and a low-pass programmable digital filter, allowing adjustment of filter cutoff, output rate and settling-time.
