GENERAL DESCRIPTION

The AD7783 is a complete analog front end for low frequency measurement applications. The 24-bit sigma-delta ADC contains one fully differential input channel that can be configured with a gain of 1 or 16 allowing full-scale input signal ranges of ±2.56 V or ±160 mV from a +2.5 V differential reference input. It also contains two 200 mA integrated current sources.
