6.3.2 Analog Input

The analog inputs of ADC3910Dx and ADC3910Sx supports differential and single-ended configuration, with support for AC coupling and DC coupling. Analog inputs are designed for an input common mode voltage of 1.25V which must be provided externally on each input pin. DC-coupled input signals must have a common mode voltage that meets the device input common mode voltage range.

The ADC3910Dx and ADC3910Sx has buffered analog inputs which eases design by isolating the input from the ADC sampling operation.
