I'm using AD7771 with an fully differential AMPOP. The ADC would be supplied with 3.3 V, Vref- would be tied to ground and Vcm would provide a bias for the AMPOP. In the ADD7771 analog inputs, there would be something like this:
Being Ain+ in red, Ain- in blue and Ain+ - Ain- in black.
Can the AD7771 work with this signal, given that the differential has negative values and i'm only working with single supply?
