As in the attached figure, the voltage at terminal A and B of AD7763 in our application can be -2.5V. Is this OK?
The input can be at the minimum of -2.5V at the terminals A and B. This is because – the output of the differential amplifier VoutA+ and VoutA- are always biased to 2.048V. –this means that this DC bias will feed back through the components RFB to the in input pins of the amplifier. This will DC bias the analog input to the amplifier to a value close to ground.
