I am using AD7175-5 analog to digital converter for my application, in my application analog input is bipolar +/-0.5V (level shifted AC sine with 1kHz). I am giving +/-2.5V at AVDD1 and AVSS, AVDD2 is 2.5V, IOVDD is 3.3V, reference+ is 1.25V w.r.t reference-. To convert bipolar analog input does ADC require bipolar reference?
