what is the relation bewteen input and output for adar7251? the releation is output=vin/(2^16-1)?
Please note the ADAR7251 has default gain of +9dB. This means that differential input of around 2Vp-p would give you full scale at the ADC output or 0dBFS. The ADC output is 16 bit and 2's complement. Please note the MSB is a sign bit. The output would vary between 0x7FFF to 0x8000. The ADC resolution would be 5.6V/ (2^16-1).
