Hello.
I'm sorry, this is my second thread on this subject but I'm puzzled about the concept of differential inputs.
I understand what it is and how it is implemented with two opposite signals that are summed together...?
What I find screwing up my thoughts is that in a ADC which power supply is a single supply between VCC and GND and has a 2.048V voltage reference has an input range of ±2,048V, how does it handle negative voltages without a negative supply?
Regards
