This ADC has programmable gain instrumentation amplifier that can accept full scale differential inputs. As per my understanding we can program the gain when using differential signals.But in my design I am using eight single-ended input channels, so in this case what will be the PGIA setting? will it be a default condition i.e. +/-20.48V (PGIA GAIN=0.2) ?
PGIA range is configurable and can be set depends on your specified input. By default PGIA is set to +/-20.48V.
