Let's say the Open Loop Gain (AVOL) of two op-amps is 10V/mV and 10000 V/mV, respectively. The one with better performance will be used to build the signal-conditioning circuit (e.g. buffering, low-pass filter, etc.) for an analog-to-digital converter (ADC). How will the AVOL affect the performance of an AD circuit? Which op-amp should I choose, the one with higher or lower AVOL?
