QWhat is a zero-drift amplifier?
AA zero-drift amplifier is an amplifier with offset voltage drift close to zero.
It continuously self-corrects for any dc errors, achieving ultralow level of
offset voltage and drift due to time and temperature. Common features of a
zero-drift amplifier are ultralow offset voltage and drift, high open-loop
gain, high power supply rejection, high common-mode rejection, and no 1/f
