GENERAL DESCRIPTION The AD743 is an ultralow noise, precision, FET input, monolithic
operational amplifier. It offers a combination of the ultralow voltage noise generally associated with bipolar input op amps and
the very low input current of a FET input device. Furthermore,
the AD743 does not exhibit an output phase reversal when the
negative common-mode voltage limit is exceeded.
The AD743’s guaranteed, maximum input voltage noise of …
