GENERAL DESCRIPTION
The ADA4051-1/ADA4051-2 are CMOS, micropower, zerodrift operational amplifiers utilizing an innovative chopping technique. These amplifiers feature rail-to-rail input/output swing and extremely low offset voltage while operating from a 1.8 V to 5.5 V power supply. In addition, these amplifiers offer high power supply rejection ratio (PSRR) and ...
