ADA4051-2ARMZ

精密放大器 1.8V RRIO Dual Zero-Drift

1.8 V, Micropower, Zero-Drift,  Rail-to-Rail Input/Output Op Amps

GENERAL DESCRIPTION ADA4051-2ARMZ

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 common-mode rejection ratio (CMRR) while operating with a typical supply current of 13 μA per amplifier. This combination of features makes the ADA4051-1/ADA4051-2 amplifiers ideal choices for battery-powered applications where high precision and low power consumption are important.
