The ADA4051-2ARMZ is a micropower zero-drift dual Operational Amplifier with rail-to-rail input/output. The amplifier utilizing an innovative chopping technique. This amplifier feature rail-to-rail input/output swing and extremely low offset voltage while operating from a 1.8 to 5.5V power supply. In addition, this amplifier offer high power supply rejection ratio (PSRR) and common-mode rejection ratio (CMRR) while operating with a typical supply current of 13μA per amplifier. This combination of features makes the ADA4051-2 amplifier ideal choices for battery-powered applications where high precision and low power consumption are important.
