Analog Devices Inc. ADA4051-1/ADA4051-2 Zero-Drift Amplifiers

Analog Devices ADA4051-1/ADA4051-2 Operational Amplifiers (Op Amps) are CMOS, micropower, zero-drift operational amplifiers based on an innovative chopping technique. The ADA4051-1/ADA4051-2 Op Amps provide a rail-to-rail input/output swing and have an extremely low-offset voltage when operating from a 1.8V to 5.5V power supply. Furthermore, these op amps offer high power supply rejection ratio (PSRR) and common-mode rejection ratio (CMRR) when operating with a typical supply current of 13μA per amplifier. The design of the ADA4051-1/ADA4051-2 Op Amps make the devices an ideal choice for battery-powered applications where high-precision and low-power consumption are required.
