ADA4051 Low-Power, Zero-Drift Operational Amplifier
Analog Devices' operational amplifier ideal for battery-powered applications
ADI's ADA4051 is a CMOS, micropower, zero-drift operational amplifier that utilizes an innovative chopping technique. This amplifiers features 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, this device offers 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 amplifier an ideal choice for battery-powered applications where high precision and low power consumption are important.
The ADA4051-2 is specified for the extended industrial temperature range of -40°C to +125°C.
