ADA4051-1AKSZ-R2 GENERAL DESCRIPTION

The ADA4051-1/ADA4051-2 are CMOS, micropower, zero-drift operational amplifiers utilizing an innovative choppingtechnique. These amplifiers feature rail-to-rail input/outputswing and extremely low offset voltage while operating from a1.8 V to 5.5 V power supply. In addition, these amplifiers offerhigh power supply rejection ratio (PSRR) and common-moderejection ratio (CMRR) while operating with a typical supplycurrent of 13 μA per amplifier. This combination of featuresmakes the ADA4051-1/ADA4051-2 amplifiers ideal choices forbattery-powered applications where high precision and lowpower consumption are important.The ADA4051-1/ADA4051-2 are specified for the extendedindustrial temperature range of −40°C to +125°C. The ADA4051-1amplifier is available in 5-lead SOT-23 and 5-lead SC-70 packages.The ADA4051-2 amplifier is available in an 8-lead MSOP and an8-lead LFCSP.The ADA4051-1/ADA4051-2 are members of a growing seriesof zero-drift op amps offered by Analog Devices, Inc.
