GENERAL DESCRIPTION
The ADA4051-1/ADA4051-2 are specified for the extended The ADA4051-1/ADA4051-2 are CMOS, micropower, zero- industrial temperature range of −40°C to +125°C. The ADA4051-1 drift operational amplifiers utilizing an innovative chopping amplifier is available in 5-lead SOT-23 and 5-lead SC-70 packages. technique. These amplifiers feature rail-to-rail input/output The ADA4051-2 amplifier is available in an 8-lead MSOP and an swing and extremely low offset voltage while operating from a 8-lead LFCSP. 1.8 V to 5.5 V power supply. In addition, these amplifiers offer The ADA4051-1/ADA4051-2 are members of a growing series high power supply rejection ratio (PSRR) and common-mode of zero-drift op amps offered by Analog Devices, Inc.
