ADA4051-2ACPZ-R7

1.8 V ，微功耗，零漂移，轨到轨输入/输出运算放大器 1.8 V, Micropower, Zero-Drift, Rail-to-Rail Input/Output Op Amp

Product Details

The ADA4051-1/ADA4051-2 are CMOS, micropower, zerodrift operational amplifiers utilizing an innovative chopping technique. These amplifiers feature 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, these amplifiers offer 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 ADA4051-1/ADA4051-2 amplifiers ideal choices for battery-powered applications where high precision and low power consumption are important.

The ADA4051-1/ADA4051-2 are specified for the extended industrial temperature range of −40°C to +125°C. The ADA4051-1 amplifier 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 an 8-lead LFCSP.

The ADA4051-1/ADA4051-2 are members of a growing series of zero-drift op amps offered by Analog Devices, Inc.
