The AD8651 is a high precision, low noise, low distortion, rail-to-rail CMOS operational amplifier that runs from a single supply voltage of 2.7 V to 5 V. The AD8651 is a rail-to-rail input and output amplifier with a gain bandwidth of 50 MHz and a typical voltage offset of 100 uV across common mode from a 5 V supply. It also features low noise--4.5 nV/\Delta Hz. The AD8651 can be used in communications applications, such as cell phone transmission power control, fiber optic networking, wireless networking, and video line drivers. The AD8651 features the newest generation of DigiTrim(R) in-package trimming. This new generation measures and corrects the offset over the entire input common-mode range, providing less distortion from V OS variation than is typical of other rail-to-rail amplifiers. Offset voltage and CMRR are both specified and guaranteed over the entire common-mode range as well as over the extended industrial temperature range. The AD8651 is offered in the 8-lead SOIC package and the 8-lead MSOP package. It is specified over the extended indus-trial temperature range (-40oC to +125oC).
