GENERAL DESCRIPTION
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 µV across common mode from a 5 V supply. It also features
low noise—4.5 nV/√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®
in-package trimming. This new generation measures and
corrects the offset over the entire input common-mode range,
providing less distortion from VOS 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 (−40°C to +125°C).
