GENERAL DESCRIPTION
The AD865x family 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 AD865x family consists of high precision, low noise, low
distortion, rail-to-rail CMOS operational amplifiers that run
from a single-supply voltage of 2.7 V to 5.5 V.
The AD865x family is made up of rail-to-rail input and output
amplifiers 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 AD865x family is offered in the narrow 8-lead SOIC
package and the 8-lead MSOP package. The amplifiers are
specified over the extended industrial temperature range
(−40°C to +125°C).
The AD865x family can be used in communications
applications, such as cell phone transmission power control, fiber
optic networking, wireless networking, and video line drivers.
