GENERAL DESCRIPTION
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 can be used in communications applications,
such as cell phone transmission power control, fiber optic
networking, wireless networking, and video line drivers.
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 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).
