The AD865x family features the newest generation of DigiTrim® The AD865x family consists of high precision, low noise, low in-package trimming. This new generation measures and corrects distortion, rail-to-rail CMOS operational amplifiers that run the offset over the entire input common-mode range, providing from a single-supply voltage of 2.7 V to 5.5 V. less distortion from VOS variation than is typical of other rail-to- rail amplifiers. Offset voltage and CMRR are both specified and The AD865x family is made up of rail-to-rail input and output guaranteed over the entire common-mode range as well as over amplifiers with a gain bandwidth of 50 MHz and a typical the extended industrial temperature range. 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 The AD865x family can be used in communications applications, specified over the extended industrial temperature range such as cell phone transmission power control, fiber optic (−40°C to +125°C). networking, wireless networking, and video line drivers.
