This new generation measures and corrects The AD865x family consists of high precision, low noise, low the offset over the entire input common-mode range, providing distortion, rail-to-rail CMOS operational amplifiers that run less distortion from V variation than is typical of other rail-to- OS from a single-supply voltage of 2.7 V to 5.5 V. 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 V across common mode from a 5 V The AD865x family is offered in the narrow 8-lead SOIC supply. It also features low noise4.5 nV/Hz. 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 (40C to +125C). networking, wireless networking, and video line drivers.
