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 V 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.
