AD8651/AD8652 is a 50MHz, precision, low distortion, low noise CMOS amplifier manufactured by Analog Devices.
The AD8651/AD8652 are high‑precision, low‑noise CMOS operational amplifiers designed for demanding communication, audio, and video applications. They feature rail‑to‑rail input and output, a gain‑bandwidth product of 50 MHz, and typical offset voltage of 100 pV.
Key specifications include a low noise density of 4.5 nV/√Hz, input bias current of 1 pA, and single‑supply operation from 2.7 V to 5.5 V. The devices are offered in 8‑lead MSOP and SOIC packages and are rated for operation over –40 °C to +125 °C.
