FET Input Amplifiers

Analog Devices' High Speed (>50MHz) FET input op amps or FastFET™ provide high input impedance and ultra low input bias currents for high speed applications. The majority of our FET input op amps feature wide supply ranges from 5 to ±12V or higher and feature rail-to-rail outputs enabling wide dynamic range.
