AD840 Overview
The AD840 is a member of the Analog Devices’ family of wide bandwidth operational amplifiers. This high speed/high precision family includes, among others, the AD841, which is unitygain stable, and the AD842, which is stable at a gain of two or it ideal for DAC and ADC buffers, line drivers and all types of video instrumentation circuitry. The AD840 is truly a precision amplifier.
