Working Principle

The AD797ARZ-REEL7 is a differential amplifier, based on the common emitter and common source amplifier topology. This architecture provides a low-noise, low-distortion and low-power operation in which a varying differential voltage applied to the input stages causes a change in the current flow between the two input transistors. This current flow then passes through a voltage feedback circuit and generates an output current through the output stage. This output current is then converted into a voltage signal by a gain stage, provided by the feedback network and current mirror.

The AD797ARZ-REEL7 includes an adjustable common-mode input range of up to ±20V and it is specifically designed and optimized for best performance at low-noise, low-distortion and low-power operation. The amplifier is designed to achieve excellent linearity over a wide input and output range, low power consumption, high power supply noise immunity and fast settling times.
