This document introduces Analog Devices' low power operational amplifier products and provides pin configuration diagrams and specifications for different package forms.
The AD8622 and AD8624 are precision, low power, rail-to-rail output operational amplifiers available in dual (AD8622) and quad (AD8624) channel configurations. They feature extremely low bias voltage (125 µV maximum) and low power consumption, with a typical supply current of 215 µA per amplifier. These devices are designed for applications requiring high DC accuracy and low noise, such as portable instrumentation, laser diode control loops, and medical instruments.
