Working Principle

The AD8138AR-REEL is an integrated special purpose linear amplifier that operates by applying a signal through an input port to an amplifier stage. The signal is then processed and amplified through a number of gain stages, each having its own output stage. Each gain stage produces a gain output level that is dependent upon the bias voltage applied to its input port.The output of each gain stage is combined and fed through a proportional gain stage that provides the final gain rating at the amplifier’s output port. The total gain is a combination of the gains of each gain stage. The AD8138AR-REEL is designed to provide high gain, low distortion, and wide-bandwidth performance when operated over a wide range of operating conditions. The device offers excellent linearity, low input bias current and low noise. It is also designed for very low power consumption and is suitable for various applications including sensitive equipment in audio, video and communication systems.
