General Description

The AD8372 is a dual, digitally controlled, variable gain amplifier (VGA) that provides precise gain control, high IP3, and low noise figure.

The excellent distortion performance and moderate signal bandwidth make the AD8372 a suitable gain control device for a variety of multichannel receiver applications.

For wide input dynamic range applications, the AD8372 provides a broad 41 dB gain range.
