Overview
The AD8367ARU-REEL7, produced by Analog Devices Inc., is a high-performance variable gain amplifier designed for use in a wide range of applications requiring precise gain control. This component utilizes Analog Devices’ patented X-AMP® architecture, which ensures accurate gain control with a 45 dB span and a 3 dB bandwidth of 500 MHz. It operates as a single-ended, IF amplifier and can be configured as either a traditional VGA or an AGC amplifier using the built-in rms detector.
