Analog Control Variable Gain Amplifiers (VGAs)

Analog Devices voltage controlled variable gain amplifiers (VGAs) provide continuous gain control over a wide dynamic range for a variety of audio and optical frequency bands. Our VGAs improve the dynamic range of a circuit by allowing users to adjust a signal’s amplitude in real time, which is invaluable for ultrasound, speech analysis, radar, wireless communications, and instrumentation-related applications, all of which commonly use analog control VGAs.

In addition to analog control VGAs, we also offer a portfolio of digital controlled VGAs to provide you with discrete levels of gain control over a fixed number of control bits. By providing both analog control VGAs and digital control VGAs, we offer solutions for managing dynamic range that are easy to control digitally and provide smooth transition between gains.
