Voltage Controlled Amplifiers (VCA)

Hands-down the most widely used VCAs in both pro and MI applications, THAT Corporation's 2180 and 2181 series provide extremely wide dynamic range and control range, very low distortion (lowest in the trimmable 2181 series), low noise, and the all-important "deci-linear" control whereby linear changes in control port voltage result in decibel-wise changes in signal gain.

Make sure to check out THAT's extensive Design Notes for dozens of application and circuit ideas!
