SSM2164

The SSM2164, THAT 2162 or V2164 IC is a quad voltage controlled amplifier (VCA) with 100 dB dynamic range and 0.02% THD.

History
Designed by Dave Rossum the SSM2164 is based on his 1979 design of the SSM2010.

Usage
Each VCA offers current input and output and a ground referenced –33 mV/dB control port. It will operate over a supply voltage range of ±4 V to ±18 V.
