The ASM316 comprises 2 LIN/LOG VCAs.


In July 2002, EDN Network published an article by Mike Irwin on the application of op-amps to linearise the response of a voltage controlled attenuator built around the Analog Devices SSM2164.


In September 2003 Phillip Gallo published a design for a Dual LIN/LOG VCA utilizing this design idea, and the ASM316 realises that design in a EuroSynth module.


With the CV level control at maximum, a 0V to +2V5 signal will raise the gain of the VCA from -100dB of attenuation to 0dB while increasing the voltage from +2V5 to +5V will further increase the gain from 0dB to +20dB.
