APPLICATIONS

for electronic music

General Description

The AS3364 is a quad general purpose voltage linearly controlled VCA intended for such applications as

voltage controlled amplifiers, filters, and waveform generators. Each VCA independently provides linear

control scaling over greater than a 100 dB range. Complete with virtual ground summing inputs, wide voltage

compliance current outputs, and control inputs referenced to ground, the AS3364 requires exceptionally few

external components and is extremely easy to use.

Because of its inherent ultra-low control feedthrough, no trimming is required. Added to these features are

exceptionally low noise, wide bandwidth, and operation down to ± 3 volts, making the AS3364 a real cost

saver in most applications requiring variable transconductance amplifiers.

AS3364 pinout allows simple replacement of AS2164 (adding just one capacitor to Vref) witch simplify circuit

design with linear control.
