AS3330

The AS3330 is a dual general purpose voltage controlled amplifier. The chip is Alfa's modern pin-for-pin compatible clone of the CEM3330 dual voltage-controlled amplifier. It can also be used to build voltage-controlled filters and waveform generators.

Each transconductor independently provides both linear and exponential control scaling over greater than a 100dB range. Complete with virtual ground summing inputs, wide voltage compliance current outputs, and control inputs referenced to ground, the AS3330 requires very few external components and is extremely easy to use.
