General Description

The AS3360 is a dual general purpose voltage controlled transconductor intended for such applications as voltage

controlled amplifiers, filters, and waveform generators. Each transconductor independently provides both linear and

exponential 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 AS3360 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 AS3360 a real cost saver in

most applications requiring variable transconductance amplifiers.
