AS3360, AS3360A-Dual Voltage Controled Amplifier
( VCA ) |
The AS3360, AS3360A 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 (AS3360A). 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 and wide bandwidth making
the AS3360 a real cost saver in most applications requiring variable
transconductance amplifiers.
AS3360A benefits from internal bandgap
reference which improves stability of reference voltage and output
current of VCA and improved level of attenuation of output current at
zero control voltage.
