Alfa Rpar - AS3360A - Dual Voltage Controlled Amplifier

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.

Features:
• two independent VCAs in a single 14 pin package simple to use - few external components required
• exceptionally low control feedthrough without trimming: 10mV maximum - 10 V.P.P. output
• low noise: -110 dB typical
• no trimming required
• summing node signal inputs
• current outputs capable of swinging to within 1,5V of each supply
• linear and exponential control

Applications:
• for electronic music
