AS3363 contains three VCA blocks, which are intended for use in musical synthesizer applications (VCA blocks, voltage polarizer, multiplexers, morphing, ring modulators etc.). Distinct feature of AS3363 is control input that controls attenuation of output current - thus providing possibility function of double multiplication input signal on two control signals.


  • Three VCA blocks with a wide range of functions
  • Including 4-quadrant multipliers
  • Two linear controls for each VCA
  • Simple signal mixing
  • Can combine high impedance outputs
  • High attenuation (-100 dB)
  • Simplifies multiplexer design
  • Low current consumption of 3 mA typ at ±12V
