AS3363

The ALFA AS3363 (PDIP-16) contains three VCA blocks, which are intended for use in musical synthesizer applications (VCA blocks, voltage polarizer, multiplexers, morphing, ring modulators etc.). VCA1 and VCA2 implement function of controlling amplification and sign of output signal (voltage polarizing - changing sign and amplitude through 'silence'). Additional control input controls attenuation of output current - thus realizing function of double multiplication input signal on two control signals. VCA3 block has additional feature - possibility of control/mixing of two input signals. Such solution gives vast opportunities in designing new synth solutions.
