The AS3310 is a self-contained, precision ADSR type of envelope generator intended for electronic music and other sound generation applications.
Manufacturer: ALFA RPAR

Attack, decay and release times are exponentially voltage controllable over a wide range, and the sustain level is linearly voltage controllable from 0 to 100% of the peak voltage Vp. All four control Inputs are Isolated from the rest of the circuitry so that the control pins of tracking units may be simply tied together.


  • Large Time Control Range: 100,000:1 
  • Full ADSR Response
  • True RC Envelope Shape
  • Exceptionally Low Control Voltage Feedthrough: 90µVmax
  • Accurate Exponential Time Control Scales
  • Isolated Control Inputs
  • Good Repeatability and Tracking Between Units Without External Trim
  • Independent Gate and Trigger
  • Wide power supply range:
       negative rail: -15V ÷ -9V (via external resistor)
       positive rail: +11,5V ÷ +15V
