The AS3310 is a self-contained, precision ADSR type envelope generator, pin to pin compatable with CEM3310.


  • Large Time Control Range: 50,000:1 min
  • 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: +11V ÷ +15V
  • CEM 3310 replacement​

This chip is fully redesigned in order to improve stability and eliminate some native faults and it comes in DIP-16, SOIC-16 for more compact designs.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.

NB! For 100+ pcs and/or in SOIC, QFN cases, please send an inquiry to Alfa RPAR: alfa@alfarzpp.lv
