ALFA RPAR AS3310-DIL Voltage Controlled Envelope Generator (DIL-16)

 Loading product data...

The ALFA RPAR AS3310 is a self-contained, precision ADSR type of envelope generator intended for electronic music and other sound generation applications. It is pin-for-pin compatible with the CEM3310.

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.

On the negative power output, there is an internal Zener diode at 7.4 volts ±10%, which allows the chip to supply a maximum voltage of ±15V with a current-limiting resistor REE, and a minimum positive supply voltage of +11 volts and a minimum negative supply voltage of -5 volts.

We also have this device in an SMT package.
