AS3394E

The ALFA AS3394E is a complete analog music synthesizer voice-on-a-chip intended for software control by a microprocessor system. PDIP-24. Included inside the compact 24 pin package is fully temperature compensated, wide range, voltage controlled oscillator providing sub-oscillator, triangle, saw-tooth, and pulse waveforms; a voltage controlled mixer for adjusting the balance between the internally generated VCO waveforms and any external signal; a dedicated four-pole low-pass voltage controlled filter with voltage controlled resonance; a modulation amount VCA for modulating the filter frequency by the triangle waveform output of the VCO; and a final VCA for allowing the output to be enveloped. Envelope control for both the VCF and final VCA may be provided by either a hardware envelope generator such as The ALFA AS3310 or through software.
