The AS3320 is a high performance voltage-controlled four-pole filter modelled after the CEM3320, with on-chip voltage-controllable resonance. The chip can be configured as an lowpass, highpass, bandpass, or all pass filter. It has an exponential (V/Oct) frequency control input which can cover more than ten octaves with little control voltage feedthrough. The Resonance CV allows control of the resonance from zero to low distortion oscillation. For more demanding applications, further trimming can improve control voltage rejection. Each filter section is fully temperature compensated and has consequent low warm-up drift.
