Alfa Rpar AS3360A VCF IC DIP14

1 pcs. Alfa Rpar AS3360A VCA IC DIP14 replacement for Curtis CEM3360

The IC Alfa Rpar AS3360A is a voltage-controlled amplifier module that was used in analogue synthesizers in the 1980s. The AS3360A is pin-compatible with the Curtis CEM3360

Mechanical Description of AS3360A :

This AS3360A is housed in a DIP 14 package and is designed for  classic through hole mounting on a circuit board. Use of a socket is possible. The IC has 2 x 7 connecting pins with grid of 2.54 mm x 7.62 mm.
 

Difference between Standard and Advanced chip typ:

AS3360A benefits from internal bandgap reference which improves stability of reference voltage and output current of VCA and improved level of attenuation of output current at zero control voltage.
 

Technical description of the AS3360A:

The AS3320 is a high performance voltage controlled four-pole filter with on-chip voltage controllable resonance IC. The four independent sections may be interconnected to provide a wide variety of filter responses, such as low pass, high pass, band pass and all pass. A single input exponentially controls the frequency over greater than a ten octave range with little control voltage feedthrough. Another input controls the resonance in a modified linear manner from zero to low distortion oscillation. For those demanding applications, provision has been made to allow trimming for improved control voltage rejection. Each filter section features a variable gain cell which is fully temperature compensated, exhibits a better signal-to-noise ratio and generates its low distortion predominantly in the second harmonic. The device includes a minus two volt regulator to ensure low power dissipation and consequent low warm-up drift.

Technically, the IC may differ slightly from the original. When replacing a Curtis CEM3360, the entire instrument must be recalibrated.

The CEM3360 was used in Oberheim and Sequential Circuits Synthesizern..
