1 pcs. Alfa Rpar AS3340A VCO IC DIP16 replaecemt for Curtis CEM3340

The IC Alfa Rpar AS3340A is a voltage-controlled oszillator module that was used in analogue synthesizers in the 1980s.

Mechanical Description of AS3340A:

This AS3340A is housed in a DIP 16 package and is designed for  classic through hole mounting on a circuit board. Use of a socket is possible. The IC has 2 x 8 connecting pins with grid of 2.54 mm x 7.62 mm.
 

Benefits of advanced chip typ:

AS3340A are improved versions of AS3340. AS3340A and have much more output frequency stability against Vcc and VEE . Frequency stability can be improved If external reference voltage (with level approximately 1/3 Vcc) is connected to pin 9 (Soft Sync. Input). AS3340A benefits from improved symmetry of rising and falling edge of triangle signal (approx.. 50%).
AS3345 benefits from additional Meander Output. Meander edge starts when Triangle changes it’s direction. These feature gives additional opportunities for design.

Technical description of the AS3340A:

The AS 3340 is a completely self contained, precision voltage controlled oscillator, featuring both exponential and linear control scales and up to four buffered output waveforms: triangle, sawtooth, square, and pulse with voltage controllable pulse width. Full temperature compensation makes these VCOs extremely stable, and eliminates the need for a temperature compensation resistor. The highly accurate exponential and linear control inputs are virtual ground summing nodes, allowing multiple control voltages to be mixed within the device itself.
