Waveform Generator with ICL 8038CCPD

Hosted circuit

That circuit is based on a 14-pin DIL IC capable of producing sine, square, triangular, sawtooth and pulse waveforms of high accuracy and stability. The frequency may be selected to be from 0.001Hz to 1Mhz, Frequency modulation and sweeping can be accomplished with an external voltage and the frequency can be programmed digitally by resistors or capacitors. Sweep range can be up to 40:1 or 1000:1 with a little less quality.

The circuit shows a sine, triangle and square wave generator. SW1 is the range switch, SW2 sets the waveshape, VR4 sets the output level and VR3 is the frequency control. VR1 and VR2 should be adjusted to give minimum distortion of sine wave.

Hey boy... I am working on functiona generator with ICL8038 (NTE continues manufacturing as NTE864). I am following this diagram: http://www.todo-electronica.com.ar/gen_fun_diseno.htm ...

... but I have not had success with the generation of signals and I could not make the simulation in Multisim, Proteus, OrCad because they do not contain the IC. Brother ... If I can give the simulation or material you have on your circuit I would very much. Thaks you!
