Function Generator

I am after a basic schematic design for a Function Generator, that will give Square, Sine, and Sawtooth waveforms, be amplitude variable, from 50mV to 5 V, and also frequency variable 3kHz to 30Khz. I have some concepts already, but looking for one that utilises op-amps, for all functions. ie: u741, ca3130, or package of quad amps[/b]

Somewhere on https://www.epanorama.net you will find a schematic that uses the Maxim MAX038 chip.

this is exactly what you're looking for.

p.s- Maxim provides free samples

U can use XR8038 IC. Its specially designed fot that purpose.
