Here is a first attempt at an XR 2206 function generator built on a breadboard.
Range is 1Hz to 100kHz. Produces square, sine, and triangle waves.
The square waves are relatively clean; the sine and triangle waves have some distortion in them at the peaks. I'm hoping that soldering the circuit onto a board will eliminate some of the instabilities (though the 2206 is known to have some inherent problems).
So far the output seems sensitive to impedance changes. I'm hoping hooking it up to an op amp buffer to fix that problem.
The schematic I used is here:
