Like most obsolete parts from the 1980s, these are rare to find now. Most of what are on the market are chinese copies. Apparently they do work, but not sure how good they are.
The design of the original IC was good in theory, but the practical side of them wasn’t that great.

I don’t know when the XR2206 went out of production but apparantly it has. And all the cheap diy frequency generator kits from China use copies that aren’t very good or up to spec.
But can you still find og 2206′s? In that case, are there specific markings/letters to look for? I’m just scared of buying trash even if it’s not a lot of money wasted.

Function generator without special generator IC

Improved DIY Function generator project
https://www.gadgetronicx.com/improved-diy-function-generator/

a DIY Function generator that can produce Square, Sine and Triangle wave with adjustable frequency. This project is a improvised version of DIY function generator which was published in our website earlier. Unlike the previous version, this FG comes with logarithimic sine wave converter and improved efficiency.

#97 Simple function (signal, waveform) generator
https://www.youtube.com/watch?v=LTe74zH9A6E

XR2206 Function Generator Project – Build a cheap, simple function (signal, waveform) generator.

Here’s an uber simple project for generating square waves, sine waves and triangle waves, ideal for general electronics use and for use in Arduino projects too. A simple project like this is also ideal for electronics beginners, with limited soldering skills.
