The XR-2206 from Exar© is a great IC because, with a few components, it makes it possible to build a circuit that generates analogically various waveforms with a frequency from 0.01Hz to 100MHz. This capability allows you to build quite easily a function generator useful to test audio devices and all the circuits that require a low frequency input.

By exploiting the characteristics of the IC, I provided the PCB with two outputs: one suitable for testing analogue circuits, one for testing digital ones.
