xr2206

I've already posted this to Bert Schiettecatte (sorry that you'll recieve
this message twice).

The xr2206 is a very fine sine generator (THD,total harmonic distortion is
smaller dan 1% I believe).
It has an am and fm modulation input, especially the fm input is very cool.
I think aphex twin used a similar device on ventolin (I care because you do
cd) the tone in the beginning that deformes to one big noise.
I used it with my bass and it is worse than everything you've ever heard.
Another ic is the ICL 8038 this is more versatile than the XR but it has a
larger THD (around 3 to5%). The advantage of the icl 8038 is that it
produces triangle square and sine simultaniously it is also cheaper.
The pin layout etc can be found in electronics books or on the internet, go
to the exar site (if there exists one) or try chipdir as a searchstring.
