You can even make an ÃŒber cheap awful sounding 8 bit "soundcard" like that and drive it by sending 8 bit sample values directly to the

direct to appropriate information regarding this?
Christian pointed me here: http://en.wikipedia.org/wiki/Covox which is an (ancient) commercial implementation of the idea and tells you pretty much everything you need to know. The key is to get very accurately matched resistors. It's a lot of fun actually, to build yr own soundcard that can be used by popular software such as wolfenstein 3d and fasttracker II. ;)
Best,
