Slightly OT: DAC Questions

[Gavin Muir]

Hi All,

	Just pondering a MIDI to CV converter, and examining a few schems. Most I
have seen use 8 bit processors with 8 bit DACs, and I have heard much talk
about using higher quality DACs. 

	Now, as I am new to the Digital realm, exactly how do you benefit from
hooking up a 12 bit DAC to an 8 bit processor, and how would you go about
doing such a thing as there will only be 8 data bus outputs from the uP?

Cheers and thanks,
Gavin.
