Alex41,

How much noise are we talking about here?  1/2 volt?  1/4 volt?  Smaller?  Larger?  A 12 bit DAC running at 5 volts means each step is roughly 1 millivolt.  What is the setup you're working on?  A breadboard with long wires everywhere?  If you don't have a PCB with a ground plane, don't expect a clean output from a hi-rez DAC.  The funkier your setup is, the funkier the output will be.

Thanks,
PeterM
