[sdiy] Replacing DACs

[john mahoney]

nate,
You needn't replace a DAC just to drop the bit resolution. Grounding the
desired low bits should suffice. To make a 12-bit DAC act like an 8-bitter,
just ground the 4 low bits (or switch them out of the circuit).

Logically, the above is accurate. Electrically? I'm not responsible if you
damage your gear.
