I've been told that leaving pins that aren't being used and leaving simply disconnected is a bad idea. That will increase power consumption, noise, etc. I know how to do it in a op amp, but I'm having some difficulty with this DAC chip. I won't use the S/PDIF function.

I'm guessing that the S/PDIF input should be tied to ground, should I take any other precaution? And what about the output? If I do the same to it, won't that possibly blow the chip due to overcurrent, or create noise of some kind? Should it be connected with a resistor? A capacitor in parallel? How should it be done?
