PCM1803A - DC Signals

Hello,

We are considering using the PCM1803A, and will have roughly 3Vp-p DC signals coming in most of the time.  Reading another forum post helps, but doesn't answer everything we need....

If we use the part in BYPASS mode, will the ADC stay locked, or could we experience drift?

If we don't use an AC cap, we have 5Vcc and 3Vdd, what is the range we should expect (i.e. 1V is 000, 4V is FFF)?

Finally, we also have a scenario where we will have a 10kHz AC signal coming in.  We believe that should still work with out the blocking cap in place.  Is that correct?

Thank you!
