About analog input voltage for PCM1804.
The datasheet says as following.
Absolute Maximum Ratings: 10Vp-p(differential input)
Recommend Operating conditions : 5Vp-p(differential input)
If they use between 5Vp-p and 10Vp-p.
Is there any problem?
Let me know any concern about it.
Where do you see the 10Vp-p in the data sheet?
You definitely should attenuate the signal to fall within the recommended range of 5Vp-p.

What kind of output would be expected under following condition?
Input to Vin R+ : sine wave 0.75v-4.25v
Input to Vin R- : sine wave 0.75v-4.25v
(Inverted of Vin R+ input)
I have asked one of my colleagues to help you with this question.
We hope to get reply from you soon.
Because the VCOM internally is still 2.5V as well, there is potential for is clipping and other issues if the input voltage exceeds that total 5V. So with a input voltage 4.25V and a VCOM of 2.5V this is still not recommended.
Unfortunately we do not have performance data for operation that exceeds the specification.
