About a value of Single-Ended input voltage on ADAU1977

I have a question.


On page 4 of Rev.C ADAU1977 data sheet, it says that QUASI DC INPUT (Single-Ended Input Voltage) is 5 V peak.


However, the attenuator's operating voltage is 3.3V.

It seems for me that an input signal shape would change if under the condition.


I have read the explanation "Line Input Unbalanced or Single-Ended AC-Coupled Case"on p.19 but could not find a clue.


Could anyone help me out?


Thank you in advance.
