mic input to AIC26

 

Regarding the table on page of the AIC26 datasheet, under the "Microphone Input to ADC" section.

The DS says:

Picture (Enhanced Metafile)

I translate the 0.707Vrms to 2.0Vpp input range.  I've been assuming a 2.0Vpp input capability for years.  I was just re-reading the DS and the 1.35V concerned me.  Could you clarify what this means?  Is the input forced to a 1.35V bias which would mean a sine wave couldn't use the 2.0Vpp range since it's unbalanced on the high side 1.35V as opposed to 1.0V.  thanks
