PCM1822-Q1: Can I seperate AGND and DGND?

Can I use this type of single-end input, using 10uF and 1uF DC-block capacitor? How can PCM1820 know if input is single-end of diffirential?

the Thermal Pad below the chip is to be considered the Star point. The Analog connections of the Chips and external analog circuit is to be part of 1 plane that includes the Thernal pad,

If you wish to put digital components on another digital ground plane then make sure thiis plane conncts to the thermal pad at one point.

Ideally we prefer a single cupper pour for the entire circuit.

Circuit for single ended operation is correct
