Is the schematic correct ?  the two outputs are connected  and the two inputs

Where do I find the other end of "FILTER OUT" ?

    Hello izhmel,

    Let's define a few things that I think we are not communicating properly. 

    The ADAU1452 and the ADAU1466 datasheet both do not mention these opamps and do not discuss making a pseudo ground reference. Are you talking about the User guide for the EVAL-ADAU1452RevBZ? The EVAL-ADAU1466 may not be the correct user guide. 

    So what is the issue you are having? The circuits are fine and is a good example of how to interface to the codec.
