Part Number: PCM4104

Hi ti team,

A new project is using the PCM4104. Please help check the attached schematic and the three-channel output filtering circuit of the PCM4104 for any issues. Thanks!

    Hello, overall it looks ok to me. 

    The only comment that I have is  VOUT of each channel is differential and thus I would keep the symmetry on them all the way . Seems you have a resistor and a capacitor to ground only on positive terminal of the 3 channels you are using. It is ok to leave the unused VOUT4 float. 

    You can refer to the following schematics as a reference. 

    Kind Regards,
