Hello,

Please see my review notes below:

- Pin 25 is mislabeled but routed correctly. It should be OUTPL.
- I just want to confirm that SD which is an active low pin has have a pull down. If this is the desired configuration for the host there is no issue.

Other than those two points the schematic looks good.

Regards,
Sydney Northcutt

Hi Sydney

Thanks for your support.

The AMP input part has been changed and I request a review again.

Hi David,

For differential input in PBTL mode, you must use the RINN and RINP pins. The left channel inputs are not used in PBTL mode.

The other previous recommendations have been taken care of.
