One thing need to be paid attention to is that the BST caps we recommend are 33nF rather than 47nF.

The other parts are okay.

Hi Wei Qiu,

Thanks for the feedback. What is the impedance of the 10W speakers that PA supports?

Regards,

Naveen

The impedance we recommend is shown below:

If you want to use smaller impedance of speakers, you need to keep the output current less than the OC value and leave enough margin, we strongly recommend to configure it according to the recommended value of the datasheet.
