Hi MJ,

The schematic you shared looks good. I see no problems with it.

My one point is that for reducing EMI the customer may consider using a ferrite bead or small inductance in place of R362/363. this will also suppress EMI from the outputs, and it will not dissipate as much power as pure resistance.

Here is an App note I found that discusses LC filters for Class-D amplifiers https://www.ti.com.cn/cn/lit/an/sloa119b/sloa119b.pdf?ts=1639600667312&ref_url=https%253A%252F%252Fwww.google.com%252F

this app note is referencing an Audio amplifier but the concepts are the same
