TPA3113D2: Schematics Review

Part Number: TPA3113D2

Hello,

I've been working on a project which will be using the TPA3113D2 for two 3W, 4 Ohm speakers. As i don't have much experience with D-class amplifiers, could someone please comment on the schematics and whether it looks fine? Thank you in advance

    Hi Tomasz

       The R4 resistor should connect to PLIMIT, not GVDD. Resistor R3 and R4 supposed to divide the GVDD voltage for the PLIMIT pin.

       If you need to pass EMC, the FB at the output usually can't be saved. And if you needn't care EMC, the 1nF capacitor at the output also not necessary. 

       Other place seems fine.
