Other Parts Discussed in Thread: TPA3116D2EVM

TPA3116D2EVM_Rev C.  Line 5 of Rev C History says "R22 (100K) added and connected U1-12 (mute net) and GVDD net. Schematics shows R22 connected to PVCC, not GVDD. Which is correct,  please?

    Bruce,

    Nice catch!!! The schematic is correct, the notes are incorrect. We will get this fixed.

    GVDD is sensitive to current drawn from it, so you don't want to hang more stuff than needed from it.

    Thanks Don. I have an application question that will require you look at my schematic. Do you do that sort of thing? Not asking for you to design anything,  just verify my plan is potentially "sound" before I proceed with hacking up my EVM board. Can I send the drawing to you or is there a way to post it here? Please tell me if this is beyond the scope of this forum and I will respect that.

    Thanks

    Hi, Bruce. You can post your schematic here, and I can take a look at it to see that it's sound. I am catching up from being on vacation, so it may not be for a while, but I can still review it. Please expect a delay.

    To post your schematic, open up the reply window in E2E. On the same row as the B, I, and U settings, you'll see a green square icon with a small plus in its lower right corner. To the right of that green square is a paperclip that's surprisingly stout. Click on that paperclip icon, and you'll see a dialog for attaching files, such as a PDF of your schematic.

    Best Regards,
    Matt
