Hi TI Teams,

Can u help to check the schematic of TPA3138D2? The schematic is as below:

TPA3138D2 schematic.pdf

And we also have one question, does the PIN2 (shutdown) can be pulled up or down all the time?

Thanks,

Kind Regards

    Hi Lumina,

    Please make sure LB800~LB804 are magnetic beads rather than 0Ω resistance. Besides this, I don't find other question.

    The SD/FAULT input pin should be held high during normal operation when the amplifier is in use. Pulling SD/FAULT low causes the outputs to mute and the amplifier to enter a low-current state. Never leave SD/FAULT unconnected, because the amplifier operation would be unpredictable. 

    Regards,
