TPA2000D1-Q1: Issue with audio amplifier

Part Number: TPA2000D1-Q1

Hi there,

I am using TPA2000D1TPWRG4Q1 along with 6PAIC3109TRHBRQ1, I could not get sound at the audio amplifier output, I have connected speaker at CODEC output it, Sound is coming. but, at the amplifier output it is not coming. could any one solve my issue, attached the schematic for reference.

Thank you.

Uttej Ravuri.

  • Hi Uttej,

    Do you have captures of the signals around the device? I mean input signals at INP/INN, output signals at OUTP/OUTN before and after the output filter. Perhaps also the Shutdown signal would be good to see as well.

    I think the first thing to look at is the output, this is a Class-D amplifier so there should be a PWM at the output at least if the device is operating.
