TPA3116D2: TPA3116D2 POP

Part Number: TPA3116D2


Tool/software:

Hello,

My input is a continuous sine signal, and I only control the MUTE pin to loop and achieve playback for about 300ms and mute for about 30ms. Discovered a POP sound issue with the speaker. The circuit diagram and measurement waveform are as follows: How can we solve this problem? thank you

  • hi

    can you explain what is the meaning of yellow and blue line?

    are they different channel's output?

    about the pop issue, can you check the waveform before the LC filter, let us check whether it is because of the mismatch between outp and outn?

    tks
