TAS5822M: TAS5822M no sound

Part Number: TAS5822M

Hi team,

Regarding the control of tas5822 PDN, after pulling PDN low and then high, the customer reset the initial table settings.

But there is still no sound.

The customer followed the note in datasheet 7.4.7 about this problem, and then restarted according to the sequence of 7.5.3.1. , it still doesn’t work,

The customer would like to know, if point 4 of 7.5.3.1 necessary?

Is there anything the customer should adjust and notes?

The customer's initial table did the following actions.

We don’t know if there is something wrong. Please help me to take a look, thank you!

BRs,

Jamie

  • hi Jamie

    how you config the initial file, we have a ppc3 sw which can generated the initial file.

    it seems like you configuration data is so less.

    point4 is necessary. we need i2s clk to let dsp work. then the register data can be configured into chip.

    tks
