TAS5825M: Default configuration

Markus Krautter

Part Number: TAS5825M

Hello TI service team,

I build an amplifier board with the TAS5825M in BTL mode. Now I was wondering if there is any basic program loaded after startup.

Are there default values for the internal registers? Or is there any default Process flow loaded? If that's not the case, without an EEPROM, a master mcu for init tasks is always needed?

Thanks for any suggestions.

Greets, Markus.

    Hi Markus,

    Do you have a TAS1020 on your board? If you have, please use PPC3 GUI for the basic program.

    If you do not have it, please:

    1. Before you write the basic programme, please make sure I2S is on;
    2. Then you can refer to page 43 the datasheet for Register Maps;
    3. For BTL, you can start you device with:
      1. w 98 00 00
      2. w 98  7f 00   //see page 40 of datasheet of "DSP Memory Book, Page and BQ update"
      3. w 98 03 03
      4. w 98 78 80

    For the long term, I would suggest you install PPC3 GUI to get "complete" code.

    Regards,

    Alix Wan.
