TAS5825M: Converting amp parameters to registers in custom application

Part Number: TAS5825M
Other Parts Discussed in Thread: TAS5782M, , TAS5782MEVM

Dear TI team,

PPS3 allows me to generate and upload parameter specific register values to amp via EVM board.

What design framework and/or toolset is necessary and provided by TI to build the solution that (without a need to have EVM board):

a) allows user-defined amp configuration parameter values to be uploaded to manufactured board with TAS5825 amp, including gain, input selection, mute and some or all bicubic filter transform settings used for EQ adjustment;

b) some of those parameter values to be locked as factory presets

Same question is about TAS5782 for which I have already manufactured a prototype board with STM32 microcontroller.

Best regards,

Jānis Irbe

  • Janis,

    The only official software for TAS5825M and TAS5782M is the PPC3 (PurePath Path Console 3). If you want to generate headers files for system integration, you do need to have the TAS5825MEVM or TAS5782MEVM connected.

    See my other comments on your questions below.
    a) allows user-defined amp configuration parameter values to be uploaded to manufactured board with TAS5825 amp, including gain, input selection, mute and some or all bicubic filter transform settings used for EQ adjustment;
    [Andy] As I metioned above, the only tool available is PPC3. After your tuning is done, you can generate header files which contain all your seetings, including the gain setting, EQ coefficients and other settings.

    b) some of those parameter values to be locked as factory presets
    [Andy] All the settings have to be programmed to TAS5825M or TAS5782M via i2c after the device is powered on since TAS5825M or TAS5782M has no internal flash memory.
