Part Number: TAS5751MEVM
Other Parts Discussed in Thread: TAS5751M

Hello E2E Community

My name is Moe, and i am currently working on a audio design that involves this part "TAS5751M" audio amplifier.

My question is when i use the evaluation board along with the Pure Pathe Console, the PPC initializes the amplifier and loads a bunch of .inc files and values to the amplifier and without this procedure i cannot run the amplifier as a standalone audio amplifier.

Is there a way to make it self boot ? or do i need to store these parameters in an EEPROM and dump them to the amplifier every time? if so what parameters do i need to prepare to write to the EEPROM?

I realise there is an MSP430 Microcontroller that could be the one writing these parameters to the amplifier.

Please advise.

Thank you 


  • Hi Moe,
    As you mentioned, there are a lot of register writing operation during the initialization, but some of them are for the other parts in the board not TAS5751M AMP.
    On your board, AMP needs to be configured by MCU every time power-on. So you are right that the AMP cofiguration code has to be stored somewhere. It's very easy to generate and dump the configuration file by PPC GUI and EVM. Please refer to section 3.8 in the EVM user's guide:
