DEM-PCM2912AEVM: User guide not found

Part Number: DEM-PCM2912AEVM
Other Parts Discussed in Thread: PCM2912A

Hello,

I'm searching the user's guide about the DEM-PCM2912AEVM, I have found the document on this link DEM-PCM2912AEVM Evaluation board | TI.com but I don't have the same Eval Board (see the picture in attachement at this message). Where I can found the user guide ?

My second question is the following : with the PCM2912A component, is it possible to connect a DAC and speakers ? What's type of DAC I have need to have a correct sound level and not distorsion? It's for a laptop application.

Thank You

Hi,

This EVM was updated due to some components obsolescence, here is the updated schematic.

AMPS149A(001)_Sch.PDF

You can still use the SBAU141 user guide.

This is an audio USB converter and has DAC inside already, not possible to connect an external DAC.

Regards,

Peter

Thank you for your answer.

I made a mistake, I don't want connect a DAC but I want to connect an amplifier. Is it possible to have a good sound and no distorsion ? What's are the solutions ?

Hi,

If you want to connect an external amp, out of band noise is something to consider.

See this apps. note for common audio noise.
