TLV320AIC3254: TLV320AIC3254, latest documentation errors?

Part Number: TLV320AIC3254

Hello,

Can you confirm these errors/misprints in the TLV320AIC3254 Application Reference Guide, SLAA408A:

1) page 129, register page 0, register 13 - D3 should be "Right Channel DAC reconstruction filter's negative terminal is/is not routed to HPR"?  I don't see a possible routing from the positive terminal.pag

2) page 139, register page 1, register 54 - all bit headings should read "negative terminal selection", to match the register name/function?

I've assumed these are both the case, but am having problems with configuration/operation, and just wanted to make sure.

Regards,

Robert

P.S. Is there a newer version of this app note? I couldn't find one.

    Hi, Robert,

    1) The app note is correct. It must be "Right Channel DAC reconstruction filter's positive terminal is/is not not routed to HPR". You may get more details about this in the AIC3254 CS software:

    2) Thank you for this observation. You are correct. I will notify this in order to avoid confusions in the future.

    The SLAA408A is the most recent version of this app note.

    Please let me know if you have additional questions or comments.

    Best regards,
    Luis Fernando Rodríguez S.

    Luis,

    Thanks. For 1) I had been referencing an incorrect diagram of the codec, with the right DAC polarities swapped. It now makes sense.
