TPA3255: THD+N at 1W ( PEEB)

Will Chen
Prodigy 10 points
Part Number: TPA3255

Tool/software:

I have a question.
The customer is planning to use PFFB on the TPA3255.
I read the TPA3255 datasheet, which mentions a THD+N of 0.006% at 1W.
Does this refer to performance with PFFB?
If not, what is the THD+N value when PFFB is used?
Are there any other considerations or precautions when using PFFB?

    Hey Will, 

    This document contains all the precautions and related information regarding PFFB. For the THDN vs Frequency at 1W response for TPA3255, find this on page 43, Appendix E.3. The whole Appendix E covers performance results for TPA3255 using PFFB.

    Images:

    THDN below 0.01% at 1W on 4Ohm load.

    Regards,

    Ore.
