Other Parts Discussed in Thread: TPA0211, TPA0211EVM

TPA0211 datasheet written in "Stereo Single End (SE)".

※Page19

But I think that TPA0211 is Mono SE speaker AMP because of TPA0211 is single input.

Which is correct (Mono or Stereo)?

Or, is use case of SE mode premise two device combination?

※For example, TPA0211EVM User's Guide P16.

 

Best regards,

Satoshi

    Hi Satoshi-san

    The page 19 of the datasheet refers to the output modes you can choose between BTL output(stereo) to connect a speaker, SE output(mono) to connect a headphone or both options, this behavior is very useful for some applications.
    The page 16 of the user's guide refers to a stereo input and single ended output.

    Please let me know your opinion.

    Best regards
