Hello,
Now, I try to make some ultra low powered hands-free device.
So, I need an very efficient audio amplifier for headphone.
But, Ti only provide Class AB or G headphone amplifier.
At this point, I have some questions.
I know that Class D, switching amplifier, has superb efficiency than linear amplifiers.
However, your company does not manufacture Class D for arbitrary headphones.
Surely, EMI problem will occur, but I think EMI problem can be solved by enough off-chip low pass filter.
I guess there are some other reasons I pass over.
Are there any critical issues make Class D topology unsuitable for headphone amplifier?
Thanks and regards
J.H.Lee
