Dear TI team,
Are MOUTP/MOUTN biased by TPA6166A2?
As per our observation, it seems not biased.
I am wondering if I should insert capacitor between our audio codec mic input and TPA6166A2 MOUTP/N outout.
If not biased by TPA6166A2, I think I should bias MOUTP/MOUTN externally so that audio codec can receive signal correctly.
If biased by TPA6166A2, capacitor should be inserted between our audio codec mic input and TPA6166A2 MOUTP/N outout. so that bias from Audio Codec might be at different level from bias from TPA6166A2.
BR,
Matsuda
