The "Mic Bias" here is really a SGTL5000 internal supply.
If it is then what's providing the bias to the mic? It's common for chips to have a micbias supply which comes out of the chip and is used by mics, this is my understanding of what this circuit is.
I did not make myself clear, but you made :) Yes, this is exactly the thing on my mind, and the circuit will look like:
STGTL5000 BOARD | MIC_IN ---+--- JACK ^ | ^ | | | | | | MIC_BAIS----+-----/ |
Isn't you helped me create this understanding? [1]
