The symbols used in this table are defined as: I = input, O = output, LI = line level input, LO = line level output, HP = output capable of driving
headphone load, MIC = input supports microphones with MIC bias and boost amplifier, SWAP = outputs can swap L/R channels (typically used
to support C/LFE or shared C/LFE function).

Connect to the I/O voltage used for the HD Audio controller signals.
Digital Supply Return (Ground).
Digital Supply Voltage 3.3 V. This is regulated down to Pin 1 to supply the internal
digital core.
CAUTION: DO NOT APPLY 5.0 V TO THESE PINS!
Analog Supply Voltage 3.3 V ONLY.

Source for Microphone Bias Circuitry.
Connect this pin to 5.0 V via a low-pass filter. When connected this way the AD1989B
is capable of providing +3.95 V as a mic bias to all of the MIC_BIAS pins.
If 5 V is not available, connect this pin to +3.3 V (AV
