Switchable Microphone Bias. For use with Port B (Pins 21, 22).
Switchable Microphone Bias. For use with Port C (Pins 23, 24).
Switchable Microphone Bias. For use with Port E (Pins 14, 15).
Voltage Reference Filter.
Switchable Microphone Bias. For use with Port A (Pins 39, 41)
All MIC_BIAS pins are capable of:
High-Z, 0 V, 1.65 V, 3.78 V, and 3.95 V (with 5.0 V on Pin 33)
High-Z, 0 V, 1.65 V, 2.86 V, and 3.00 V (with 3.3 V on Pin 33).
CAUTION: DO NOT APPLY 3.3 V TO THIS PIN!
Filter connection for internal core voltage regulator.
This pin must be connected to filter caps: 10
μF, 1.0 μF, and 0.1 μF connected in
parallel between Pin 1 and DVSS (Pin 4).
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).
