Function
Negative power supply pin; this pin is connected to the system ground
MIC output pin with open drain output type; When the headset is asserted, then MIC is pulled
up to the MIC bias voltage with a pull-up resistor. When the headset is not asserted, then MIC
is pulled low.
Ground detection pin
Left channel detection pin
Positive Power Supply Pin, which pin is connected with system power supply. A minimum
0.1µF decoupling capacitor is recommended as close as possible to this VCC pin.
OUT is a logic output that indicates whether the headset has been properly connected. OUT
will be logic low only when G_detect and L_detect are low.
