The MC13783 provides a headset detection scheme based on the sleeve detection, left channel impedance
detection and microphone bias detection which is valid for headsets with or without phantom ground
connection. It is compatible with mono headsets where the left channel is connected to ground.

Line Output Amplifier Arxout
The Arxout amplifier combination is a low power stereo amplifier. It can provide the stereo signal to for
instance an accessory connector. The same output of the selector block is used for the internal connection
to the USB transceiver for CEA-936-A Carkit support.
