Data Sheet Confidential - Detail ed Descri ption- Audio Functi ons

The ground cancellation can be disabled by shorting the 20

Ω resistor setting bit gnd_sw to ‘1’. This bit should be set if

e.g. a headphone instead of the car amplifier is connected to the output jack.

Note: A similar cicuit can be used for the headphone amplifier.
