The application relates to the technical field of audio interfaces, in particular to an audio output and power
amplifier output
integrated circuit and device, which comprises a
machine jack detection module, a power
amplifier triggering module and an audio output module; the input end of the
machine jack detection module is connected with a
machine jack, and is used for determining a power
amplifier on-off
control signal according to the section type of the machine jack; the machine jack detection module is connected with the power amplifier triggering module, and is used for controlling the on-off of a power amplifier device in the power amplifier triggering module according to the power amplifier on-off
control signal; the machine jack is connected with the power amplifier triggering module, and is used for grounding to form a loop, so as to determine a corresponding output mode adjustment
signal according to the power amplifier on-off
control signal; the output end of the power amplifier triggering module is connected with a
loudspeaker output unit and a headphone output unit, and is used for determining the on-off of the
loudspeaker output unit and the headphone output unit according to the output mode adjustment
signal. The application can realize the function of adding power amplifier output on the common audio output machine jack, so as to reduce the beneficial effect of the interface use requirement.
