Abstract
An audio jack detection circuit includes an impedance detecting circuit configured to generate a detection signal corresponding to an impedance between a ground pin and a ground detection pin, which are in contact with a ground terminal of an audio jack socket, and a controller configured to determine a state of the audio jack socket based on the detection signal. A detection range of the impedance detected by the impedance detector may be controlled by varying a resistance of a pull-up resistor connected to the ground detection pin.
