An apparatus for determining the type of accessory in a portable terminal, the apparatus comprising:
- a switching unit for controlling a power source supply time for an operation of an Analog-to-Digital Converter (ADC) via a power source independent of a power source supplying power to the ADC for other operations.
A method for determining the type of accessory in a portable terminal, the method comprising:
- controlling a power source supply time for an operation of an Analog-to-Digital Converter (ADC) via a power source independent of a power source supplying power to the ADC for other operations of the ADC.
A portable terminal comprising:
- an earphone port for connecting an accessory to the portable terminal;
- an Analog-to-Digital Converter (ADC) for determining a type of the accessory connected to the earphone port;
- and
- a switching unit for supplying power to the ADC via an independent power source not used for other operations only while the ADC is determining the type of the accessory.
A method of determining a type of an accessory attached to a portable terminal, the method comprising:
- attaching an accessory to a portable terminal;
- supplying power to an Analog-to-Digital Converter (ADC) via a power source independent of a power source used for other operations of the portable terminal;
- determining a type of the accessory via the ADC;
- and
- stopping the supply of the power to the ADC after the type of the accessory is determined.
