ABSTRACT:
A current output device of a data driving apparatus sequentially applying data signals to data lines. The data signals correspond to analog converted output currents and the current output device includes a switch controlling supply of the analog output currents according to a first control signal, a master current sample/hold circuit sampling or holding the analog output currents according to a second control signal, a slave current sample/hold circuit holding or sampling the analog output currents according to a third control signal, and a multiplexer selecting an output current held in the master current sample/hold circuit or the slave current sample/hold circuit according to the fourth control signal and applying the selected output current to a corresponding data line.
