Abstract
A digital-to-analog converter ('DAC') converts digital image data into analog image signals. The DAC includes a stage outputting different voltages to a first output terminal and a second output terminal based on a voltage supplied to a first input terminal, a voltage supplied to a second input terminal, and a first input bit. The stage includes a switch circuit including switches that are alternately turned on by a control signal, and outputting an intermediate output voltage to a third output terminal based on a first input voltage supplied to the first input terminal and a second input voltage supplied to the second input terminal, and a selector outputting one of the first input voltage and the second input voltage, and the intermediate output voltage.
