An output buffer is disclosed that includes: a buffer circuit that outputs an output signal to an output terminal based on a first input signal provided to a first input terminal and a second input signal provided to a second input terminal; and a current supply circuit that is connected in parallel to the buffer circuit, and provides an auxiliary current to the output terminal based on the first input signal and the second input signal.

Output buffer, data driver, and display device having the same

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.
