The purpose of the present invention is to provide an output amplifier having a rapid output arrival time and a source driver with the same. The output amplifier according to the present invention comprises: an input difference amplifying unit receiving an inversion signal and non-inversion signal of pixel data, and sensing and amplifying a difference between the inversion and non-inversion signals; a main output unit outputting a data signal outputted from the input difference amplifying unit to a display panel; at least one auxiliary output unit; and an output control unit controlling the auxiliary output unit. The output control unit drives both the main output unit and the auxiliary output unit to output the data signal in an output power increasing period when the data signal changes in magnitude, and drives only the main output unit to output the data signal to the display panel when there is no change in the magnitude of the data signal. |
