An overdrive digital-to-analog converter (DAC), a source driver, and a method thereof are provided. The DAC comprises a voltage divider unit, a selection unit, a buffer unit, and a detection unit. The voltage divider unit provides a plurality of reference voltages. The detection unit outputs a regulation signal according to a comparison result between a specific reference signal corresponding to an input digital signal and an output voltage output from the buffer unit. The selection unit regulates an overdrive voltage input to the buffer unit according to the regulation signal and the input digital signal. Accordingly, the output voltage of the buffer unit is changed quickly, and the conversion speed of the DAC is improved.
