A digital-to-analog converter of a data driver and a converting method thereof, in which information corresponding to a lower bit is converted into an analog signal through control of current transmission paths and control of a transconductance ratio. Input data corresponding to a lower bit is converted into an analog signal through control of current transmission paths and control of a transconductance ratio between a delta current generation section and an output buffer amplifier. As a consequence, not only the area of a data driver can be significantly reduced, but also the delta current generation section can be realized even without using a common node feedback circuit, whereby an additional increase in area is not caused.
