In a data driving device, a display apparatus having the data driving device and a method of driving the data driving device, an input circuitry receives an image data signal in a digital form from an exterior, and a converter converts the image data signal from the input circuitry into a data voltage in an analog form. An output buffer amplifies the data voltage from the converter. Based on the data voltage amplified by the output buffer, a voltage divider outputs two or more pixel voltages having different voltage levels from each other. Thus, a size of the output buffer and the converter may be reduced while increasing the number of pixel voltages output from the data driving device.
