Abstract
A hybrid digital to analog converter (DAC) includes a first digital to analog converting unit (DACU) and a second DAC unit. The first DAC unit provides an analog voltage corresponding to Q-bit upper data of P-bit gray data, in response to a plurality of gamma voltages, where P is a natural number equal to or greater than 10 and Q is a natural number less than 10. The second DAC unit provides an analog current having a magnitude according to each bit level of R-bit lower data of the P-bit gray data, based on a rated current generated from a reference voltage, where R is a natural number corresponding to P-Q.
