Abstract
Disclosed are a digital-analog converter and a camera module having the same. The digital-analog converter includes a plurality of decoders for receiving bits of a digital input signal by dividing the bits in a predetermined bit unit except for lower bits of the digital input signal, and decoding the bits into thermometer code signals, a delay unit for delaying output of the lower bits of the digital input signal, a latch unit for synchronizing output signals of the decoders with an output signal of the delay unit, and a current source for converting a digital signal output from the latch unit into an analog signal.
