Device and method for driving digital-to-analog converter

A device for driving a switch in a digital-to-analog converter (DAC) includes first and second latches, and a logic gate. The first latch is configured to store a digital input data signal according to a clock signal, and to output a first latch signal corresponding to the stored digital input data signal. The second latch is configured to store the first latch signal output by the first latch according to a logical inverse of the clock signal, and to output a second latch signal corresponding to the stored first latch signal. The logic gate is configured to perform an OR logic operation on the first latch signal and the second latch signal, the logic gate outputting a drive signal for driving a switch in the DAC connected to a current source.
