Abstract
This invention is a D/A converter including a preset current source, first and second differential switches for selectively deriving an output current of the preset current source in response to complementary signals supplied to control electrodes thereof, and an imaginary short circuit for connecting output portions of current paths of the switches to each other. Variation in the voltage at the time of switching operation of the differential switch can be suppressed by use of the imaginary short circuit with the above construction, thus making it possible to enhance the operation speed.
