PROBLEM TO BE SOLVED: To obtain an output waveform with less distortion without increasing an operating speed of components. SOLUTION: This digital analog D/A converter is configured with a D/A converter 10, four voltage storage sections 11-1 to 11-4, 4 step function waveform generating sections 12-1 to 12-4, a voltage synthesis section 14, 2 integration processing sections 16, 18, and a timing control section 20. Each voltage storage section stores a voltage corresponding to each of 4 digital data received sequentially and each step function waveform generating section generates a step function waveform with a voltage level corresponding to the stored voltage. The voltage synthesis section 14 synthesizes the step function waveforms generated by the step function waveform generating sections and the two integration processing sections 16, 18 apply integration processing to the synthesized waveform twice to generate a consecutive analog voltage that connects received digital data.
