Abstract
A digital/analog conversion circuit including plurality of digital/analog converters, a signal synthesizing circuit and a data converting section. The digital/analog converters convert their digital data to corresponding analog signals. The signal synthesizing circuit additively synthesizes respective outputs of the digital/analog converters in a predetermined synthesizing ratio. The data coverting section is provided at an input side of at least one of the digital/analog converters to convert input digital data to data for correcting errors emerging from the output of the signal synthesizing means due to errors among the digital/analog converters and to supply the correcting data to the following digital/analog converter.
