Abstract
A digital-to-analog converter including includes a decoder which receives m (where m>=4 holds) reference voltages having voltage values that differ from one another, and selects and outputs n (where n>=3 holds) identical or different voltages from among the m reference voltages based upon a digital signal; and an amplifying circuit that outputs a voltage, which is obtained by taking the weighted mean of the selected n voltages at a ratio of 2n−1:2n−2: . . . :20, from an output terminal.
