PROBLEM TO BE SOLVED: To provide a digital/analog converter that can reduce a noise caused when received digital data are switched. SOLUTION: The digital/analog converter is provided with resistive elements (R1-Rn+1) connected in series, with differential circuits (M11, M12 and I1, M21, M22 and I2,..., Mn1, Mn2 and In) that are placed corresponding to each of connecting points (T1-Tn) of the resistive elements and each of which outputs a voltage from the connecting point by its built-in current source being activated by a decoder (10) and with the decoder (10) that activates any current source in the differential circuits in response to external digital data.
