PROBLEM TO BE SOLVED: To provide a digital analog conversion circuit capable of reducing the variation of settling time due to correspondence of a differential pair and the voltage.SOLUTION: A digital analog conversion circuit 1020 includes a selector unit 102D for selecting a plurality of nodes from a voltage-dividing circuit according to the high-order side bit information of a digital signal and outputting a voltage, and a differential amplification unit 102F including a plurality of differential pairs to which the output voltage from the selector unit is inputted. Correspondence of the output voltage from the selector unit and the input of each differential pair of the differential amplification unit is controlled according to the bit information on the low-order side of the digital signal, and a voltage according to the digital signal is outputted. When outputting a voltage according to the digital signal, the correspondence of the output voltage from the selector unit and the input of each differential pair of the differential amplification unit is set to a correspondence of short settling time, and then the correspondence of the output voltage from the selector unit and the input of each differential pair of the differential amplification unit is controlled according to the bit information on the low-order side of the input digital signal.SELECTED DRAWING: Figure 4
