DIGITAL-ANALOG CONVERTER

PROBLEM TO BE SOLVED: To solve a problem wherein an existing digital-analog converter cannot improve conversion accuracy.SOLUTION: A digital-analog converter includes: a higher digital-analog converter DA1 for outputting a first analog voltage VO1 and a second analog voltage VO2 corresponding to a value of higher m bits of a digital input value; a lower digital-analog converter DA2 for dividing a voltage difference between a voltage VR1 at a lower voltage node ND1 and a voltage VR2 at a higher voltage node ND2 in accordance with a value of lower n bits of the digital input value to output an analog output voltage VOUT; a first capacitor C1 connected to the lower voltage node ND1; and a second capacitor C2 connected to the higher voltage node ND2. The higher digital-analog converter DA1 outputs the first and second analog voltages VO1, VO2 exclusively to the lower digital-analog converter DA2.
