ABSTRACT:
A digital-to-analog conversion circuit of charge distribution type includes a plurality of capacitors having respective capacitances that increase in a sequential order, one end of the capacitors being commonly connected electrically. The circuit also includes a plurality of analog switches each for electrically connecting a reference potential corresponding to a digital signal inputted from outside to the other end of the corresponding capacitor. These analog switches have respective driving capacities that increase in a sequential order.
