Patent attributes
The present invention relates to a digital/analog converter. The digital/analog converter includes a divided-voltage generating section that divides a reference supply voltage through the voltage distribution; a decoder section that receives a digital signal so as to output a decoded selection signal; a first divided-voltage selecting section that selects and outputs a plurality of divided voltages among the divided-voltages generated from the divided-voltage generating section on the basis of the selection signal output from the decoder section; a second divided-voltage selecting section that selects and outputs a plurality of divided-voltages among the divided-voltages output from the first divided-voltage selecting section on the basis of the selection signal output from the decoder section; a divided-voltage storing section that charges and discharges the plurality of divided-voltages output from the second divided-voltage selecting section; a third divided-voltage selecting section that selects a predetermined voltage among the divided-voltages discharged from the divided-voltages storing section on the basis of the selection signal output from the decoder; and a voltage output section that outputs the predetermined voltage selected from the third divided-voltage selecting section.
