Patent ID: 7375669

Claim:
A digital/analog converter comprising: a first divided-voltage generating section which divides a reference supply voltage through the voltage distribution; a decoder section which receives a digital signal so as to output a decoded selection signal; a first divided-voltage selecting section which selects and outputs a plurality of divided voltages among the divided voltages generated from the first divided-voltage generating section on the basis of the selection signal output from the decoder section; a second divided-voltage selecting section which 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 second divided-voltage generating section which divides the plurality of divided-voltages output from the second divided-voltage selecting section and which is composed of a plurality of switches which are respectively connected to a plurality of nodes which are selected by the first divided-voltage selecting section and nodes which are adjacent to the plurality of nodes selected by the first divided-voltage selecting section; a third divided-voltage selecting section which selects a predetermined voltage among the divided-voltages output from the second divided-voltage generating section on the basis of the selection signal output from the decoder; and a voltage output section which outputs the predetermined voltage selected from the third divided-voltage selecting section.
