Digital-to-analog converting circuit, electrooptical device, and electronic apparatus

An electrooptical device provided with a plurality of scanning lines, a plurality of data lines, electrooptical elements respectively disposed at intersections of the respective scanning lines and the respective data lines, and a data line drive circuit that supplies an analog current to the respective data lines, wherein:

• the data line drive circuit includes:
• a first digital-analog converting circuit portion that inputs first digital data and converts the first digital data to a first analog current;
• and
• a second digital-analog converting circuit portion that inputs second digital data, corrects the first analog current outputting from the first digital-analog converting circuit portion based on the second digital data, and outputs it as a second analog current;
• and
• the first digital-analog converting circuit portion includes:
• a plurality of drive transistors that are driven based on a current that becomes a reference;
• and
• a plurality of switching transistors that are series-connected to the plurality of drive transistors, wherein:
• based on the first digital data, the plurality of switching transistors are selected, currents output from the drive transistors that correspond to the selected switching transistors, respectively, are added and output as the first analog current to the second digital-analog converting circuit portion.
