ABSTRACT:
A simple DA converter circuit which reads in digital voltage value data and outputs analog current value data is provided. The DA converter circuit according to the invention can be applied, for example, to a data driver circuit of an AM-OLED display device. The DA converter circuit comprises a current output circuit comprising a plurality of drive transistors. Gate electrodes of the transistors are electrically connected to each other, and a switch is provided between the gate electrode and drain electrode of each drive transistor.
