<P>PROBLEM TO BE SOLVED: To provide a digital-analog converting circuit capable of highly accurately converting an analog signal corresponding to digital data even if each transistor has variations, a digital-analog converting circuit capable of improving display quantity by suppressing variations in data signals to be outputted from a data line driving circuit, an electrooptic apparatus, and an electronic apparatus. <P>SOLUTION: A reference current generating circuit SK is configured by a transistor Qref for constant current and first and second reference current generating transistors Qv1, Qv2. The transistors Qv1, Qv2 are controlled according to variations in characteristic of first and second data line driving circuits, thereby finely dividing and adjusting the current value of a reference current Iref and the voltage value of a reference voltage Vref. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
