A D/A converter is provided which is capable of avoiding an increase in occupied areas of the D/A converter on a board and of obtaining an output characteristic being excellent in linearity, which enables achievement of the D/A converter having a small integral-linearity error (INL) and a small differential-linearity error (DNL). The reference current composite blocks are cascaded between current controlling device groups and an output switch. At least one out of reference current composite blocks divides composite reference current amounts based on a predetermined weight and outputs them.
