ABSTRACT:
A converter10selects desired unit current cells from unit current cells16, 18, 20, 22in accordance with an input code102, and supplies currents from the selected cells to a load resistor24to generate an analog voltage Vdac. By supplying the constant current comprised of the currents from the selected cells and currents from non-selected cells to an offset adjuster circuit26including an adjusting resister28to generate an offset voltage Vos, the converter10can output a voltage Vout which is the sum of the analog voltage Vdac and the offset voltage Vos.
