Abstract
A semiconductor integrated circuit apparatus has reference potential supplying pads to which reference potentials VREFH and VREFL are respectively supplied from an outside, a string resistor STRG with a plurality of taps, and reference potential wires formed between the pads and opposite ends of the string resistor STRG, respectively, where a resistance of a resistive element at one end of the string resistor is set in advance at a value lower than a resistance of resistive elements at an intermediate portion by a value corresponding to a wiring resistance parasitic on a reference potential wire, and another resistance of another resistive element at the other end of the string resistor is set in advance at a value lower than the resistance of the resistive elements at the intermediate portion by a value corresponding to another wiring resistance parasitic on another reference potential wire.
