An integrated circuit device comprises a first external reference voltage pin and a second external reference voltage pin. External reference voltages are applied to these pins to provide the supply voltage of a D/A converter and the output of the D/A converter is fed into a gate of a driving MOSFET via an inverting circuit and a logic gate. In one embodiment, resistors in a first resistor group have one end connected to first external reference voltage pins and resistors in a second resistor group have one end connected to second external reference voltage pins. The other ends of the first and second resistor groups are connected in common and the potential at the common connection point is applied via an inverting circuit and a gate circuit to a gate of a MOSFET.
