This invention includes a current output sensor, and a current AD conversion means which is connected to the output side of the current output sensor and has a current mirror circuit arranged on the input side of a comparator in order to directly A/D-convert an output from the current output sensor. A signal can be stably processed with a small circuit scale and low current consumption.
