Abstract
An A/D converter includes: an A/D converter circuit that causes a dissipation current (I) having dependence on an input voltage (V); and a counteracting current generation circuit controlled based on an output digital value (D) provided from the A/D converter circuit to generate a counteracting current (I) that is a dissipation current for reducing the dependence of the dissipation current (I) on the input voltage.
