Abstract
A magneto-sensitive integrated circuit which amplifies a magneto-sensitive output voltage of a Hall element by an amplifier to generate an amplified voltage, converts an output voltage of the amplifier into a digital signal by an A/D converter; and generates a reference voltage of magnitude corresponding to an indicated value. The amplifier includes a voltage superposition element which superposes a DC voltage corresponding to the reference voltage on the amplified voltage to generate the output voltage of the amplifier.
