Abstract:
An AD converting device includes a resistance-voltage conversion circuit which changes a first integrated voltage in proportion to a product of a varied resistance of a variable resistance and an electrical current applied to the variable resistance and changes a second integrated voltage and a reference voltage in proportion to a product of a total resistance of the variable resistance and the electrical current.
