Summary:PROBLEM TO BE SOLVED: To provide a converter capable of obtaining a stable output even when the resistance of the resistor of a resistor column is changed by a temperature or the like in a potential difference digital/analog converter provided with a resistor array. SOLUTION: Taps are made at two points symmetrical to the position of the average resistor of the resistor array of this potential difference digital/ analog converter, then the output of the two taps are averaged to obtain the output of the converter, thus a stable converter output insensitive to the change of the resistance of the resistor of the resistor column is obtained.
