Abstract
An A-D converter includes a group of resistors, a group of comparators, an encoder and an output unit. The output unit includes a correction circuit. An inverter constitutes the correction circuit. The encoder is shared in a case where the A-D converter converts an inputted analog signal to a two-bit binary code and a case where the A-D converter converts the inputted analog signal to a 4-bit binary code. The correction circuit corrects the output of the encoder when the A-D converter is to convert the inputted analog signal to the 2-bit binary code.
