Abstract
An analog to digital converter includes: a reference circuit adapted to generate reference voltages; differential amplifiers; normal phase circuits each of which samples a normal phase analog input signal and transfers a comparison voltage, obtained by comparison with a reference voltage generated by the reference circuit, to a first input terminal of one of the differential amplifiers when the input is differential and single-ended; and reversed phase circuits each of which samples a reversed phase analog input signal and transfers a comparison voltage, obtained by comparison with a reference voltage generated by the reference circuit, to a second input terminal of one of the differential amplifiers when the input is differential and which samples a ground level as a reference voltage of the reference circuit and supplies the reference voltage and comparison voltage to the second input terminal of the differential amplifier when the input is single-ended.
