ことを特徴とするアナログ・ディジタル変換器。The reference voltage is used as a unit voltage, and the difference between the six-input analog voltage and the subtracted voltage that increases stepwise is cut off, and when the difference voltage becomes smaller than the unit voltage, the difference voltage is appropriately amplified and then converted into a digital signal. While obtaining the voltage value, a digital value corresponding to the subtracted voltage is obtained to obtain an upper voltage value, and the upper voltage value and the lower voltage value are combined to obtain a digital conversion value of the input analog voltage.
