アナログ／デジタル変換器。[Claims for Utility Model Registration] In an analog/digital converter that converts a repeatedly given analog signal into a digital signal using successive approximation means, A. outputs a digit designation signal that controls the digits to be successively approximated by the successive approximation means. B inputs the digital signal from the successive approximation means and the digit designation signal, compares each of the signals with a preset judgment value, and determines the digit designation signal output from the data length register. and a comparison element that outputs upper and lower limit signals for control.
The successive approximation means, which receives the digit designation signal, is configured to output the previous digital signal for the higher-order digits than the designated digit, perform successive approximation for the lower-order digits, and output the digital signals. An analog/digital converter characterized by:
