摘要：PROBLEM TO BE SOLVED: To suppress the situation that an abnormal digital signal is outputted, by correctly converting an analog signal into a digital signal even if a level of the analog signal can not be detected. SOLUTION: The AD converting circuit includes at least any one of a first level fixing circuit for converting an analog signal into a digital signal of a first fixed level if a level of this analog signal is lower than a level of a reference signal, and a second level fixing circuit for converting an analog signal into a digital signal of a second fixed level if a level of this analog signal is higher than the level of the reference signal.
