The analog switch compares the voltage level on the analog input terminal side and the voltage level on the analog output terminal side of the analog switch, and controls the control input of the analog switch so that the analog switch becomes conductive or non-conductive depending on the magnitude relationship. A control comparator is connected to the analog output side of the analog switch, and accumulates the signal voltage input through the analog switch when the analog switch is conductive, and continues to hold the accumulated signal voltage when the analog switch is non-conductive. A level detector comprising a memory circuit and an output buffer that outputs a voltage held by the memory circuit.
