摘要： A first voltage dividing circuit is connected between a power feeding line to feed power from an external power supply to an internal circuit, and a fixed potential to divide a voltage of the power feeding line. A first comparator compares a divided voltage, which has been divided by the first voltage dividing circuit, with a reference voltage, and outputs a signal to turn off a power switch inserted into the power feeding line when the divided voltage exceeds the reference voltage. A first transistor is connected between a first node where the divided voltage, which has been divided by the first voltage dividing circuit, is generated, and the fixed potential, and is turned on when the voltage of the first node exceeds a set voltage.

摘要： A first amplifier circuit samples and holds an input analog signal and outputs the same to a subtracting circuit. An AD converter circuit converts the input analog signal into a digital value so as to retrieve a predetermined number of bits. A DA converter circuit converts the digital value derived from conversion by the AD converter circuit into an analog value. A subtracter circuit subtracts an output analog signal from the DA converter circuit from the analog signal input via a first switch or the first amplifier circuit. A second amplifier circuit amplifies an output analog signal from the subtracter circuit by a gain of 2 and outputs the amplified signal. An input switching circuit controls the order of inputs, i.e. the input analog signal and a reference voltage, to voltage comparison elements constituting the Ad converter circuit.
