Abstract: An analog-digital converter according to the present invention includes an input polarity switching unit, an integrator that integrates an input signal, an integrator output adjusting circuit that adjusts an output voltage of the integrator, a window comparator, and a controller that controls the input polarity switching unit, the integrator output adjusting circuit, and the window comparator, and generates a digital signal. When the output voltage of the integrator reaches a first reference voltage, the controller resets reference voltage of a high-voltage side comparator to a second reference voltage. Further, when the output voltage of the integrator reaches a third reference voltage, the controller resets reference voltage of a low-voltage side comparator to a fourth reference voltage. According to the analog-digital converter of the present invention, it is possible to prevent device breakdown and occurrence of through current due to fluctuation of the output voltage of the integrator.

Abstract: There is provided an analog-to-digital converter capable of performing analog-to-digital conversion with good accuracy. The analog-to-digital converter in accordance with the present invention includes a dither generation circuit 11 which generates dither; an input polarity switching unit 1 which switches a polarity of an input signal; an integrator 2; an integrator output regulator circuit 5 which regulates an output voltage of the integrator 2; a window comparator 3; a control circuit 4 which uses the comparison result of the window comparator 3 to control the input polarity switching unit 1, the integrator output regulator circuit 5, and the window comparator 3 as well as to generate a digital signal. The dither generation circuit 11 generates dither in such a manner that a cycle in which the digital signal is read is an integral multiple of a dither cycle. Further, the dither generation circuit 11 generates dither in such a manner that the number of times the count value is generated in the first half of one cycle of the dither is different from the number of times the count value is generated in the second half cycle thereof.
