Abstract
A kickback current is suppressed so as not to generate a deviation in a signal that outputs a comparison result. A comparator includes a first input terminal and a second input terminal to which a first differential input signal pair is input, a third input terminal and a fourth input terminal to which a second differential input signal pair is input, a first comparison circuit that outputs a signal corresponding to a difference signal of the first differential input signal pair generated by connecting the first input terminal to a positive side and connecting the second input terminal to a negative side and a difference signal of the second differential input signal pair generated by connecting the third input terminal to a positive side and connecting the fourth input terminal to a negative side, and a second comparison circuit that outputs a signal corresponding to a difference signal of the first differential input signal pair generated by connecting the first input terminal to a negative side and connecting the second input terminal to a positive side, and a difference signal of the second differential input signal pair generated by connecting the third input terminal to a positive side and connecting the fourth input terminal to a negative side.
