ABSTRACT:
An analog-to-digital conversion circuit includes a plurality of comparators and an averaging circuit. The averaging circuit is configured so that a length of a metal routing connected between output terminals of two comparators arranged on a leftmost side from among the plurality of comparators or a length of a metal routing connected between output terminals of two comparators arranged on a rightmost side from among the plurality of comparators is less than a length of a metal routing connected between output terminals of two comparators to which reference voltages having levels that are closest in magnitude are input.
