Abstract
An analog-to-digital converter includes a D/A conversion circuit, a comparator, and a logic control module. An input signal is sampled and held to obtain a sampling signal. The D/A conversion circuit receives the sampling signal and a reference voltage signal, and an output terminal of the D/A conversion circuit outputs a first voltage signal. The output terminal of the D/A conversion circuit is coupled to at least one input terminal of the comparator. An output terminal of the comparator is coupled to an input terminal of the logic control module, and the logic control module controls the D/A conversion circuit to adjust the first voltage signal according to a comparison result of the comparator. When the number of comparisons of the comparator reaches preset digits of the D/A conversion circuit, a data output terminal of the logic control module outputs a data signal corresponding to the input signal.
