Analog-to-digital converter and threshold-value correcting method
An analog-to-digital converter includes a track-and-hold circuit, a constant-voltage source, a threshold voltage selection circuit, a first comparator to a seventh comparator, an encoder, and a reference voltage output circuit. In a correction mode where the offsets of the first to seventh comparators are to be corrected, a track-and-hold circuit shuts off the input of an analog voltage to the first to seventh comparators by turning off the track-hold switch.
