Abstract
An analog to digital converting device has a first converter nonlinearly converting an analog level into a first digital value every first sampling period, shorter than a second sampling period, with low precision, a second converter linearly converting the analog level into a second digital value every second sampling period with high precision, and a controller determining a correction equation by using the second digital value having a high precision in each second sampling period so as to renew the equation every second sampling period, and correcting the first digital values, obtained in each second sampling period, to corrected digital values according to the corresponding correction equation to output the corrected digital value as a digital value, obtained by substantially linearly converting the analog level, every first sampling period.
