PROBLEM TO BE SOLVED: To reduce an area of a semiconductor integrated circuit device comprising an A/D converter which performs conversion processing on an inputted analog signal into a digital signal by performing digital correction processing.SOLUTION: A semiconductor integrated circuit device comprises first and second A/D converters. In a first mode, a first test signal is inputted in common to the first and second A/D converters, and a first correction coefficient for the first A/D converter and a second correction coefficient for the second A/D converter are calculated. In a second mode, the first A/D converter performs first digital correction processing using the first correction coefficient, thereby performing A/D conversion processing on a first analog signal into a first digital signal, and the second A/D converter performs second digital correction processing using the second correction coefficient, thereby performing A/D conversion processing on a second analog signal into a second digital signal. |
