Claim 0:
1. An A/D converter configured to perform an A/D conversion on an input signal to output ADC result data, the A/D converter comprising:
a D/A conversion circuit configured to perform a D/A conversion on a DAC input digital value to output a DAC output signal;
a difference output circuit configured to output difference signals based on a difference between the input signal and the DAC output signal;
an A/D conversion circuit configured to perform an A/D conversion on the difference signals to output an ADC output digital value; and
a control circuit configured to output the DAC input digital value based on the ADC output digital value, wherein
the control circuit is configured to
output a first DAC input digital value and a second DAC input digital value different from the first DAC input digital value as the DAC input digital value, and
obtain the ADC result data based on a first ADC output digital value as the ADC output digital value obtained in accordance with the first DAC input digital value, a second ADC output digital value as the ADC output digital value obtained in accordance with the second DAC input digital value, and the DAC input digital value.
