Abstract: <P>PROBLEM TO BE SOLVED: To achieve a highly precise A/D conversion while excluding the influence of power supply noise.  <P>SOLUTION: In the A/D converter 107, if an A/D conversion initiation request 106 occurs with respect to a potential to be supplied to an analog input terminal 102 while converting operation is carried out for converting a potential supplied to an analog input terminal 104 into a digital value 113, an SH circuit 115 is caused to carry out sampling operation for sampling the potential to be supplied to the analog input terminal 102 and hold operation for holding that potential as an analog value.
