摘要：An AD converter having a series resistor arranged to generate at each ofconnection points a reference voltage to convert an analog value to a digital value, andsemiconductor switches each constituted by a parallel combination of a PMOSFET and anNMOSFET and disposed one for each of the connection points, the AD converter, while
applying a first voltage to a first gate electrode of the PMOSFET to bring the PMOSFETinto conduction and a second voltage higher than the first voltage to a second gateelectrode of the NMOSFET to bring the NMOSFET into conduction, generating the digitalvalue on the basis of results of comparing the analog value with the reference voltagesoutput from the semiconductor switches, comprises a control circuit operable at leasteither to step down the first voltage applied to the first gate electrode or to step up thesecond voltage applied to the second gate electrode.
