Abstract
The A/D converter comprises a resistor series (30), a plurality of first comparators (1) and a plurality of second comparators (2). Resistor series (30) has a plurality of resistors(R) connected in series between two terminals to which predetermined reference voltages are applied. First comparator (1) compares a node voltage between resistors and an analog voltage signal to be compared. Second comparator (2) compares an average voltage of the two node voltages across each resistor R and the analog voltage signal. First and second comparators (1,2) are disposed alternatively.
