ABSTRACT:
An analog/digital converter circuit including a plurality of reference resistance elements dividing a voltage between two reference potentials to provide a plurality of reference voltages; a plurality of switching blocks which are activated by an upper data conversion output signal in units of rows and compare the respective reference voltages with an input signal to be converted to provide a differential output; an upper data encoder which compares the reference voltage supplied to a switching block positioned at a specific position of the switching block matrix with the input signal to provide a plurality of conversion codes of the upper significant bits; a lower data comparator circuit having first and second comparators with weights N.
