Abstract
A semiconductor integrated circuit includes a plurality of comparators for comparing an analog input with reference voltage or voltages, holding means for holding a digital value, and control means for controlling the outputs of the plurality of comparators by a control signal responsive to the digital value to output the multiplication result of the output values of the plurality of comparators and the digital value. Thus, the integrated circuit can construct a circuit having functions of an A/D converter and a multiplier on one chip.
