Abstract

PURPOSE:To execute the equivalent conversion of high resolution by obtaining the signal of an (n+1)-th bit as an input and adding the output voltage of a direct current constant voltage source to generate the output voltage to correspond only to the (n+1)-th bit to the output voltage of an (n) bit D-A converter when the input is a logic 1. CONSTITUTION:The analog output of a D-A converter 11 of seven bits and the output voltage of a direct current constant voltage source 12, which obtains the eighth bit (bit seven) as the input and controls an output so as to be the output voltage of a 0[V] at the time of a logic '0' to the output voltage to correspond to a case only the eighth bit (bit seven) is a logic '1' out of the data of eight bits when the input is the logic '1', are sent to an analog adder 13 and added. Then, the added output of the adder 13 is obtained as an analog output. Thus, the D-A conversion of the high resolution can be executed with using the D-A converter of the low resolution.
