Abstract
PURPOSE: To enable to convert required for the D/A converter having the bit number less than the data to be converted, by subtracting the input data from a given digital data preset, in the D/A converter.
CONSTITUTION: For example, when the digital data 1 in 12 bits in converted from 380H (hexadecimal number) to 420H, the digital data set circuit 3 outputs the digital data of 370H. The data 1 and the output data of the circuit 3 are subtracted at the subtractor 4 to output the digital data 5 changed in the range of 10H to B0H (hexadecimal number). Since the D/A converter 6 handles the output 5 changed from 10H to B0H, the number of bits of the converter 6 is sufficient with 8 bits, and the analog signal 7 corresponding to the changing part of the digital data can be obtained.
