PURPOSE:To reduce the load of data processing based upon a processor by shifting digital data in plural ranges (conversion ranges) obtained from an A/D converter to a prescribed direction by the number of bits corresponding to the ranges and then inputting the shifted data to the processor. CONSTITUTION:An analog signal 1 is inputted to the A/D converter 3 and the converted parallel digital signal 2 and converted unit information 5 are outputted. The signal 2 is set up in a register 6 in a data conversion part 14. The information 5 is inputted to a shift pulse generating part 8 and shift pulses P corresponding to the conversion unit are outputted. Consequently, the data in the register 6 are shifted by the number of the shift pulses P and complement information F outputted from a complement generating part 15 is set up in the register 6. Thus, the value of the analog signal 1 is found out by the processor 4 on the basis of the product of the shifted digital information 9 and the number of shift pulses P. |
