Abstract
PURPOSE: To realize adjustment for the accuracy of the A/D converting device just by changing the bit number of the addition/subtraction counter. The A/D converting device uses the D/A converter which is capable of controlling its average value through control of the duty ratio.
CONSTITUTION: The binary coded digital data is stored in addition/subtraction counter 12, and the digital data of counter 12 is loaded in parallel to subtraction counter 13. Then flip-flop 16 is reset when the digital data is loaded to counter 13 and turned zero by the clock signal. The output signal of flip-flop 16 is then integrated 17, and this output value is compared with the input signal. Based on this comparison result, counter 12 is set to addition or subtraction.
