Abstract

PURPOSE:To make a high-speed D/A conversion possible, by comparing the ana- logue output of a D/A converter with an analogue signal input and by applying the comparison result to a logical operation circuit group controlled by a shift register and by inputting the output of this circuit group to the D/A converter. CONSTITUTION:Outputs of logical operation circuit groups 41-44 are applied to a D/A converter 9, and an analogue output A0 is compared with an analogue signal input AIN by a comparator 10. The output of the comparator 10 is applied to a D-FF 11 and is delayed by one bit and become digital signal outputs D1-D4 and is applied to logical operation circuit groups 41-44 as output timings of shift registers 21-24. When 5 clock pulses are applied to shift registers 21-24, and A/D conversion is completed.
