Abstract
PURPOSE:To obtain a fast and highly integrated semiconductor integrated circuit, by outputting the maximum value or the minimum value by inputting the output of a comparator directly to an OR circuit or an AND circuit. CONSTITUTION:The titled circuit is constituted of a first holding part 7 which holds the output of the comparator, a second holding part 8 which holds a peak value (maximum value), the OR circuit 9 which takes out a larger value out of the values held at the holding parts 7 and 8, and a control circuit 10 which controls a timing to transmit the maximum value held at the holding part 8 to an encoder circuit. The output of the OR circuit is held at the second holding part 8, and it is inputted to the encoder circuit 5 by operating the control circuit 10. Thus, by constituting an A/D converter of parallel comparison system, it is possible to output the peak value of analog input and an A/D conversion value to an output terminal 6.
