PROBLEM TO BE SOLVED: To provide a multipoint-simultaneous high speed analog/digital conversion device that simultaneously converts a plurality of analog input signals to digital signals in a simple circuit configuration.SOLUTION: The multipoint-simultaneous high speed analog/digital conversion device includes a plurality of analog/digital conversion sections for converting a plurality of analog input signals to digital output signals, and a control circuit (3) for comprehensively controlling the analog/digital conversion sections. The analog/digital conversion sections include a basic block and an additional block. The basic block has a comparison signal generator (1) for outputting a comparison signal repeating a monotonic increase or monotonic decrease, and a clock generator (2). The basic block and the additional block each have a comparator (4) for comparing the analog input signal with the comparison signal, and a counter (5). The control circuit controls the comparison signal generator such that the period of generating the digital output signals falls on a changeless period in which the comparison signal does not monotonically increase or monotonically decrease. |
