The present invention relates to an integrating A/D converter and a radiation-sensitive sensor device comprising such a converter. The A/D converter comprises an integrating element, which during fixed time intervals integrates an input signal, and further a comparator, to the one input of which said integrated value is continuously supplied and to the other input of which a reference value is supplied, and a device comprising a clock pulse generator, which supplies a counter, which during said time intervals counts upwards or downwards from a starting value, and which, based on the output signal from the comparator, determines whether the integrated signal in upwards counting exceeds or equals the reference value and in downwards counting is lower than or equals the reference value and, if so, at which point of time in the time interval, which is a measure of the size of the signal. |
