    I will be making event driven detection measurmenents to where an event will register a 30mV-200mV analog pulse in my detector. Now I will be using 12 detectors spatially arranged to measure the spatial extent of the measurement (Where it happened). I want to convert each of these analog pulses into a uniform digital signal. No matter the incoming voltage I want the same digital output, really just a count that something happened there. I do not know much about DAC and would like suggestions on the appropriate one. I will be feeding the digital siganl to a USB data aquisition device. The event signal couls happen pretty fast (@ 100 events/s) or slow (@1event/s). Any help would be appreciated.

    100 events/s is relatively slow.
    You do not need an ADC. Use an analog comparator to detect the pulses. The output of the comparator is digital.
