Digitally_controlled_threshold_detector

Figure 6-47 shows a MAX941 comparator combined with a MAX512 DAC to form a digitally controlled threshold detector. The analog signal to be compared is applied directly to the inverting input of the MAX941. The threshold point is set by the DAC output applied to the noninverting input. In turn, the DAC output is set by the serial digital input. As a result, the threshold can be set in eight discrete steps (depending on the serial input).
