7.3.2.4.1 Unipolar Inputs Out-of-Range Alarms
The AMC7836 device provides out-of-range detection for the five external unipolar ADC inputs (LV_ADC16 through LV_ADC20, pins 35 through 39). Figure 55 shows the out-of-range detection block. When the measurement is out-of-range, the corresponding alarm bit in the alarm status 0 register (address 0x70) is set to 1 to flag the out-of-range condition. The values in the ADC upper and lower Threshold registers (address 0x80 through 0x93) define the upper and lower bound thresholds for all five inputs.
