8.1.1.1 Operation

The basic comparator compares the input voltage (VIN) on one input to a reference voltage (VREF) on the other input. In the Figure 8-1 example below, if VIN is less than VREF, the output voltage (VO) is logic low (VOL). If VIN is greater than VREF, the output voltage (VO) is in a high-Z state. Table 8-1 summarizes the output conditions. The output logic can be inverted by simply swapping the input pins.

Table 8-1 Output Conditions
Inputs ConditionOutput
IN+ > IN-HIGH (VOH)
IN+ = IN-Indeterminate (chatters - see Hysteresis)
IN+ < IN-LOW (VOL)
