1 All limits at temperature extremes are guaranteed via correlation using standard statistical methods.

2This specification guarantees that both the high and low trip points of the comparator fall within the 1.20 V to 1.30 V range.

3The output voltage waveform will exhibit a saw-tooth shape due to the comparator hysteresis. The output voltage on the fixed output versions will always be within

the specified range.

4100 kΩ resistor connected between a 5 V source and the AO pin.
