NOTES
1This specification guarantees that both the high and low trip points of the comparator fall within the 1.20 V to 1.30 V range.
2The output voltage waveform will exhibit a sawtooth shape due to the comparator hysteresis. The output voltage on the fixed output versions will always be within
the specified range.
3100 kΩ resistor connected between a 5 V source and the AO pin.
Specifications subject to change without notice.
