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 k

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

4

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

Specifications subject to change without notice.
