NOTES
1
This specification guarantees that both the high and low trip point of the comparator fall within the 1.20 V to 1.30 V range.
2
The 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.
3
100 k
resistor connected between a 5 V source and the AO pin.
*All limits at temperature extremes are guaranteed via correlation using standard statistical methods.
Specifications subject to change without notice.
