ADP3000–SPECIFICATIONS
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.
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.
100 k resistor connected between a 5 V source and the AO pin.
