LTC1843CS8#PBF

LTC1843 is an ultralow power dual comparator with built-in reference. This device's hysteresis is easily programmed by using two resistors and the HYST pin. The comparators’ input operates from the negative supply to within 1.3V of the positive supply. The comparators’ output stage can typically sink greater than 20mA. By eliminating the cross-conduction current that normally happens when the comparators change logic states, power supply glitches are eliminated. It is widely used in application such as battery-powered system monitoring, threshold detectors, window comparators, oscillator circuits etc.

• Ultralow quiescent current is 3.5µA typical
