LTC1440IS8#TRPBF, Analog Comparators Ultralow Pwr 1x/2x Comp w/ Ref

LTC1440 is an ultralow power single/dual comparator with built-in reference. The reference output can drive a bypass capacitor of up to 0.01µF without oscillation. Its input operates from the negative supply to within 1.3V of the positive supply. The comparator output stage can continuously source up to 40mA. By eliminating the cross-conducting current that normally happens when the comparator changes logic states, the power supply glitches are eliminated. Typical applications are battery-powered system monitoring, threshold detectors, window comparators, oscillator circuits.
