ANALOG DEVICES LTC1540IDD#TRPBF Analogue Comparator, Nano Power, 1 Channels, 60 µs, 2V to 11V, ± 1V to ± 5.5V, DFN, 8 Pins

LTC1540 is an ultralow power, single comparator with built-in reference. The comparator�s features include less than 0.6µA supply current over the commercial temperature range, a 1.182V ±2% reference, programmable hysteresis and TTL/CMOS outputs that sink and source current. The reference output can drive a bypass capacitor of up to 0.01µF without oscillation. The comparator operates from a single 2V to 11V supply or a dual ±1V to ±5.5V supply. Comparator hysteresis is easily programmed by using two resistors and the HYST pin. Each comparator�s 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 occur when the comparator changes logic states, power supply glitches are eliminated. Typical applications include battery-powered system monitoring, threshold detectors, window comparators and oscillator circuits.
