Product Summary

The LTC1842CS8#TR is an ultralow power dual comparator with built-in reference (LTC1842/LTC1843). The comparators feature less than 5.7mA supply current over temperature, a 1.182V ±1% reference, programmable hysteresis and open-drain outputs that sink current. The reference output can drive a bypass capacitor of up to 0.01mF without oscillation. The LTC1842CS8#TR 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. The LTC1842CS8#TR is available in SO-8 packages. Applications are battery-powered system monitoring, threshold detectors, window comparators, oscillator circuits.
