Product Summary

The LTC1442IS8#TR is an ultralow power dual comparator with built-in references. The comparator features less than 3.7μA supply current over temperature (LTC1440), a 1.182V ±1% reference, programmable hysteresis (LTC1440/LTC1442) 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 applications of the LTC1442IS8#TR include Battery-Powered System Monitoring, Threshold Detectors, Window Comparators, Oscillator Circuits.
