Product Summary

The LTC1440CMS8#TRPBF is an ultralow power single and 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 and TTL/CMOS outputs that sink and source current. The reference output can drive a bypass capacitor of up to 0.01uF without oscillation. The applications of the LTC1440CMS8#TRPBF are (1)Battery-Powered System Monitoring; (2)Threshold Detectors; (3)Window Comparators; (4)Oscillator Circuits.
