LTC1443CDHD#TRPBF

Overview

The LTC1443CDHD#TRPBF is an ultralow power quad comparator with a built-in reference, housed in a 16-lead (5mm × 4mm) plastic DFN package. It operates from a single 2V to 11V supply or dual ±1V to ±5.5V supply. The device features less than 8.5µA supply current over temperature and includes a 1.182V ±1% internal reference for the LTC1443 variant. Outputs are TTL/CMOS compatible, capable of sourcing up to 40mA continuously. Propagation delay is typically 12µs with 10mV overdrive.

Feature Summary

Ultralow quiescent current consumption across operating temperatures
Integrated voltage reference output capable of driving bypass capacitors without oscillation
TTL and CMOS compatible outputs with high continuous source current capability
Elimination of crowbar switching currents during logic state transitions

Applications

Battery-powered system monitoring
Threshold detectors
Window comparators
Oscillator circuits

Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature range. Confirm that the #TRPBF designation indicates tape and reel packaging. Ensure compatibility with existing board layouts regarding the 16-lead DFN footprint and exposed pad thermal connection requirements.

Selection Notes

Select this component for applications requiring minimal static power consumption while maintaining robust output drive capabilities. Consider the integrated reference for simplified threshold setting. Verify input common mode ranges against signal levels. Evaluate thermal dissipation needs given the low-profile DFN package constraints.

Part Context

This part belongs to the LTC1443/LTC1444/LTC1445 family of micropower comparators. It shares functional similarities with other members but differs in output configuration and reference voltage specifics. The CDHD suffix denotes the commercial temperature grade and DFN package format.
