LTC1443IDHD#PBF

Overview

The LTC1443IDHD#PBF 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 a dual ±1V to ±5.5V supply. The device features less than 8.5µA supply current over temperature and includes an internal 1.182V ±1% reference for the LTC1443. Outputs are TTL/CMOS compatible, capable of sourcing up to 40mA continuously. Propagation delay is typically 12µs with 10mV overdrive. The input common mode range extends from the negative supply to within 1.3V of the positive supply.

Feature Summary

Ultralow quiescent current consumption across operating temperatures
Integrated voltage reference output capable of driving bypass capacitors without oscillation
TTL/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 industrial temperature grade (-40°C to 85°C) indicated by the 'I' suffix in the part number against design requirements. Confirm the 16-lead DFN package dimensions match the PCB footprint layout. Ensure the internal reference voltage specification aligns with circuit threshold calculations before finalizing procurement.

Selection Notes

Select this component when low power consumption is critical alongside integrated reference functionality. The LTC1443 provides fixed reference accuracy suitable for applications not requiring programmable hysteresis, unlike the LTC1444/LTC1445 variants. Consider the split supply capability of the LTC1443 if dual polarity operation is necessary compared to other family members.

Part Context

This part belongs to the LTC1443/LTC1444/LTC1445 family of ultralow power quad comparators. While sharing similar core architecture and low power characteristics, the LTC1443 is distinguished by its fixed 1.182V reference and TTL/CMOS outputs, whereas other variants offer different reference voltages or open-drain outputs.
