LTC1443CDHD#PBF

Overview

The LTC1443CDHD#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 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 variant. Outputs are TTL/CMOS compatible, capable of sourcing up to 40mA continuously. Propagation delay is typically 12µs at 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 part marking '1443' on the component body to confirm it is the LTC1443 variant rather than the LTC1444 or LTC1445. Ensure the order suffix matches the required commercial temperature range and lead-free finish specifications provided in the manufacturer's ordering information table.

Selection Notes

Select this component when low power consumption is critical alongside the need for multiple comparison channels in a compact footprint. The LTC1443 differs from the LTC1444/LTC1445 by having fixed ground on Pin 14 instead of programmable hysteresis, and utilizes a distinct internal reference voltage value.

Part Context

This device belongs to the LTC1443/LTC1444/LTC1445 family of ultralow power quad comparators. While sharing similar electrical characteristics and package options, the LTC1443 is distinguished by its specific internal reference voltage and dedicated ground pin configuration compared to the hysteresis-capable variants within the same series.
