LTC1440CMS8#PBF

Overview

The LTC1440CMS8#PBF is a micropower single comparator with an integrated 1.182V reference, housed in an 8-lead MSOP package. It operates from a single 2V to 11V supply or dual ±1V to ±5.5V supply. The device features a typical supply current of 2.1µA and includes programmable hysteresis via the HYST pin. Its CMOS output stage can source up to 40mA while eliminating crowbar switching currents.

Feature Summary

Integrated 1.182V bandgap reference capable of driving bypass capacitors
Programmable hysteresis for noise immunity
Glitch-free CMOS outputs with high source current capability

Applications

Battery-powered system monitoring
Micropower threshold detectors
Window comparators
Oscillator circuits

Procurement Notes

Verify the #PBF suffix indicates lead-free compliance and RoHS adherence. Confirm the CMS8 designation matches the commercial temperature range (0°C to 70°C) and the specific MSOP-8 footprint requirements for your PCB layout.

Selection Notes

Select this component when ultralow quiescent current is critical alongside a built-in voltage reference. Ensure the input common mode range extends to within 1.3V of the positive rail meets your signal levels. Consider the LTC1441 if dual channels are needed without the reference.

Part Context

This part belongs to the LTC1440/LTC1441/LTC1442 family of ultralow power comparators. It serves as the single-channel variant with a fixed internal reference, distinct from the dual-channel LTC1441 which lacks the reference output.
