LTC1441CS8#TRPBF

Overview

The LTC1441CS8#TRPBF is a micropower dual comparator with a built-in 1.182V reference, operating from a single 2V to 11V supply or dual ±1V to ±5.5V supply. It features TTL/CMOS outputs capable of sourcing up to 40mA and sinking up to 5mA. The device operates within a commercial temperature range of 0°C to 70°C and utilizes an 8-lead plastic small outline (SOIC) package.

Feature Summary

• Dual comparator architecture with integrated 1.182V voltage reference
• TTL/CMOS compatible output stage providing high current drive 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 suffix #TRPBF indicates tape and reel packaging for automated assembly. Confirm the CS8 designation corresponds to the commercial temperature grade and SOIC package variant. Ensure compatibility with standard surface mount reflow profiles for 8-lead plastic packages.

Selection Notes

Select this component when dual independent comparison is required alongside a stable internal reference. The wide input common mode range extending to the negative supply simplifies circuit design. High output source current allows direct driving of loads without additional buffering stages.

Part Context

This part belongs to the LTC1440/LTC1441/LTC1442 family of ultralow power comparators. While the LTC1440 offers single-channel operation with programmable hysteresis and the LTC1442 provides dual channels with hysteresis, the LTC1441 specifically provides dual channels without adjustable hysteresis functionality.

Replacement Considerations

Pin-compatible upgrades include the MAX921, MAX922, and MAX923 series.
