LTC1441IS8#TRPBF

Overview

The LTC1441IS8#TRPBF is a micropower dual comparator with a built-in 1.182V reference, housed in an 8-lead SOIC package. It operates from a single 2V to 11V supply or dual ±1V to ±5.5V supplies. The device features CMOS outputs capable of sourcing up to 40mA and sinking up to 5mA. Supply current is typically 3.5µA at 5V. Input common mode range extends from the negative supply to within 1.3V of the positive supply. Propagation delay is 15µs with 10mV overdrive.

Feature Summary

Dual comparators with integrated 1.182V bandgap reference
CMOS output stage capable of high source current
Wide input common mode range including negative supply rail
Glitch-free switching eliminates supply current spikes

Applications

Battery-powered system monitoring
Threshold detectors
Window comparators
Oscillator circuits

Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging for automated assembly. Confirm the 'I' grade designation matches the required -40°C to 85°C operating temperature range. Ensure the SOIC-8 footprint aligns with the PCB layout specifications provided in the datasheet package outline section.

Selection Notes

Select this component when dual independent comparison channels are required alongside a stable internal voltage reference. The wide input common mode range allows operation near the negative rail. High output drive capability simplifies interfacing with digital logic without additional buffering stages.

Part Context

This part belongs to the LTC1440/LTC1441/LTC1442 family of ultralow power comparators. The LTC1441 specifically provides two independent comparator channels without programmable hysteresis pins, unlike the LTC1440 and LTC1442 which include HYST functionality. It serves as a pin-compatible upgrade for older MAX921/922/923 devices.
