Overview
The LTC1441IS8#PBF is a micropower dual comparator with an integrated 1.182V reference, housed in an 8-lead plastic SO 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 3.5µA and TTL/CMOS compatible outputs capable of sourcing up to 40mA. Input common mode range extends from the negative supply to within 1.3V of the positive supply.
Feature Summary
- Dual comparator architecture with integrated precision voltage reference
- TTL/CMOS compatible output stage capable of high source current
- Wide operating supply voltage range for flexible system integration
Applications
- Battery-powered system monitoring
- Threshold detectors
- Window comparators
- Oscillator circuits
Procurement Notes
Verify the specific suffix #PBF indicates lead-free compliance and the IS8 designation confirms the industrial temperature grade and SOIC package type. Confirm that the datasheet specifications apply to the full operating temperature range as indicated by the electrical characteristics table markers.
Selection Notes
Select this component when a dual comparator configuration is required alongside a stable internal reference. The wide input common mode range and high output drive capability make it suitable for interfacing with various logic families without additional buffering components.
Part Context
This part belongs to the LTC1440/LTC1441/LTC1442 family of ultralow power comparators. While the LTC1440 offers single-channel functionality and the LTC1442 provides adjustable hysteresis, the LTC1441 specifically delivers dual independent channels with a fixed reference output.
