Overview
The LTC1442IS8#TRPBF is a dual-channel analog comparator with an integrated 1.182V reference, housed in an 8-lead MSOP package. It operates on a single supply from 2V to 11V or a dual supply of ±1V to ±5.5V. The device features programmable hysteresis via the HYST pin and CMOS outputs capable of sourcing up to 40mA. Supply current is typically 3.5µA at 5V. Input common mode range extends from V– to V+ – 1.3V. Propagation delay is 15µs with 10mV overdrive.
Feature Summary
- Dual comparators with built-in 1.182V reference
- Programmable hysteresis control
- High-current CMOS output stage
- Glitch-free logic transitions
Applications
- Battery-powered system monitoring
- Threshold detectors
- Window comparators
- Oscillator circuits
Procurement Notes
Verify the specific suffix #TRPBF indicates lead-free tape and reel packaging. Confirm the IS8 designation corresponds to the industrial temperature grade (-40°C to 85°C) and the MSOP package style. Ensure compatibility with the required supply voltage range and input signal levels before integration.
Selection Notes
Select this component for applications requiring low quiescent current and adjustable hysteresis. The dual configuration allows independent threshold setting for each channel. Verify that the input signals remain within the specified common mode range relative to the negative supply rail during operation.
Part Context
This part belongs to the LTC1440/LTC1441/LTC1442 family of ultralow power comparators. While the LTC1440 offers single-channel performance and the LTC1441 provides dual channels without hysteresis control, the LTC1442 specifically includes programmable hysteresis functionality for both channels within the same compact footprint.
Replacement Considerations
Pin-compatible upgrades include the MAX921, MAX922, and MAX923 series. For quad-channel requirements, consider the LTC1443. Nanopower alternatives include the LTC1540.
