Overview
The LTC1841IS8#TRPBF is an ultralow power dual comparator housed in an 8-lead SOIC package. It operates from a single 2V to 11V supply or a dual ±1V to ±5.5V supply, drawing a typical quiescent current of 3.5μA. The device features open-drain outputs capable of sinking greater than 20mA and includes a built-in 1.182V reference with programmable hysteresis. Input voltage ranges extend from the negative supply to within 1.3V of the positive rail.
Feature Summary
- Ultralow quiescent current consumption for battery-powered applications
- Open-drain output stage capable of sinking significant load currents
- Built-in precision voltage reference with adjustable hysteresis capability
- Wide single and dual supply voltage operating range
Applications
- Battery-powered system monitoring
- Threshold detectors
- Window comparators
- Oscillator circuits
Procurement Notes
Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm that the IS8 designation corresponds to the industrial temperature range (-40°C to +85°C) and the narrow SOIC-8 package format required by your PCB layout constraints before finalizing procurement.
Selection Notes
Select this component for designs requiring minimal static power dissipation and precise threshold detection without external reference components. Ensure the application logic supports open-drain outputs and pull-up resistors are appropriately sized for the desired switching speed and voltage levels.
Part Context
This part belongs to the LTC1841/LTC1842/LTC1843 family of micropower comparators manufactured by Analog Devices. While the LTC1841 lacks an internal reference, the IS8 variant specifically denotes the industrial grade version packaged in a standard surface-mount plastic small outline configuration suitable for automated assembly.
