LTC1842CS8#TRPBF

Overview

The LTC1842CS8#TRPBF is an ultralow power dual comparator with a built-in 1.182V reference, housed in an 8-lead SOIC package. It operates from a single 2.5V to 11V supply or a dual ±1.25V to ±5.5V supply. The device features a typical quiescent current of 3.5μA and open-drain outputs capable of sinking greater than 20mA. Hysteresis is programmable via the HYST pin using two resistors. Input voltage range extends from the negative supply to within 1.3V of the positive supply.

Feature Summary

Built-in 1.182V reference output
Programmable hysteresis capability
Open-drain outputs sink over 20mA
Eliminates cross-conduction current spikes

Applications

Battery-powered system monitoring
Threshold detectors
Window comparators
Oscillator circuits

Procurement Notes

Verify the #TRPBF suffix indicates tape-and-reel packaging distinct from tube variants. Confirm the CS8 designation corresponds to the commercial temperature range (0°C to 70°C). Ensure compatibility with the specific 8-lead SOIC footprint required by the design.

Selection Notes

Select this component when a fixed internal reference is required alongside dual comparison functions. It is suitable for applications needing adjustable hysteresis without external components. Verify that the 2.5V minimum supply voltage aligns with the system's lowest operating condition.

Part Context

This part belongs to the LTC1841/LTC1842/LTC1843 family of micropower comparators. While the LTC1841 lacks a reference and the LTC1843 shares the same reference and hysteresis features as the LTC1842, they differ in input pin configurations. The LTC1842 provides specific noninverting inputs for both channels.
