LT1018IS8#TRPBF

Overview

The LT1018IS8#TRPBF is a micropower dual comparator in an 8-lead plastic SO package. It operates from a single supply of 1.1V to 40V. The device features a class B pull-up current source, eliminating the need for external resistive pull-ups. Maximum offset voltage is 1mV and maximum bias current is 15nA. Typical output drive capability is 70mA. Supply current is 110µA. The output stage allows driving loads connected to a supply more positive than the device.

Feature Summary

Features a class B pull-up current source that eliminates the need for external resistive pull-ups
Output stage designed to drive loads connected to a supply more positive than the device
On-chip trimming minimizes offset voltage while high gain keeps input referred errors low
Special circuitry prevents false output states even if the input is overdriven

Applications

Power supply monitors
Relay driving
Oscillators

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging with lead-free compliance. Confirm the IS8 designation corresponds to the industrial temperature range (-40°C to 85°C) and the 8-lead plastic SO package. Ensure compatibility with existing designs referencing older dual comparators such as 393 type devices due to pin compatibility.

Selection Notes

Select this component when higher speed and power are acceptable compared to the LT1017 variant. The internal pull-up current source simplifies design by removing external resistors. Verify that the 110µA supply current meets system power constraints. Ensure the operating voltage range between 1.1V and 40V aligns with the application requirements.

Part Context

This part belongs to the LT1017/LT1018 family of general purpose micropower comparators. While the LT1017 is optimized for lowest operating power, the LT1018 operates at higher power and higher speed. Both devices share similar electrical characteristics and pinouts, allowing for flexible selection based on speed versus power trade-offs.
