Product Overview

The LHE5400 is a quad matched resistor network designed for applications requiring excellent matching specifications over a wide temperature range. It offers superior matching compared to independently matched resistors, particularly in difference amplifier configurations, leading to improved CMRR performance. The device allows independent access and biasing of all four resistors, making it a versatile choice for precision applications such as difference amplifiers, reference dividers, and summing/subtracting circuits. It is available in an 8-lead MSOP package and operates from 40C to 125C.
