resistor matching solution Legendsemi LHE5400A-6MMA for precision summing subtracting and reference circuits

Product Overview

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