Product Description
Product Overview
The LHE5400 is a quad resistor network designed for high-precision applications requiring excellent resistor matching. It offers superior matching specifications over the entire temperature range, enhancing performance in difference amplifiers by providing up to 2x better CMRR compared to independently matched resistors. All four resistors are independently accessible and biasable, making it a versatile component for applications demanding precise ratiometric stability, such as voltage references and bridge circuits. The LHE5400 is available in a compact 8-lead MSOP package and operates from 40C to 125C.
