Product Description
LHE5400: Quad Matched Resistor Network
The LHE5400 is a quad resistor network designed for applications requiring excellent resistor matching over a wide temperature range. It offers superior matching specifications compared to independently matched resistors, leading to improved performance in difference amplifiers and other precision circuits. All four resistors can be accessed and biased independently, providing versatility for various applications. The LHE5400 is available in a space-saving 8-pin MSOP package and operates from 40C to 125C. Key applications include difference amplifiers, reference dividers, and precision summing/subtracting circuits.
