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 CMRR performance in difference amplifier configurations. All four resistors are independently accessible and biasable, providing versatility for various precision applications. Available in a space-saving 8-pin MSOP package, the LHE5400 is suitable for difference amplifiers, reference dividers, and precision summing/subtracting circuits.
