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 enhanced performance in difference amplifier configurations. All four resistors can be accessed and biased independently, providing versatility for various applications. The LHE5400 is ideal for applications demanding precise ratiometric stability, such as highly accurate difference amplifiers, voltage references, and bridge circuits. It is available in a space-saving 8-pin MSOP package and operates from 40C to 125C.
