Product Description
LHE5400: Quad Matched Resistor Network
The LHE5400 is a quad resistor network offering excellent matching specifications across its operating temperature range. It is designed for applications requiring precise ratiometric stability, such as difference amplifiers, voltage references, and bridge circuits. The device provides enhanced matching, guaranteeing up to 2x better CMRR performance compared to independently matched resistors. All four resistors can be accessed and biased independently, offering versatility. The LHE5400 is available in a space-saving 8-pin MSOP package and operates from 40C to 125C.
