Product Description
LHE5400: Quad Matched Resistor Network
The LHE5400 is a quad resistor network designed for applications requiring excellent matching specifications across a wide temperature range. It offers superior matching performance, particularly when configured as a difference amplifier, leading to improved CMRR. All four resistors are independently accessible, providing flexibility for various circuit designs. This network is ideal for applications demanding precise ratiometric stability, such as difference amplifiers, voltage references, and bridge circuits. It is available in a space-saving 8-pin MSOP package and operates from 40C to 125C.
