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 amplifier configurations. All four resistors are independently accessible, providing flexibility for various applications that benefit from matched resistors, such as precision summing/subtracting circuits and voltage references. The device is available in a compact 8-lead MSOP package and operates from 40C to 125C.
