Matching is also specified when the LT5400 is configured in a difference amplifier. This enhanced matching specification guarantees CMRR performance to be up to 2× better than independently matched resistors. Allfourresistors canbeaccessedandbiasedindependently, making the LT5400 a convenient and versatile choice for any application that can benefit from matched resistors. These resistor networks provide precise ratiometric stability required in highly accurate difference amplifiers, voltage references and bridge circuits. The LT5400 is available in a space-saving 8-pin MSOP package, and is specified over the temperature range of - 55°C to 150°C.
