Description
The LT®5400 is a quad resistor network with excellent
matching specifications over the entire temperature range.
Matching is also specified when the LT5400 is configured
in a difference amplifier. This enhanced matching specifica-
tion 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.
