DESCRIPTION
The LT^®5400 is a quad resistor network with excellent
matching specifications over the entire temperature
range.
All four resistors can be accessed and biased independently,
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.
