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.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: The instantaneous difference between the highest voltage applied
to any pin and the lowest voltage applied to any other pin should not
exceed the Absolute Maximum Rating. This includes the voltage across
any resistor, the voltage across any pin with respect to the exposed pad of
the package, and the voltage across any two unrelated pins.
Note 3: In order to keep the junction temperature within the Absolute
Maximum Rating, maximum power dissipation should be derated at
elevated ambient temperatures.
Note 4: The LT5400C is guaranteed functional over the operating
temperature range of –40°C to 85°C. The LT5400C is designed,
characterized and expected to meet specified performance from –40°C to
85°C but is not tested or QA sampled at these temperatures. The LT5400I
is guaranteed to meet specified performance from –40°C to 85°C. The
LT5400H is guaranteed to meet specified performance from –40°C to
125°C and is 100% tested at these temperature extremes. The LT5400MP
is guaranteed to meet specified performance from –55°C to 150°C and is
100% tested at these temperature extremes.
Note 5: This parameter is not 100% tested.
Note 6: (∆R/R)CMRR (Matching for CMRR) is a metric for the contribution
of error from the LT5400 when used in a difference configuration using
the specific resistor pairs of R1/R2 and R4/R3. See Difference Amplifier,
Instrumentation Amplifier, and Differential Amplifier circuits in the Typical
Applications section for examples.

For LT5400 options with resistor ratio 1:1, the resistor contribution to
CMRR can be simplified:
CMRR ≈ (∆R/R)CMRR
