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.

of error from the LT5400 when configured in a difference amplifier (see
Difference Amplifier in Typical Applications):
The resistor contribution to CMRR can then be calculated in the following
way:
For LT5400 options with resistor ratio 1:1, the resistor contribution to
CMRR can be simplified:
CMRR ≈ (∆R/R)
