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 LT5401I is guaranteed to meet specified performance from

–40°C to 85°C. The LT5401H is guaranteed to meet specified performance

from –40°C to 125°C and is 100% tested at these temperature extremes.

The LT5401MP is guaranteed to meet specified performance from –55°C

to 150°C and is 100% tested at these temperature extremes.

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: (∆R/R)RE specifies the following ratio matches:

RESISTOR RATIO

NOMINAL RATIO

(R1C + R1D)/(R1A + R1B)

(R2C + R2D)/(R2A + R2B)

(R1B + R1C + R1D)/(R1A)

(R2B + R2C + R2D)/(R2A)

(R1D)/(R1A + R1B + R1C)

0.5

(R2D)/(R2A + R2B + R2C)

0.5

Note 5: (∆R/R)RT specifies how well the (∆R/R)RE ratios match each other

when the 2 sets of LT5401 resistors are configured for nominally equal

ratios. This specification determines CMRR performance when the LT5401

is used to configure difference and fully differential amplifiers.

Note 6: (∆R/R)AVE specifies average (∆R/R)RE ratio matching when the 2

sets of LT5401 resistors are configured for nominally equal ratios. This

specification determines gain accuracy performance when the LT5401 is

used to configure difference and fully differential amplifiers.

Note 7: This parameter is not 100% tested.

Note 8: (∆R/R)SS specifies matching between the sum of R1 and R2 where

R1 = R1A + R1B + R1C + R1D and R2 = R2A + R2B + R2C + R2D.
