LT5401
ELECTRICAL CHARACTERISTICS Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 5:
(∆R/R)RT specifies how well the (∆R/R)RE ratios match each other may cause permanent damage to the device. Exposure to any Absolute when the 2 sets of LT5401 resistors are configured for nominally equal Maximum Rating condition for extended periods may affect device ratios. This specification determines CMRR performance when the LT5401 reliability and lifetime. is used to configure difference and fully differential amplifiers.
Note 2:
The LT5401I is guaranteed to meet specified performance from
Note 6:
(∆R/R)AVE specifies average (∆R/R)RE ratio matching when the 2 –40°C to 85°C. The LT5401H is guaranteed to meet specified performance sets of LT5401 resistors are configured for nominally equal ratios. This from –40°C to 125°C and is 100% tested at these temperature extremes. specification determines gain accuracy performance when the LT5401 is The LT5401MP is guaranteed to meet specified performance from –55°C used to configure difference and fully differential amplifiers. to 150°C and is 100% tested at these temperature extremes.
Note 7:
This parameter is not 100% tested.
Note 3:
In order to keep the junction temperature within the Absolute
Note 8:
(∆R/R)SS specifies matching between the sum of R1 and R2 where Maximum Rating, maximum power dissipation should be derated at R1 = R1A + R1B + R1C + R1D and R2 = R2A + R2B + R2C + R2D. elevated ambient temperatures.
Note 4:
(∆R/R)RE specifies the following ratio matches:
RESISTOR RATIO NOMINAL RATIO
(R1C + R1D)/(R1A + R1B) 1 (R2C + R2D)/(R2A + R2B) 1 (R1B + R1C + R1D)/(R1A) 2 (R2B + R2C + R2D)/(R2A) 2 (R1D)/(R1A + R1B + R1C) 0.5 (R2D)/(R2A + R2B + R2C) 0.5 Rev. 0 For more information www.analog.com 5 Document Outline Features Applications Typical Application Description Absolute Maximum Ratings Order Information Pin Configuration Electrical Characteristics Typical Performance Characteristics Pin Functions Block Diagram Applications Information Typical Applications Package Description Typical Application Related Parts
