Precision matched resistors are used in a wide range of high-precision instrumentation applications, including measurement and data acquisition, wireless RF, networking, automated test, medical, industrial control and military equipment.
The LT®5400 is a four-channel, precision matched resistor series designed for high performance signal conditioning applications such as differential amplifiers, precision voltage dividers, precision gain stages and bridge circuits. These thin film resistors offer excellent resistor-to-resistor matching and excellent long-term drift characteristics in a small package.
The LT5400's matching performance is further enhanced with "CMRR matching," a new metric used to guarantee CMRR performance when using differential circuit configurations. The CMRR matching error of the LT5400 is guaranteed to be better than 0.005% over the entire specified temperature range, which is a twofold improvement over the 0.01% matching error when using separate resistors.
