LT1025CN8#PBF

LT®1025 is a micropower thermocouple cold junction compensator for use with type E, J, K, R, S and T thermocouples. It utilizes wafer level and post-package trimming to achieve 0.5°C initial accuracy. Special curvature correction circuitry is used to match the bow found in all thermocouples so that accurate cold junction compensation is maintained over a wider temperature range. Typical applications are thermocouple cold junction compensator, centigrade thermometer, temperature compensation network.
