Product Summary
The LT1025CN8 is a micropower thermocouple cold junction compensator for use with type E, J, K, R, S, and Tthermocouples. The LT1025CN8 utilizes wafer level and post package trimming to achieve 0.5°C initial accuracy. Special curvatur ecorrection circuitry is used to match the bow found in allthermocouples so that accurate cold junction compensationis maintained over a wider temperature range. A special kit is available (LTK001) which contains the LT1025CN8 and a custom tailored thermocouple amplifier. The amplifierand compensator are matched to allow a much tighter specification of temperature error than would be obtained by addingthe compensator and amplifier errors on a worst-case basis. The amplifier from this kit is available separately as LTKA0x
