LT1025 Micropower Thermocouple Cold Junction Compensator UW U FEATURES s 80µA Supply Current s 4V to 36V Operation s 0.5°C Initial Accuracy (A Version) s Compatible with Standard Thermocouples (E, J, K, R, S, T) s Auxiliary 10mV/°C Output s Available in 8-Lead PDIP and SO Packages U APPLICATIO S s Thermocouple Cold Junction Compensator s Centigrade Thermometer s Temperature Compensation Network DESCRIPTIO The 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.
