DESCRIPTION
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.

FEATURES
■ 80µA Supply Current
■ 4V to 36V Operation
■ 0.5°C Initial Accuracy (A Version)
■ Compatible with Standard Thermocouples (E, J, K, R, S, T)
■ Auxiliary 10mV/°C Output

APPLICATIONS
■ Thermocouple Cold Junction Compensator
■ Centigrade Thermometer
■ Temperature Compensation Network
