The is a Micropower Thermocouple Cold Junction Compensator for use with type E, J, K, R, S and T thermocouples. It utilizes wafer level 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. The LT1025 will operate with a supply voltage from 4 to 36V. Typical supply current is 80µA, resulting in less than 0.1°C internal temperature rise for supply voltages under 10V. A 10mV/°C output is available at low impedance, in addition to the direct thermocouple voltages of 60.9µV/°C E, 51.7µV/°C J, 40.3µV/°C K, T and 5.95µV/°C R, S. All outputs are essentially independent of power supply voltage.
