Product Overview

The LT1025CN#PBF 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.
  • 80µA Supply current
  • 0.5°C Initial accuracy (A version)
  • Compatible with standard thermocouples (E, J, K, R, S, T)
  • Auxiliary 10mV/°C output
