The LT1025 is a micropower thermocouple cold junctioncompensator for use with type E, J, K, R, S, and Tthermocouples. It utilizes wafer level and post-packagetrimming to achieve 0.5°C initial accuracy. Special curvaturecorrection circuitry is used to match the "bow" found in allthermocouples so that accurate cold junction compensationis maintained over a wider temperature range.
The LT1025 will operate with a supply voltage from 4V to 36V.Typical supply current is 80µA, resulting in less than 0.1°Cinternal temperature rise for supply voltages under 10V.A 10mV/°C output is available at low impedance, in additionto the direct thermocouple voltages of 60.9µV/°C (E),51.7µV/°C (J), 40.3µV/°C (K, T) and 5.95µV/°C (R, S). Alloutputs are essentially independent of power supply voltage.
A special kit is available (LTK001) which contains an LT1025and a custom tailored thermocouple amplifier. The amplifierand compensator are matched to allow a much tighter specificationof 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.
The LT1025 is available in either an 8-pin PDIP or 8-pin SOpackage for temperatures between 0°C and 70°C.
