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.
TheLT1025willoperatewithasupplyvoltagefrom4Vto36V.
Typical supply current is 80
A, 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 60.9
V/°C (E),
51.7
V/°C (J), 40.3V/°C (K, T) and 5.95V/°C (R, S). All
outputs are essentially independent of power supply voltage.
A special kit is available (LTK001) which contains an LT1025
and a custom tailored thermocouple amplifier. The amplifier
and compensator are matched to allow a much tighter specifi-
cation of temperature error than would be obtained by adding
the 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 SO
package for temperatures between 0
°C and 70°C.
