LT1025. Micropower thermocouple cold junction Compensator U. FEATURES DESCRIPTIO . 80 A Supply Current The LT 1025 is a micropower thermocouple cold junction 4V to 36V Operation compensator for use with type E, J, K, R, S, and T. C Initial Accuracy (A Version) thermocouples. It utilizes wafer level and post-package Compatible with Standard Thermocouples trimming to achieve C initial accuracy. Special curvature (E, J, K, R, S, T) correction circuitry is used to match the bow found in all Auxiliary 10mV/ C Output thermocouples so that accurate cold junction compensation Available in 8-Lead PDIP and SO Packages is maintained over a wider temperature range. U The LT1025 will operate with a supply voltage from 4V to 36V. APPLICATIO S Typical supply current is 80 A, resulting in less than C. internal temperature rise for supply voltages under 10V. thermocouple cold junction Compensator A 10mV/ C output is available at low impedance, in addition Centigrade Thermometer to the direct thermocouple voltages of V/ C (E), Temperature Compensation Network V/ C (J), V/ C (K, T) and V/ C (R, S).
