LT1025CS8#TRPBF

LT1025CS8#TRPBF is a micropower thermocouple cold junction compensator. 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. It will operate with a supply voltage from 4V to 36V. Typical supply current is 80µA, resulting in less than 0.1°C internal temperature rise for supply voltages under 10V. It is used in applications such as thermocouple cold junction compensator, centigrade thermometer, temperature compensation network.

• Resistor divider accuracy is 60.9µV/°C typical at (TA = 25°C. VS = 5V)
• Line regulation is 0.02°C/V maximum at (TA = 25°C. VS = 5V)
• Load regulation is 0.2°C maximum at (TA = 25°C. VS = 5V)
• Divider impedance is 2.5Kohm typical at (TA = 25°C. VS = 5V)
• Temperature error at (TJ = 25°C 10mV/°C output) is 0.3°C typical at (TA = 25°C. VS = 5V)
• Operating temperature range from 0°C to 70°C
• 8-lead plastic SO package
