Cold-Junction Compensated
Thermocouple-to-Digital Converter
Applications Information
Noise Considerations
Because of the small signal levels involved, thermocou-
ple temperature measurement is susceptible to power-
supply coupled noise. The effects of power-supply noise
can be minimized by placing a 0.1 F F ceramic bypass
capacitor close to the V CC pin of the device and to GND.
The input amplifier is a low-noise amplifier designed to
enable high-precision input sensing. Keep the thermo-
couple and connecting wires away from electrical noise
sources. It is strongly recommended to add a 10nF
ceramic surface-mount differential capacitor, placed
across the T+ and T- pins, in order to filter noise on the
thermocouple lines.
Thermal Considerations
Self-heating degrades the device’s temperature measure-
ment accuracy in some applications. The magnitude of the
temperature errors depends on the thermal conductivity
of the device package, the mounting technique, and the
effects of airflow. Use a large ground plane to improve the
device’s temperature measurement accuracy.
Maxim Integrated
The thermocouple system’s accuracy can also be
improved by following these precautions:
? Use the largest wire possible that does not shunt heat
away from the measurement area.
? If a small wire is required, use it only in the region
of the measurement, and use extension wire for the
region with no temperature gradient.
? Avoid mechanical stress and vibration, which could
strain the wires.
? When using long thermocouple wires, use a twisted
pair extension wire.
? Avoid steep temperature gradients.
? Try to use the thermocouple wire well within its tem-
perature rating.
? Use the proper sheathing material in hostile environ-
ments to protect the thermocouple wire.
? Use extension wire only at low temperatures and only
in regions of small gradients.
? Keep an event log and a continuous record of thermo-
couple resistance.
