MAX31855 Cold-Junction Compensated Thermocouple-to-Digital Converter General Description The MAX31855 performs cold-junction compensation and digitizes the signal from a K-, J-, N-, T-, S-, R-, or E-type thermocouple.
The data is output in a signed 14-bit, SPI-compatible, read-only format.
This converter resolves temperatures to 0.
25°C, allows readings as high as +1800°C and as low as -270°C, and exhibits thermocouple accuracy of ±2°C for temperatures ranging from -200°C to +700°C for K-type thermocouples.
For full range accuracies and other thermocouple types, see the Thermal Characteristics specifications.
