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 N C, allows readings as high
as +1800 N C and as low as -270 N C, and exhibits thermo-
couple accuracy of ±2 N C for temperatures ranging from
-200 N C to +700 N C for K-type thermocouples. For full
range accuracies and other thermocouple types, see the
Thermal Characteristics specifications.
