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
