MAX31855PMB1 Peripheral Module
General Description
The MAX31855PMB1 peripheral module provides the
necessary hardware to interface the MAX31855 cold-
junction compensated thermocouple-to-digital converter
to any system that utilizes PmodK-compatible expansion
ports. The IC performs cold-junction compensation and
digitizes the signal from a thermocouple. Versions of the
IC are available that operate with a K-, J-, N-, T-, R-, or
E-type thermocouple. This module is set up to operate
with a K-type thermocouple. The data is output in a signed
14-bit, SPI-compatible, read-only format. This converter
resolves temperatures to 0.25NC, allows readings as high
as +1800NC and as low as -270NC, and exhibits thermo-
couple accuracy of Q2NC for temperatures ranging from
-200NC to +700NC for K-type thermocouples.
For full range accuracies, other thermocouple types, and
detailed information regarding operation of the IC, refer to
the MAX31855 IC data sheet.
Note: K-type thermocouple is not included with Maxim
Peripheral Module collections.
