Article Does any MAX31855 version support all thermocouple types?

No, each MAX31855 version can only be paired with the corresponding thermocouple type. For example, MAX31855K can only be used with K-type thermocouples, MAX31855J can only be used with J-type thermocouples, etc. Each MAX31855 version is trimmed to a specific thermocouple and cold-junction sensitivity, which is dependent on thermocouple type based on NIST standards.

As an alternative, MAX31856 can support multiple thermocouple types and includes internal linearization.
