MAX31855

Cold-Junction Compensated

Thermocouple-to-Digital Converter

General Description

Features

The MAX31855 performs cold-junction compensation

and digitizes the signal from a K, J, N, T, or E type ther-

mocouple. (Contact the factory for S and R type thermo-

couples.) 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 2NC for temperatures ranging from

-200NC to +700NC for K-type thermocouples. For full

range accuracies and other thermocouple types, see the

Thermal Characteristics specifications.

S Cold-Junction Compensation

S 14-Bit, 0.25NC Resolution

S Versions Available for K, J, N, T, and E Type

Thermocouples (Contact Factory for S and R Type

Availability) (see Table 1)

S Simple SPI-Compatible Interface (Read-Only)

S Detects Thermocouple Shorts to GND or V

S Detects Open Thermocouple
