MAX31855K Cold Junction Compensated Thermocouple-to-Digital Converter 14 bit IC

MAX31855K Cold Junction Compensated K-Type Thermocouple to Digital Converter IC

The MAX31855K is a cold junction compensated thermocouple to digital converter with built-in 14bit analogue to digital converter in 8 pin NSOIC package. The device contains cold junction compensation sensing and correction, digital controller, SPI compatible interface and associated control logic. It is designed to work in conjunction with an external microcontroller (μC) in thermostatic, process control or monitoring applications.

The MAX31855K IC performs cold junction compensation and digitizes the signal from K type thermocouple with measuring temperature range of -200°C to + 1350°C.
