MAXIM INTEGRATED / ANALOG DEVICES MAX31850KATB Thermocouple Converter

The MAX31850KATB+ is a cold-junction compensated, 1-wire thermocouple-to-digital converter in a 10-pin TDFN package. It features a built-in 14-bit ADC, cold-junction compensation, and a digital controller that supports multiple sensors via a unique 64-bit serial code. Designed for K-type thermocouples, it operates between -270°C and +1372°C with a resolution of 0.25°C and a typical accuracy of ±6°C. The device detects shorts to GND or VDD, open thermocouples, and reduces system cost by integrating complex functions, making it ideal for industrial, medical, and instrumentation applications.
