The MAX31856MUD+ by Analog Devices is a precision thermocouple to digital converter designed for accurate temperature measurements. It performs cold-junction compensation and digitizes thermocouple signals, outputting data in degrees Celsius. This device offers a temperature resolution of 0.0078125°C and can measure temperatures ranging from -210°C to +1800°C, depending on the thermocouple type.
Key features include a thermocouple voltage measurement accuracy of ±0.15% and input protection against overvoltage conditions up to ±45V. It supports 8 types of thermocouples (K, J, N, R, S, T, E, and B) with automatic linearization correction. The converter includes 50Hz/60Hz line frequency filtering and thermocouple fault detection capabilities, such as open thermocouple detection and over/undertemperature fault detection.
Designed for ease of system integration, the MAX31856MUD+ minimizes system components with its internal cold-junction compensation. It operates with a typical current of 1.2 mA and features a SPI-compatible interface for thermocouple type selection and setup. The device is housed in a 14-TSSOP package and is suitable for surface mounting.
Applications for this converter include temperature controllers, industrial ovens, furnaces, environmental chambers, and other industrial equipment requiring precise temperature monitoring.
