MAX31856MUD+

The MAX31856MUD+ is a precision thermocouple to digital converter with linearization in 14 pin TSSOP package. The MAX31856 performs cold-junction compensation and digitizes the signal from any type of thermocouple. The output data is formatted in degrees Celsius. This converter resolves temperatures to 0.0078125°C, allows readings as high as +1800°C and as low as -210°C (depending on thermocouple type) and exhibits thermocouple voltage measurement accuracy of ±0.15%. The thermocouple inputs are protected against overvoltage conditions up to ±45V. A lookup table (LUT) stores linearity correction data for several types of thermocouples (K, J, N, R, S, T, E and B). Line frequency filtering of 50Hz and 60Hz is included, as is thermocouple fault detection. A SPI-compatible interface allows selection of thermocouple type and setup of the conversion and fault detection processes.

• Supply voltage range is 3V to 3.6V
• Operating temperature range from -55°C to 125°C
• Includes automatic linearization correction for 8 thermocouple types
• 19bit, 0.0078125°C thermocouple temperature resolution
• ±0.7°C (max, -20°C to +85°C) cold-junction accuracy
• Detects open thermocouples, over and undertemperature fault detection
