MAX31856 Datasheet Precision Thermocouple To Digital Converter

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: MAX31856 EVALUATION KIT AVAILABLE Precision Thermocouple to Digital Converter with Linearization.

General Description

The MAX31856 performs cold-junction pensation 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%.

Key Features

  • Provides High-Accuracy Thermocouple Temperature Readings.
  • Includes Automatic Linearization Correction for 8 Thermocouple Types.
  • ±0.15% (max, -20°C to +85°C) Thermocouple FullScale and Linearity Error.
  • 19-Bit, 0.0078125°C Thermocouple Temperature Resolution.
  • Internal Cold-Junction Compensation Minimizes System Components.
  • ±0.7°C (max, -20°C to +85°C) Cold-Junction Accuracy.
  • ±45V Input Protection Provides Robust System Performance.
