MAX31855 Cold-Junction Compensated Thermocouple-to-Digital Converter IC

MAX31855 Cold-Junction Compensated Thermocouple-to-Digital Converter IC

The MAX31855 is a sophisticated thermocouple-to-digital converter that integrates cold-junction compensation, signal conditioning, and a 14-bit analog-to-digital converter (ADC) to provide temperature data directly from a thermocouple. The device supports Type K thermocouples (as well as J, N, T, E, R, S, and other types through different variants). The IC outputs the measured temperature data via a Serial Peripheral Interface (SPI), allowing easy interfacing with microcontrollers or other digital devices.

If you are in Nashik you can buy this Electronic Component at our local shop at New CBS, Nashik or you can place order online and get it delivered at your doorstep anywhere in India.

Features of MAX31855 Cold-Junction Compensated Thermocouple-to-Digital Converter IC

  • Wide Thermocouple Compatibility: Supports Type K thermocouples directly and other types (J, N, T, etc.) with specific variants.
  • Cold-Junction Compensation: Built-in cold-junction compensation ensures accurate temperature readings by adjusting for ambient temperature changes at the thermocouple’s connection point.
  • High Accuracy: Accuracy within ±2°C for readings from −200°C to +700°C with a Type K thermocouple.
  • Digital SPI Interface: Provides easy integration with microcontrollers or other SPI-enabled devices.
  • Wide Temperature Range: Can measure thermocouple temperatures from −200°C to +1350°C, depending on the thermocouple type.
  • 14-Bit ADC Resolution: Provides precise temperature readings with a resolution of 0.25°C.
