Overview

  • Cold-Junction Compensation
  • Simple SPI-Compatible Serial Interface
  • 10 Bit, 0.125°C
  • Open Thermocouple Detection

    • The MAX6674 cold-junction-compensation thermocouple-to-digital converter performs cold-junction compensation and digitizes the signal from a type-K thermocouple. The data is output in a 10-bit resolution, SPI™-compatible, read-only format.

    This converter resolves temperatures to 0.125°C, allows readings as high as +128°C, and exhibits thermocouple accuracy of ±2°C for temperatures ranging from 0°C to +125°C.

    The MAX6674 is available in a small, 8-pin SO package.
