The MAX6675 is a temperature module that uses a K-type thermocouple to measure temperatures from 0°C to 1024°C. It includes a driver and amplifier. The MAX6675 digitizes the signal from the thermocouple and outputs the data in a 12-bit resolution, SPI-compatible, read-only format.

The MAX6675 has the following features:

  • 0°C to 1024°C temperature range
  • 12-bit resolution
  • SPI-compatible, read-only format
  • 0.25°C temperature resolution
  • 8 LSBs thermocouple accuracy for temperatures ranging from 0°C to +700°C
  • Small-outline IC, narrow (0.15in)
  • Requires a power source from 3.0V to 5V
  • Draws 1.5mA maximum

The MAX6675 is discontinued and replaced with the MAX31855.
