The MAX6675 performs cold-junction compensation
and digitizes the signal from a type-K thermocouple.
The data is output in a 12-bit resolution, SPI™-compatible,
This converter resolves temperatures to 0.25°C, allows
readings as high as +1024°C, and exhibits thermocouple
accuracy of 8LSBs for temperatures ranging from
0°C to +700°C.
