On top of first page: General Description 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, read-only format. This converter resolves temperatures to 0.25°C, allows readings as high as +1024°C, and exhibits thermocouple accuracy of 8 LSBs for temperatures ranging from 0°C to +700°C. Result is given as a multiple of 0.25 °C, after a divison by 4 you get a multiple of 1 °C with a fractional part of two bits. | |
