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 8LSBs for temperatures ranging from 0°C to 700°C. The MAX6675 is available in a small, 8-pin SO package.
