MAX6675
Cold-Junction-pensated K-Thermocoupleto-Digital Converter (0°C to +1024°C)
General Description
The MAX6675 performs cold-junction pensation and digitizes the signal from a type-K thermocouple. The data is output in a 12-bit resolution, SPI-patible, 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.
The MAX6675 is available in a small, 8-pin SO package.
