MAX6675ISA+T
Cold-Junction-Compensated K-Thermocoupleto-Digital Converter (0°C to +1024°C)
传感器接口 K Thermocouple to Digital Converter
General Description
The MAX6675ISA+T 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 MAX6675ISA+T MAX6675 is available in a small, 8-pin SO package.
