MAX6675ISA+T

MAX6675ISA+T is a cold-junction-compensated K-thermocouple to-digital converter. It performs cold-junction compensation and digitizes the signal from a type-K thermocouple. The data is output in a 12bit 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. It is used in applications such as industrial, appliances, and HVAC.
