Product Summary

The MAX6675ISA is a Cold-Junction-Compensated K-Thermocouple-to-Digital Converter. The MAX6675ISA performs cold-junction compensation and digitizes the signal from a type-K thermocouple. The data is output in a 12-bit resolution, SPI-compati-ble, read-only format. This converter resolves temperatures to 0.25℃, allows readings as high as +1024℃, and exhibits thermocouple accuracy of 8LSBs for temperatures ranging from 0℃ to +700℃. The MAX6675ISA is available in a small, 8-pin SO package. The applications of the MAX6675ISA include Industrial, Appliances, HVAC and Automotive.
