MAX6674

Cold-Junction-Compensated K-Thermocouple-to-Digital Converter (0°C to +128°C)


Please check latest availability status for a specific part variant.

Description

The MAX6674 cold-junction-compensation thermocouple-to-digital converter performs cold-junction compensation and digitizes the signal from a type-K thermocouple. The data is output in a 10-bit resolution, SPI™-compatible, read-only format.

This converter resolves temperatures to 0.125°C, allows readings as high as +128°C, and exhibits thermocouple accuracy of ±2°C for temperatures ranging from 0°C to +125°C.

The MAX6674 is available in a small, 8-pin SO package.
