19-2241; Rev 1; 8/02 Cold-Junction-Compensated K-Thermocoupleto-Digital Converter (0°C to +128°C) General 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. o Cold-Junction Compensation o Simple SPI-Compatible Serial Interface o 10 Bit, 0.
