General Description
The 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 MAX6675 is available in a small, 8-pin SO package.
