General Description
The MAX31850/MAX31851 cold-junction compensat ed, 1-WireM thermocouple-to-digital converters perform cold-junction compensation and digitize the signal from a K-, J-, N-, T-, S-, R-, or E-type thermocouple. The converters resolve temperatures to 0.25NC, allow readings as high as +1768NC and as low as -270NC, and exhibit thermocouple accuracy of 8 LSBs (2NC) for temperatures ranging from -200NC to +700NC.
