MAX31850
Overview
The MAX31850/MAX31851 cold-junction compensated, 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.
- 14-Bit, 0.25NC Resolution
- Integrated Cold-Junction Compensation
- Available for Multiple Thermocouples Types: Supports K-, J-, N-, T-, and E-Type (MAX31850); S- and R-Type (MAX31851)
- Detects Thermocouple Shorts to GND or VDD
- Detects Open Thermocouple S 1-Wire Multiddrop Capability Simplifies Multisensor Systems
- 1-Wire Interface (Read-Only); Power Can Be Obtained from Interface (Parasite-Powered Mode)
