Description

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.

Features

  • S Integration Reduces Design Time and Lowers System Cost.
  • 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 Interfac.

EVALUATION KIT AVAILABLE MAX31850/MAX31851 Cold-Junction Compensated, 1-Wire Thermocouple-to-Digital Converters General Description 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. Communication with the master microcontroller is over a 1-Wire bus that by definition requires only one data line (and ground) for communication.
