Product Overview

The MAX31850KATB+ is a cold-junction compensated, 1-wire thermocouple to digital converter in 10 pin TDFN package. This sophisticated thermocouple to digital converter includes a built-in 14bit analogue to digital converter (ADC), cold-junction compensation sensing and correction, a digital controller, a 1-wire data interface and associated control logic. The 1-wire bus by definition requires only one data line and ground connection for communication with a central microcontroller. The data line requires a weak pull-up resistor since device is linked to the bus through a three-state or open-drain port. Four location address inputs simplify mapping of device to specific locations. This device has a unique 64bit serial code which allows multiple units to function on the same 1-wire bus. Hence it is simple to use one microcontroller (the master device) to monitor temperature from many thermocouples distributed over a large area.
  • Supply voltage range is 3V to 3.7V
  • "K" type thermocouple
  • Integration reduces design time and lowers system cost
  • 14bit, 0.25°C resolution
  • Measured temperature range from -270°C to +1372°C
  • Accuracy range of ±6°C
  • Detects thermocouple shorts to GND or VDD
  • Detects open thermocouple
  • 1-wire multiddrop capability simplifies multisensor systems
