Maxim Integrated Products, Inc. announced that it is now sampling the MAX31850/ MAX31851 cold-junction-compensated, 1-Wire® thermocouple-to-digital converters. The devices achieve ±2.0°C accuracy (not including sensor nonlinearity) while integrating all of the functions required for a complete thermocouple-to-digital solution. Additionally, the MAX31850/MAX31851’s 1-Wire interface allows multiple sensor locations to communicate and draw power over a single data line, greatly simplifying wiring requirements. Designers can use the MAX31850 or MAX31851 instead of multiple discret e components for accurate temperature measurement in medical, industrial, and solar applications. Because thermocouple output voltages are small and cold-junction compensation is needed to achieve accurate results, the digitization of thermocouple signals can be a challenge. The MAX31850/ MAX31851 are the industry’s first solution to integrate a discrete analog-to-digital converter (ADC), a highly accurate reference, a temperature sensor for cold-junction compensation, and a 1-Wire bus interface into a single chip. The versatile converters operate with several types of thermocouples, speeding system design, lowering system cost, and reducing the bill of materials (BOM).
