Maxim Integrated's 1-Wire Thermocouple-to-Digital Converters Simplify Multisensor Industrial and Medical Designs

Maxim's converters integrate all the functions required for a complete and highly accurate thermocouple-to-digital solution.

SAN JOSE, Calif., July 10, 2013 — (PRNewswire) — Maxim Integrated Products, Inc. (NASDAQ: MXIM) today 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 discrete 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). The MAX31850/MAX31851 also identify open or shorted thermocouples that could result in erroneous temperature readings or system faults. A microcontroller can read the fault status at any time to help ensure uptime and prevent costly repairs.
