Maxim Integrated’s 1-Wire Thermocouple-to-Digital Converters Simplify Multisensor Industrial and Medical Designs
Maxim Integrated Products  (Planegg, Germany) has 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. Features include:
- High integration and accuracy: Converters achieve ±2.0 °C accuracy while combining multiple discrete component functions into a single chip.
- Simplified designs: The devices’ 1-Wire interface allows for a large number of devices on the same communication bus. Their four dedicated address pins uniquely identify up to 16 sensor locations.
- Versatility: The MAX31850 is available for K, J, N, T, and E thermocouple types and the MAX31851 is available for R and S thermocouple types.
