MAX31850TATB+ datasheet by Maxim Integrated Products

MAX31850TATB+ Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the MAX31850TATB+?
  The recommended PCB layout for the MAX31850TATB+ involves keeping the thermocouple traces as short as possible, using a dedicated ground plane, and avoiding running digital signals near the thermocouple inputs. Maxim provides a reference layout in the datasheet and application notes.
• How do I handle cold junction compensation (CJC) with the MAX31850TATB+?
  The MAX31850TATB+ has an internal CJC sensor, but it's recommended to use an external CJC sensor for higher accuracy. The internal sensor can be used for rough estimates, but an external sensor provides better temperature measurement accuracy.
• What is the maximum cable length for the thermocouple inputs on the MAX31850TATB+?
  The maximum cable length for the thermocouple inputs on the MAX31850TATB+ depends on the type of thermocouple and the noise environment. As a general rule, keep the cable length as short as possible (less than 10 feet) to minimize noise pickup and ensure accurate measurements.
• Can I use the MAX31850TATB+ with a non-standard thermocouple type?
  The MAX31850TATB+ is designed to work with standard thermocouple types (K, J, T, N, E, B, R, and S). While it's possible to use it with non-standard thermocouples, the accuracy and linearity of the measurements may be compromised. Consult the datasheet and application notes for guidance on using non-standard thermocouples.
• How do I calibrate the MAX31850TATB+ for optimal performance?
  Calibration of the MAX31850TATB+ involves setting the gain and offset registers to optimize the temperature measurement accuracy. Refer to the datasheet and application notes for a step-by-step calibration procedure.
