MAX31850KATB+ Frequently Asked Questions (FAQs)

  • A good PCB layout for the MAX31850KATB+ involves keeping the analog and digital grounds separate, using a solid ground plane, and minimizing noise coupling between the RTD inputs and the digital signals. A 4-layer PCB with a dedicated analog ground layer is recommended.
  • The MAX31850KATB+ has an internal CJC sensor, but it's recommended to use an external CJC sensor for higher accuracy. The CJC sensor should be placed close to the RTD connections and connected to the CJCIN pin. The CJC temperature reading can then be used to compensate for the cold junction temperature.
  • The RTD connections should be wired in a 3-wire or 4-wire configuration to minimize noise and ensure accurate measurements. The 3-wire configuration is suitable for most applications, but the 4-wire configuration provides better noise rejection and is recommended for high-accuracy applications.
  • The MAX31850KATB+ has a built-in calibration mechanism that allows you to calibrate the device for your specific RTD sensor. You can use the CALMODE pin to enter calibration mode and then use the I2C interface to program the calibration coefficients. The calibration process typically involves measuring the RTD resistance at multiple temperatures and then calculating the calibration coefficients using the provided equations.
  • The maximum cable length for the RTD connections depends on the specific application and the noise environment. As a general rule, the cable length should be kept as short as possible to minimize noise pickup. However, cable lengths up to 100 meters are possible with proper shielding and noise filtering. It's recommended to use twisted-pair or shielded cables and to follow proper wiring and termination techniques.
