FDC2212DNTT Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate layer for the capacitive sensor's guard ring is recommended. The sensor's electrodes should be placed on the top layer, and the guard ring should be connected to the analog ground.
  • Calibration involves adjusting the internal capacitor arrays to match the sensor's capacitance. Use the device's built-in calibration mode and follow the procedure outlined in the datasheet to achieve accurate measurements.
  • The internal oscillator frequency is fixed at 1.5 MHz. It cannot be adjusted, but the device's clock frequency can be synchronized with an external clock signal if needed.
  • Use proper shielding, grounding, and layout techniques to minimize noise. Implement noise filtering and averaging techniques in software to improve measurement accuracy. Consider using a Faraday shield or a guard ring to reduce electromagnetic interference.
  • Yes, the FDC2212DNTT can be used for proximity sensing applications. The device's capacitive sensing capabilities can detect changes in capacitance caused by the presence or absence of an object.
