FDC2112QDNTRQ1 Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate analog ground plane is recommended. Keep the analog and digital grounds separate and connect them at a single point. Use a 10nF capacitor between the VCC and GND pins to filter out noise.
  • Use a shielded cable to connect the sensor to the FDC2112QDNTRQ1. Ensure the sensor is properly calibrated and the measurement frequency is set correctly. Also, use a low-pass filter to remove noise and ensure the measurement is taken when the sensor is in a stable state.
  • The FDC2112QDNTRQ1 can measure capacitances up to 100pF with an accuracy of ±1.5%. However, the maximum capacitance range may vary depending on the sensor used and the application.
  • The FDC2112QDNTRQ1 has a digital interface that can be connected to a microcontroller using I2C or SPI protocols. Use a level shifter if the microcontroller operates at a different voltage level. Ensure the microcontroller can handle the data rate of the FDC2112QDNTRQ1.
  • The FDC2112QDNTRQ1 has a typical power consumption of 1.5mA at 1.8V supply voltage. However, the power consumption may vary depending on the operating frequency and the sensor used.
