LDC0851HDSGT datasheet by Texas Instruments

LDC0851HDSGT Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the LDC0851HDSGT?
  A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the high-frequency traces short and away from the power plane. Use a common mode choke or a ferrite bead to filter the power supply.
• How do I ensure accurate inductance measurements with the LDC0851HDSGT?
  Use a high-quality, low-ESR capacitor in the LC tank circuit. Ensure the inductor is properly connected and the PCB layout is optimized for minimal parasitic inductance. Calibrate the device using a known inductor value.
• What is the maximum operating frequency of the LDC0851HDSGT?
  The maximum operating frequency is 1 MHz, but it can be extended to 2 MHz with proper PCB layout and component selection. However, this may affect the accuracy of the inductance measurements.
• Can I use the LDC0851HDSGT for capacitance measurements?
  No, the LDC0851HDSGT is designed specifically for inductance measurements. It is not suitable for capacitance measurements. Use a different device, such as the LDC1612, for capacitance measurements.
• How do I handle noise and interference when using the LDC0851HDSGT?
  Use a shielded enclosure, keep the device away from noise sources, and use a low-pass filter or a ferrite bead to filter the power supply. Implement a noise-reducing algorithm in the firmware, such as averaging or median filtering.
