LDC2114PWT Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the application note SLAA701, which includes guidelines for component placement, routing, and grounding to minimize noise and ensure optimal performance.
  • Calibration involves adjusting the device's internal registers to compensate for parasitic capacitance and inductance. TI provides a calibration procedure in the datasheet, which involves measuring the device's output with a known inductor and adjusting the registers accordingly.
  • The LDC2114PWT can measure inductance up to 100 kHz, but the maximum frequency range depends on the specific application and the quality of the inductor being measured. TI recommends consulting the datasheet and application notes for more information on frequency range and measurement limitations.
  • Yes, the LDC2114PWT can measure inductance in a multi-layer PCB, but it's essential to consider the effects of layer stacking and vias on the measurement. TI recommends using a 4-layer PCB with a solid ground plane and minimizing vias near the inductor to ensure accurate measurements.
  • To minimize noise and interference, use a low-noise power supply, add decoupling capacitors, and ensure good grounding and shielding. TI also recommends using a ferrite bead or a common-mode choke to filter out high-frequency noise.
