Hello Kuramochi-san,
the LDC1000 provides a frequency counter data by comparing the sensor oscillation frequency to the external reference clock frequency.
The LDC1000 is only recommended for metal type identification applications. For all other applications…
Hi Nishant,
the amplitude setting of '11' is a test mode that is not supported.
Have you verified that RP_MIN/RP_MAX and that the CFB capacitor are chosen correctly according tot he guidelines?
Have you considered using one of our newer devices…
Rachel,
Thank you for your prompt reply. I hadn't noticed that the 18 pF capacitors were not installed on the EVM. They are shown in the schematic and parts list in the FDC2214EVM User Guide (although the parts list shows a quantity of zero). I'm not…
Hello Matthew,
I apologize for the issues that you experienced, and am glad that you can now communicate with the EVM. Since you upgraded the firmware on the EVM, you should now also be able to use the new sensing solutions GUI with the EVM instead of…
Hello user,
The RP is the sensor impedance of the sensor resonant frequency. An RP value of 16.160kΩ = 16160Ω ≈ 16kΩ. This apps notes has more information on sensor design and the RP value: www.ti.com/.../snoa930
The LDC tools spreadsheet contains…
Hello Timothy, The new sensing solutions GUI is in the process of getting updated to address this issue. Please excuse any inconvenience the issue may cause in the meanwhile.
I understand you were using 4 LDC1000 EVMs, have you considered using one…
Hi Yada-san,
the capacitor provides a loop feedback path and is used for measurement stability of the converter. The LDC1000 has improved instructions for setting this capacitor; please use the instructions of the LDC1000 datasheet.
Have you considered…
Hello Teresa,
I apologize about the inconvenience. I believe that your EVM still has an old firmware revision. To make the EVM compatible with the Sensing Solutions GUI, please follow this procedure:
1. Please install the old LDC1000 GUI www.ti.com…
Other Parts Discussed in Thread: LDC0851 , LDC1101 Dear Sir,
We are looking for the ferrite sheet tape to be placed on the reference coil .
But still not sure this will resolve issue,
As with coil having lamination of 1mm is not having proximity…
