Hello Nat,
the LDC1051 is active and can be used for new designs, but we better parts available. In most LDC1051 applications, the LDC1312 is a more suitable alternative. I recommend considering the following devices:
- The high-resolution multi-channel…
Hello Byeongguk,
the LDC1000 (and also our other LDC devices) do not have an analog output.
The LDC1000 is only recommended for metal type identification applications. For all other applications, I recommend using one of our newer devices; They offer…
I have now had a look at the LDC1101EVM. The same thing is happening there.
The first 8 samples have a much larger sampleperiod than the next 248 samples. At least 2 to 1 difference.
I can't connect with EVM software so I gather the data with my own…
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…
