Forum Post: RE: LDC1000EVM, CFB capacitor

Thanks.

And How about my last post:

"

Hi,

Now I'm testing another coil  with inductance 17 uF and Rp min = 200 ohms and Rp max = 5 K ohms. The parallel capacitor has value of 4.7 nF, so the frequency is 542 KHz.

 I got 1 V on CFB pin, but I could not read the real values of inductance and proximity data on "LDC 1000 EVM GUI". After that, I choose a filter capacitor for get  400 mV on CBF pin, and I got the real values of Inductance and Rp. The real values means the value measured in LCR Meter.

I would like to know more about the influence of the capacitor filter in the measures. In the datasheet it is unclear.

Thanks a lot."

Do you have any idea?
