Thank you very much for your help.
Thanks to you, I understand a little more about LDC0851.
Also, could you please tell me about the sensor coil?
In the LDC sensor design, there is no mention of an "iron core" in the inductor coil design, although there is a picture of what appears to be an "iron core" in Figures 2.17 ~ 2.19. Should I assume that an "iron core" is not generally used in LDC systems?
I would like to use the calculation results for the inductor coil as support for the inductor coil, so please explain the case where an "iron core" is used.
