Hello,

Programming the LMP91300 is described in section 7.5 of the LMP91300 datasheet.

To learn how to evaluate a LC tank download the following Application Reports from the ti.com web site:

SNAA221A

SNOA936

The LMP91300 datasheet in section 8.2.2.2 also describes how to characterize a LC tank.

Dear Sir,

Thanks to update on the querry. We are planning for 4mm proximity using the device LMP91300. The surface area avilable is 12mm.
Let me know hoe to calculate values for LC tank circuit.

Thanks Mike,
I can be able to generate the CAD file. OD 7mm

Is there any application note for engaging LC tank circuit with the LMP91300 PCb in the sensor cylinder?

It is guided that C should be close possible to the coil. in generated layout there is space of 1 mm.

shall i modify to make it closer?
