1、The value of L9 is 8.2ohm, but L9 should not be an inductor, so is this value 8.2nH?

Hi Lixin,

L9 is 8.2-Ohm although the eval board and schematic shows an inductor, the bill materials usually will reflect what is populated in those component areas.

So, in fact, using an 8.2-ohm resistor is the correct choice, right?

4

Yes 8.2-Ohms is being populated for L9.

thank you ! i will change it!
