Hi,

what are the symbols E1..E4 on the EVM schematics?

They are not reported on the BOM.

Hi Fabrizio,

These symbols are for spark gaps. These spark gaps are fabricated on the board with no components installed. Section 5 of this app note gives a brief discussion of spark gaps. http://www.ti.com/lit/an/slva232/slva232.pdf

Best regards,

Matt
