2.1.3 Recommended EMC protection circuitry
The purpose of the following recommendation is to give generic EMC protection guidelines for the
SCA1020. EMC susceptibility is highly dependent on the PCB layout and therefore the component
values given here can be different depending on the actual PCB layout. With the following circuitry
and properly designed PCB the part will pass 200V/m EMC susceptibility tests.
Please note that only channel 1 output protection circuitry is presented. Similar kind of circuit must
be also at the channel 2 output.
