2.3.3 Input Filtering

Common-mode and differential input filtering can be applied to the circuit using C3, C4, C6. These components are unpopulated by default. When selecting component values for the capacitors, the recommendation is to make C4 approximately ten times larger than C3 and C6. Note that any capacitor and resistors selected must be rated for the inputs being applied.
