EVM Schematics of the Triple and Quad Isolators

This multifunctional EVM is designed with the signal paths displayed in

Figure 2

through

Figure 5

for the

evaluation of the ISO7131, ISO7140, ISO7141 and ISO7142.

Note that each input channel has a 50-

load resistor to ground. Each output channel has a 4.7-pf load

capacitor to ground. These are not populated by default. Instead, there are pads on the board for the user
to install either a resistor or capacitor, depending on the desired configuration.
