Split LED Bias Resistor for Optimum CMR
Figure 11 shows the recommended drive circuit for the
ACPL-x6xL that gives optimum common-mode rejection.
The two current setting resistors balance the common
mode impedances at the LED’s anode and cathode.
Common-mode transients can capacitively couple from
the LED anode (or cathode) to the output-side ground
causing current to be shunted away from the LED (which
is not wanted when the LED should be on) or conversely
cause current to be injected into the LED (which is not
wanted when the LED should be off ).
Figure 12 shows the parasitic capacitances (C

The resistors recommended in Figure 11 include both
the output impedance of the logic driver circuit and
the external limiting resistor. The balanced I
resistors help equalize the common mode voltage change
