IMPLEMENTATIONS
ShMC #1
ShMC #2
NOTES:
1) The system shown here uses
FET switches, however a valid alternative
is to simply use 24x IES5501’s without
FET switches.
2) Long track runs on the ShMC board
and backplane can sometimes result
in high frequency tuned circuits on either
side of the IES5501. If your layout is prone
to forming such tuned circuits, it is perfectly
acceptable to use a “traditional” damping
resistor (Rd) across the IES5501.
