UG-042
The power and ground from the screw terminal block (if
installed) are connected to the Side 1 power and ground pads
of the DUT and provide power and ground to pull-up and pull-
down resistors and terminations.
The ADuM640x devices differ from the rest of the isoPower
devices in that they have an additional power supply input on
Pin 7. This replaces the RC
ADuM5402, ADuM5403, and ADuM5404. This pin must be
bypassed and connected to VDD1 for proper operation of the
ADuM640x. It is recommended that a 0.1 µF capacitor be
installed at R5 and a 0 W resistor at R4. The ADuM640x devices
are not compatible with power sharing; therefore, an ADuM5000
should not be installed at U1 when using the ADuM640x.
Side 2 Power Supply Connections
The Side 2 connections are different from those on Side 1. With
standard iCoupler devices, these connections are power supply
inputs for Side 2. However, with isoPower devices such as the
ADuM540x, these same connections can be power outputs for
off-board circuits. In addition, they can be configured as an
independent power supply for the project area.

Power is connected to the terminal block connector (if installed)
labeled IO_1D, as shown in Figure 5. Power is connected to
IO_1D Pin 1 at the top, and ground is connected to Pin 2.
Provisions for adding in-line inductors for noise isolation or for
isolating the jacks from the on-board power connections have
been made with the inclusion of Z6 and Z7. These positions are
populated with 0 Ω resistors to connect power from the
ADuM540x to the IO_1D terminal block.
When standard iCoupler isolators are installed, the Z6 and Z7
pads should be populated with 0 Ω resistors to connect the power
jacks to the power pins of the DUT. Replace these resistors with
inductors if noise isolation is required.
When isoPower devices are installed on the board, the power
configuration required can vary greatly, depending on the
demands of the application. With 0 Ω resistors or inductors
installed at Z6 and Z7, the power jacks can provide power from
the isoPower device to an external device.
