LINK HEADERS

Use the link headers to control the
configure the digital control voltage, and to isolate the LED
from the system. Table 2 lists the link header descriptions, and
how the links can be used on the evaluation board.
Use LK3 and LK4 to control the switches of the ADG5404F. Use
LK2 to enable or disable the device.
Position A ties to GND and sets the logic low, whereas Position B
ties to DC_V1 and sets the logic high.

LK1 allows the user to configure the drain state during an
overvoltage condition.
LK6 connects the on-board LDO regulator to the V
Remove the header to protect the LDO regulator from voltages
higher than 28 V or to use an alternative digital control voltage.
Change the header on LK5 to Position B to connect to DC_V1.
LK8 connects the LED to the digital power supply, and LK7
connects the FF pin or the SF pin of the

SMB CONNECTORS

Control the parallel interface of the
using the link headers of LK2 through LK4, or access the
interface by using the SMB connectors (A0/F0, A1/F1, and EN).
To use the SMB connectors, remove the link headers of LK2
through LK4. Use the FF/SF SMB connectors to access the FF/SF
digital outputs from the ADG5404F.
