SWITCHES AND 0 Ω RESISTORS
Switches control the ADG5209F manually and 0 Ω resistors
configure the digital control voltage. Table 2 shows a summary
of the switches and 0 Ω resistors and how they are used on the
evaluation board.
Use SW2 and SW3 to control the switches of the ADG5209F.
Position L (low) is tied to GND and sets the logic low, and
Position H (high) is tied to VL and sets the logic high.
Use SW1 to enable or disable the device. Position DIS (disable)
is tied to GND and disables the device, and Position EN (enable) is
tied to VL and enables the device.

R15 connects the on-board LDO regulator to the VDD supply.
Remove this resistor to protect the LDO regulator from voltages
higher than 28 V. Change the 0 Ω resistor to the R13 position to
use an alternative digital voltage connected to DC_V1.
SMB CONNECTORS
The parallel interface of the ADG5209F is controlled manually
using the link headers (SW1 to SW3), or it can be accessed using
the SMB connectors (EN, A0, and A1). To use the SMB
connectors, remove the 0 Ω R31, R33, and R35 resistors.
