GENERAL DESCRIPTION
The E VA L -ADG5209FEBZ is the evaluation board for the
ADG5209F and features an overvoltage protected dual 4:1
multiplexer. The ADG5209F has overvoltage detection and
protection circuitry on the source pins and is protected against
signals up to −55 V and +55 V in both the powered and
unpowered states.
Figure 1 shows the E VA L -ADG5209FEBZ in a typical evaluation
setup. The ADG5209F is soldered to the center of the evaluation
board, and wire screw terminals are provided to connect to each
of the source and drain pins. Three screw terminals are used to
power the device, with a fourth terminal used to provide a user
defined digital logic supply voltage, if required. Alternatively, a
low dropout (LDO) regulator is provided for 5 V digital logic
supply.
Full specifications on the ADG5209F are available in the
ADG5209F data sheet, which should be consulted in
conjunction with this user guide when using the evaluation
board.

GETTING STARTED
EVALUATION BOARD SETUP PROCEDURE
The EVAL-ADG5209FEBZ evaluation board is designed to
operate independently and does not require any additional
evaluation boards or software to operate. An on-board LDO
regulator is provided as the digital power supply to manually
control the ADG5209F.
Supply the evaluation board with a dual power source of up to
±22 V or a single supply of up to 44 V by connecting VSS and
GND together.
A functionality test can be set up as follows:
1. Connect a power supply to J5. Connect VSS and GND
together if a single supply is required.
2. Ensure a 0 Ω resistor is inserted in R15 to use the on-board
LDO regulator, and that a 0 Ω resistor is inserted in R14.
3. SW1 through SW3 control the digital signals for the
ADG5209F.

EVALUATION BOARD HARDWARE
The operation of the ADG5209F is evaluated using the E VA L -
ADG5209FEBZ. Figure 1 shows a typical evaluation setup
where only a power supply and signal generator are required.
Figure 2 shows the block diagram of the main components of
the evaluation board.
Using this evaluation board, the ADG5209F passes signals from
either the source or drain connectors. The source pins have fault
detection circuitry that react to an overvoltage event. During an
overvoltage event, the channel on which the fault occurs is
turned off. See the ADG5209F data sheet for more details.
POWER SUPPLY
Connector J5 provides access to the supply pins of the
ADG5209F. VDD, GND, and VSS on J5 link to the appropriate
pins on the ADG5209F. For dual supply voltages, the evaluation
board can be powered from ±5 V to ±22 V. For single supply
voltages, the GND and VSS terminals must be connected together,
and power the evaluation board with 8 V to 44 V. Additionally,
an on-board LDO regulator is provided for a digital control
voltage. If necessary, a secondary voltage source can be
connected to EXT_VL and used to control the digital voltages.
To use EXT_VL, move the 0 Ω resistor from R14 to R13. Do not
expose the on-board LDO regulator to voltages greater than
28 V; remove R15 and supply an alternative digital voltage via
EXT_VL, if required.
INPUT SIGNALS
Four screw connectors are provided to connect to both
the source and drain pins of the ADG5209F. Additional
subminiature Version B (SMB) connector pads are available if
extra connections are required. The ADG5209F is overvoltage
protected on the source side, and each source terminal (S1A to S4A
and S1B to S4B) can be presented with a voltage of up to +55 V or
−55 V. See the ADG5209F data sheet for more details.
Each trace on the source and drain side includes two sets of
0603 pads, which can be used to place a load on the signal path
to ground. A 0 Ω resistor is placed in the signal path and can be
replaced with a user defined value. Use the resistor combined
with the 0603 pads to create a simple resistor-capacitor (RC)
filter.
The ADG5209F uses a parallel interface to control the operation of
the switches. The switch operation can be manually controlled
using the SW1 to SW3 switches, or an external controller can be
interfaced directly to the control pins by using the SMB connectors
(EN, A0, and A2) and removing the 0 Ω R31, R33, and R35
resistors.

JUMPER SETTINGS
SWITCHES AND 0 Ω RESISTORS
Switches are used to control the ADG5209F manually and
0 Ω resistors are used to 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 is tied to GND and sets the logic low, and Position H
is tied to VL and sets the logic high.
Use SW1 to enable or disable the device. Position DIS is tied to
GND and disables the device, and Position EN 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 Position R13 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 of SW1 to SW4, or it can be accessed using
the SMB connectors, EN, A0, A1, and A2. To use the SMB
connectors, remove the 0 Ω R31, R33, and R35 resistors.
