which is a 4-channel multiplexer. The ADG5404F has overvolt-

age 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 state.

Figure 1 shows the EVAL-ADG5404FEBZ in a typical setup.

The ADG5404F is soldered to the center of the board and wire

GETTING STARTED

EVALUATION BOARD SETUP PROCEDURE

The E VA L -ADG5404FEBZ board is designed to operate

independently and does not require any additional evaluation

boards or software. An on-board LDO regulator is provided for

digital control and supply voltage.

Supply the evaluation board with a dual power source of up to

±22 V or a single supply of up to 44 V. For single supply

operation, connect VSS to GND using J3.

Set up a simple functionality test as follows:

•Connect a power supply to J3. For single supply operation,

connect VSS to GND using J3.

•Insert the header for LK6 to use the on-board LDO

regulator, and place the header for LK5 to Position B.

•LK2 through to LK4 control the digital signals for each

switch on the ADG5404F.

•In Position A, the switch is open (off).

•In Position B, the S4 switch is closed (on) and has a

resistance of approximately 10 Ω.

•LED1 lights up to indicate that the switch is operating

normally.

EVALUATION BOARD HARDWARE

The operation of the ADG5404F is evaluated using the E VA L -

ADG5404FEBZ. Figure 1 shows a typical setup where only a

power supply and signal generator are required. Figure 2 shows

a block diagram of the main components of the evaluation

board.

The connectors on the board pass signals through the ADG5404F

switch. The source pins have fault detection circuitry that reacts

to an overvoltage. During an overvoltage event, the switch is

turned off and the FF pin is pulled low. The SF pin is pulled low

when the source where the overvoltage occurs is the one selected

by the A0/F0 and A1/F1 pins. See the ADG5404F data sheet for

further details.

POWER SUPPLIES

Connector J3 provides access to the supply pins of the

ADG5404F. VDD, GND, and VSS link to the appropriate pins

on the ADG5404F. For dual supply voltages, power the evaluation

board from ±5 V to ±22 V. For single supply voltages, connect

the GND and VSS terminals and power the evaluation board

with 8 V to 44 V. Additionally, an on-board LDO regulator is

provided for digital control voltage. If necessary, connect a

secondary voltage source to DC_V1 and use it as the digital

control voltage. To use DC_V1, place the header of LK5 into

Position A.

INPUT SIGNALS

Two screw connectors are provided to connect to both the

source and drain pins of the ADG5404F. Additional subminiature

Version B (SMB) connector pads have been laid out if extra

connections are required.

The ADG5404F is overvoltage protected on the source side, and

the maximum voltage that can be applied to S1 to S4 is −55 V or

+55 V. See the ADG5404F data sheet for more details.

Each trace on the source and drain side includes two sets of

gold pin connectors that are 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 gold pin connectors to create a simple

resistor/capacitor (RC) filter.

The ADG5404F uses parallel interface channels (A0/F0, A1/F1)

to control the operation of the switches. Use the headers on LK2

to LK4 to manually control the operation of the switches, or

connect an external controller directly to the control pins by

using the SMB connectors, A0/F0, A1/F1, and EN, and removing

the link headers on LK2 to LK4.

OUTPUT SIGNALS

There are two outputs on the ADG5404F. The FF pin indicates

when the device is operating normally or whether there is an

overvoltage fault on one of the source pins. The SF pin also

indicates when an overvoltage occurs on one of the source pins

and transitions low only when an overvoltage occurs on the

channel selected by the A0/F0 and A1/F1 inputs. For visual

indication, an LED is mounted on the evaluation board. Use

LK8 to connect the LED circuit. When the device is operating

normally, the FF pin remains high and the LED turns on. If an

overvoltage occurs at any of the source pins, the FF pin is pulled

low and the LED turns off.

The LK9 selector allows the user to choose which output controls

the LED. Putting the header on Position A allows the FF pin to

control the LED. On Position B, the SF pin controls the LED.

SMB connectors are provided to interface the evaluation board

with external controllers, and two gold pin connectors are provided

to connect a pull-up resistor between the FF and SF signals and

the digital supply.

The DR pin allows the user to choose the state of the drain pin

when the device is deactivated during an overvoltage. The LK1

selector allows the user to choose between open circuit and pulling

to the rails.

JUMPER SETTINGS

LINK HEADERS

Use the link headers to control the ADG5404F manually, to

configure the digital control voltage, and to isolate the LED

from the system. Table 2 shows a summary of the link headers

and how they are 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 is tied to GND and sets the logic low, whereas

Position B is tied to DC_V1 and sets the logic high.

B A B S3

B B B S4

1X = don’t care.

LK1 allows the user to configure the state of the drain during an

overvoltage condition.

LK6 connects the on-board LDO regulator to the VDD supply.

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 or SF pin of the ADG5404F to the LED.

SMB CONNECTORS

Control the parallel interface of the ADG5404F manually using

the link headers of LK2 to LK4, or access it using the SMB

connectors, A0/F0, A1/F1, and EN. To use the SMB connectors,

remove the link headers of LK2 to LK4. Use the FF/SF SMB

connectors to access the FF/SF digital outputs from the ADG5404F.
