A | Page 2 of 10 EVAL-ADG5404FEBZ User Guide UG-790 GETTING STARTED EVALUATION BOARD SETUP PROCEDURE Set up a functionality test as follows: The EVAL-ADG5404FEBZ board operates independently and does not require any additional evaluation boards or software. An on-board LDO regulator provides digital control and the 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. • Connect a power supply to J3. For single-supply operation, connect VSS to GND using J3. Insert a header at LK6 to use the on-board LDO regulator, and set the header at LK5 to Position B. LK2 through LK4 control the digital signals for each switch on the ADG5404F. • When these three links are in Position A, the switches are open (off). • When these three links are in Position B, the S4 switch is closed (on), and it has a resistance of approximately 10 Ω. When LK9 is in Position A, LED1 lights up to indicate that no faults were detected at any of the source pins. • • J3 VDD GND VSS LK6 VSS ADP7142 GND VDD ADG5404F J1:S1 J2:D1 S1 D B LK3 LK5 J3 A B J1:S4 S4 A DC_V1 LK4 B SF A LK2 B FAULT DETECTION + SWITCH DRIVER A0/F0 A1/F1 EN LK9 B A FF DR A LK8 LK1 B LK7 12894-002 LED1 A Figure 2. EVAL-ADG5404FEBZ Block Diagram Rev. A | Page 3 of 10 UG-790 EVAL-ADG5404FEBZ User Guide EVALUATION BOARD HARDWARE Use the EVAL-ADG5404FEBZ to evaluate the ADG5404F. 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 turns off and the FF pin pulls low. The SF pin pulls 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 provides 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, set the header at LK5 to Position A. INPUT SIGNALS Two screw connectors connect the source and drain pins of the ADG5404F. If extra connections are required, additional Subminiature Version B (SMB) connector pads are laid out. The ADG5404F is overvoltage protected on the source side, and the maximum voltage that can be applied to S1 through 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 for placing a load on the signal path to ground. Place a 0 Ω resistor in the signal path, or it 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. Use parallel interface channels (A0/F0 and A1/F1) to control the operation of the ADG5404F switches. Use the headers on LK2 through 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 by removing the link headers on LK2 through LK4. OUTPUT SIGNALS The ADG5404F has two outputs. The FF pin indicates when the device operates 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 operates normally, the FF pin remains high, and the LED turns on. If an overvoltage occurs at any of the source pins, the FF pin pulls low, and the LED turns off. The LK9 selector allows the user to choose which output controls the LED. Setting the header to Position A allows the FF pin to control the LED. Setting the header to Position B, the SF pin controls the LED. SMB connectors can interface the evaluation board with external controllers, and two gold pin connectors can 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 deactivates during an overvoltage. The LK1 selector allows the user to choose between open circuit and pulling to the rails. Rev. A | Page 4 of 10 EVAL-ADG5404FEBZ User Guide UG-790 JUMPER SETTINGS LINK HEADERS SMB CONNECTORS 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 lists the link header descriptions, and how the links can be used on the evaluation board. Control the parallel interface of the ADG5404F manually by 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. 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. Table 1.

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 pin or the SF pin of the ADG5404F to the LED.
