An on-board LDO regulator is provided as the digital power supply to manually control the ADG5208F. 1. 2. 3. 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. Connect a power supply to J3. Connect VSS and GND together if a single supply is required. Ensure that a 0 Ω resistor is inserted in R15 to use the onboard LDO regulator, and that a 0 Ω resistor is inserted in R14. SW1 through SW4 control the digital signals for the ADG5208F. See Table 1 for the logic control truth table.

EVAL-ADG5208FEBZ Block Diagram Rev. B | Page 3 of 12 UG-874 EVAL-ADG5208FEBZ User Guide EVALUATION BOARD HARDWARE The operation of the ADG5208F is evaluated using the EVALADG5208FEBZ. 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 ADG5208F 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 ADG5208F data sheet for more details. POWER SUPPLY Connector J3 provides access to the supply pins of the ADG5208F. VDD, GND, and VSS on J5 link to the appropriate pins on the ADG5208F. 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 Two screw connectors are provided to connect to both the source and drain pins of the ADG5208F. Additional subminiature Version B (SMB) connector pads are available if extra connections are required. The ADG5208F is overvoltage protected on the source side, and each source terminal (S1 to S8) can be presented with a voltage of up to +55 V or −55 V. See the ADG5208F 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. The resistor combined with the 0603 pads can be used to create a simple resistor-capacitor (RC) filter. The ADG5208F uses a parallel interface to control the operation of the switches. The switch operation can be manually controlled using the SW1 to SW4 switches, or an external controller can be interfaced directly to the control pins by using the SMB connectors (EN, A0, A1, and A2) and removing the 0 Ω R31, R33, R35 and R37 resistors. See Table 1 for the logic control truth table. Rev. B | Page 4 of 12 EVAL-ADG5208FEBZ User Guide UG-874 JUMPER SETTINGS SWITCHES AND 0 Ω RESISTORS Table 1. ADG5208F Truth Table Switches are used to control the ADG5208F 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. SW4 (A2) X1 L L L L H H H H Use Switch SW2 to Switch SW4 to control the switches of the ADG5208F. 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. Resistor 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.
