An on-board LDO regulator is the digital power supply for the LEDs and manually controls the ADG5462F. 1. Supply the EVAL-ADG5462FEBZ 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. 2. 3. 4. J4 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 R18 to use the on-board LDO regulator and that a 0 Ω resistor is inserted in R20. Control the digital signals for the ADG5462F by using SW1. Verify that LED1 is green; this indicates that the mux is operating normally.

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. In this evaluation board, the ADG5462F 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 turns off, and the FF pin pulls low. See the ADG5462F data sheet for more details. POWER SUPPLY Connector J3 provides access to the supply pins of the ADG5462F. VDD, GND, and VSS link to the appropriate pins on the ADG5462F. For dual-supply voltages, the EVAL-ADG5462FEBZ is powered from ±5 V to ±22 V. For single-supply voltages, the GND and VSS terminals are connected together to power the EVAL-ADG5462FEBZ from 8 V to 44 V. Additionally, an onboard LDO regulator provides the digital control voltage. If necessary, connect a secondary voltage source to EXT_VL and use it to control the digital voltages. To use EXT_VL, move the 0 Ω resistor from R20 to R21. Do not expose the on-board LDO regulator to voltages greater than 28 V; remove R18 and supply an alternative digital voltage via EXT_VL, if required. INPUT SIGNALS Two screw connectors connect to both the source and drain pins of the ADG5462F. Additional subminiature Version B (SMB) connector pads are available if extra connections are required. The ADG5462F is overvoltage protected on the source side, and each source terminal (S1 to S4) can be presented with a voltage of up to +55 V or to −55 V. See the ADG5462F data sheet for more details. Each trace on the source and drain side includes two sets of 0603 pads, which 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 creates a simple resistor capacitor (RC) filter. OUTPUT SIGNALS The FF pin indicates when the device is operating normally or whether there is an overvoltage fault on one of the source pins. For visual indication, LEDs are mounted on the EVALADG5462FEBZ. When the device operates normally, the FF pin remains high, and LED1 illuminates green. If an overvoltage occurs at any of the source pins, the FF pin pulls low, and LED2 illuminates red.

Switch and 0 Ω Resistor Descriptions The switches manually control the ADG5462F, and 0 Ω resistors configure the digital control voltage, the voltage present on POSFV and NEGFV, to isolate the LED from the rest of the system. Label SW1 Use SW1 to configure the DR pin. The RAILS position is tied to GND and enables the drain to pull to POSFV or NEGFV during an overvoltage fault condition. The O/C position is tied to VL, and the drain is open-circuit condition. R18 connects the on-board LDO regulator to the VDD supply. Remove this resistor to protect the LDO regulator from voltages higher than 28 V. Move the 0 Ω resistor R20 to R21 to use an alternative digital voltage connected to EXT_VL. R35, R40, R42 R34, R39, R41 R42 R34 R20, R21 R39 R41 R20 Resistors R14 and R36 connect the LEDs to the digital power supply, and Resistors R37 and R13 connect the FF pin of the ADG5462F to the LED controls. R18 Resistors R34, R39, and R41 configure POSFV to either the voltage present on POSFV on J4 (VDD) or VL. Resistors R35, R40, and R42 configure NEGFV to either VSS, the voltage present on NEGFV on J4, or GND. R14, R36 SMB CONNECTORS Position O/C RAILS R35 R40 R37, R13 R15 The DR SMB connector can allow control via the external control signals. The FF SMB connector can access the FF digital output from the ADG5462F.
