GETTING STARTED

EVALUATION BOARD SETUP PROCEDURE

The EVAL-ADG5401FEBZ operates independently and does
not require any additional evaluation boards or software to
operate. An on-board ADP7142
the digital power supply for the LEDs and to manually control
the ADG5401F.
To supply the EVAL-ADG5401FEBZ with a dual power supply
of ±5 V to ±22 V or a single supply of +8 V to +44 V, connect
the EVAL-ADG5401FEBZ VSS pin and GND pin together on
J1. If the VDD pin voltage is greater than 40 V, remove the R6
resistor to protect the on-board
move the R10 resistor to the R11 pad (where the R11 resistor
can be populated, if required) to use an alternative digital
voltage supply connected to the EXT_VL pin on J1.

Figure 2. EVAL-ADG5401FEBZ Functional Block Diagram
To set up the EVAL-ADG5401FEBZ to perform a functionality
test, take the following steps:
1. Connect a power supply to the J1 connector. If a single supply
is required, connect the EVAL-ADG5401FEBZ VSS pin and
GND pin together on J1.
2. Use the LK1 link header to control the digital signals of the
switch channel on the

The green LED1 then illuminates to indicate that the switch is
operating normally.

ADG5401F as follows:
To open the switch and present it as an open
circuit, place LK1 in Position LO.
To close the switch and present it with a resistance
of approximately 6 Ω, place LK1 in Position HI.
