GETTING STARTED
EVALUATION BOARD SETUP PROCEDURE
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.
Set up a functionality test as follows:
•
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.
