GETTING STARTED
EVALUATION BOARD SETUP PROCEDURE
The
EVAL-ADG5248FEBZ
evaluation board operates
independently and does not require any additional evaluation
boards or software to operate. An on-board LDO regulator is the
digital power supply for the LEDs and manually controls the
ADG5248F
.
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 V
SS
and
GND together.
Set up a simple functionality test as follows:
1.
Connect a power supply to J3. Connect VSS and GND
together if a single supply is required.
2.
Ensure a 0 Ω resistor is inserted in R18 to use the on-board
LDO regulator, and that a 0 Ω resistor inserts into R20. SW1
through SW4 control the digital signals for the
ADG5248F
.
3.
LED1 and LED3 illuminate green to indicate that the
multiplexer is operating normally.
