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
GND together.

EVAL-ADG5248FEBZ User Guide
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.
