GETTING STARTED
EVALUATION BOARD SETUP PROCEDURE
The EVAL-ADG5208FEBZ evaluation board operates
independently and does not require any additional evaluation
boards or software to operate. An on-board LDO regulator is
provided as the digital power supply to manually control the
ADG5208F.
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 VSS and
GND together.

A functionality test can be set up as follows:
1. Connect a power supply to J3. Connect VSS and GND
together if a single supply is required.
2. Ensure that a 0 Ω resistor is inserted in R15 to use the on-
board LDO regulator, and that a 0 Ω resistor is inserted
in R14.
3. SW1 through SW4 control the digital signals for the
ADG5208F. See Table 1 for the logic control truth table.
