GETTING STARTED
EVALUATION BOARD SETUP PROCEDURE
The EVAL-ADG5462FEBZ 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 ADG5462F.
Supply the EVAL-ADG5462FEBZ 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.
EVAL-ADG5462FEBZ User Guide
Follow these steps to conduct a functionality test:
1. Connect a power supply to J3. Connect VSS and GND
together if a single supply is required.
2. Ensure that a 0 ⦠resistor is inserted in R18 to use the
on-board LDO regulator and that a 0 ⦠resistor is inserted
in R20.
3. Control the digital signals for the ADG5462F by using SW1.
4. Verify that LED1 is green; this indicates that the mux is
operating normally.
