GENERAL DESCRIPTION
The
EVAL-ADG5248FEBZ
is the evaluation board for the
ADG5248F
, featuring an overvoltage protected 8:1 multiplexer.
The
ADG5248F
has overvoltage detection and protection circuitry
on the source pins and is protected against signals up to −55 V
and +55 V in both the powered and unpowered states.
Figure 1 shows the
EVAL-ADG5248FEBZ
in a typical evaluation
setup. The
ADG5248F
is soldered to the center of the evaluation
board, and wire screw terminals are provided to connect to each
of the source and drain pins. Three screw terminals power the
device, with a fourth terminal providing a user defined digital logic
supply voltage, if required. Alternatively, a low dropout (LDO)
regulator is provided for a 5 V digital logic supply and to supply
the LEDs, which are mounted to provide visual indication of the
fault status of the switch.
Full specifications on the
ADG5248F
are available in the
ADG5248F
data sheet, which must be consulted in conjunction
with this user guide when using the evaluation board.
