GENERAL DESCRIPTION
The EVAL-ADG5243FEBZ is the evaluation board for the
ADG5243F, which features three independently controlled
single-pole/double-throw (SPDT) switches. The ADG5243F 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-ADG5243FEBZ in a typical evaluation
setup. The ADG5243F is soldered to the center of the evaluation
board, and screw terminals are provided to connect to each of
the source and drain pins. Three screw terminals power the
device, and a fourth terminal provides a user defined digital
voltage, if required. Alternatively, a low dropout (LDO) regulator
is provided for 5 V digital voltage control and to supply the LED,
which is mounted to provide visual indication of the fault status
of the switch.
Full specifications on the ADG5243F are available in the
product data sheet, which should be consulted in conjunction
with this user guide when using the evaluation board.
