GENERAL DESCRIPTION
The EVAL-ADG5249FEBZ is the evaluation board for the
ADG5249F, which features an overvoltage protected dual 4:1
multiplexer. The ADG5249F 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-ADG5249FEBZ in a typical evaluation
setup. The ADG5249F 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 used to provide a user defined digital
logic supply voltage, if required. Alternatively, a low dropout (LDO)
regulator is provided for 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 ADG5249F are available in the product
data sheet, which should be consulted in conjunction with this
user guide when using the evaluation board.
