ADG5208
NOTES
1. THE EXPOSED PAD IS CONNECTED INTERNALLY. FOR
INCREASED RELIABILITY OF THE SOLDER JOINTS AND
MAXIMUM THERMAL CAPABILITY, IT IS RECOMMENDED
THAT THE PAD BE SOLDERED TO THE SUBSTRATE, V
SS
.

13 11 V
DD
Most Positive Power Supply Potential.
14 12 GND Ground (0 V) Reference.
15 13 A2 Logic Control Input.
16 14 A1 Logic Control Input.
EP Exposed Pad
The exposed pad is connected internally. For increased reliability of the solder joints and
maximum thermal capability, it is recommended that the pad be soldered to the substrate, V
