Could you please let me know if ADG5434 & ADG1434 EPAD is connected to VSS internally .
We see that it seems not to be connected internally .
ADG1434: Exposed Pad. The exposed pad is tied to the substrate, VSS .
ADG5434: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, VSS .
With best regards and wishes
