tie analog ground to power ground (PowerPAD should tie to analog ground in this case). A star-connection
under PowerPAD is highly recommended.
8. It is critical that the exposed PowerPAD on the backside of the IC package be soldered to the PCB ground.
Ensure that there are sufficient thermal vias directly under the IC, connecting to the ground plane on the
other layers.
9. Decoupling capacitors should be placed next to the IC pins and make trace connection as short as possible.
10. All via size and number should be enough for a given current path.

Refer to the EVM design (SLUU396) for the recommended component placement with trace and via locations.
For the QFN information, refer to SCBA017 and SLUA271.
