NOTES:
FOR 2 LAYERS BOARD, LAYOUT
PGND (NOISY GROUND) ON TOP
LAYER AND AGND (QUIET GROUND)
ON BOTTOM LAYER. TIE PGND AND
AGND ONLY AT ONE POINT BY DOING
THE FOLLOWING: BRIDGE U1 PGND (PINS 18 AND 19)
AND AGND (PIN 5) TO THE PACKAGE
THERMAL PAD. PUT MULTIPLE VIAS ON THE
THERMAL PAD THAT CONNECTS TO THE
BOTTOM SIDE AGND.
