PRODUCTION DATA.
The exposed pad on bottom of the package is attached to the back of the die to act as a heat sink. Connecting this pad to the PCB ground planes with a low thermal resistance path is the best way to remove heat from the AFE. This pad should also be connected to the ground planes through low impedance path for electrical purposes.
