Analog ground pin. This is the device’s analog supply ground connection.
It should be connected through a low resistance and low inductance
ground return to the system power supply.
Digital supply input pins. The device operating supply voltage range is
+5V
connected to the same potential. This pin should be bypassed to DGND
with a parallel combination of a 10 µF and a 0.1 µF (ceramic) capacitor.
The capacitors should be placed as close to the supply pins of the part
as possible.
Digital ground pin. This is the device’s digital supply ground connection.
It should be connected through a low resistance and low inductance
ground return to the system power supply.
