Analog Ground. GNDA should be connected directly to the ground plane.
Analog Power Supply. A 3.3V power supply should be connected to
V 3P3A . V 3P3A must be the same voltage as V 3P3SYS .
Digital Ground. GNDD should be connected directly to the ground plane.
Output of the 1.8V Regulator. A 0.1μF bypass capacitor to ground
should be connected to this pin.
System 3.3V Supply. V 3P3SYS should be connected to a 3.3V power
supply.

Differential or Single-Ended Line Current-Sense Inputs. These pins are
voltage inputs to the internal ADC. Typically, these pins are connected
to the outputs of current sensors. Unused pins must be tied to GNDA .
