Ground
Analog Power Supply (1.8 V Nominal).
Digital Output Driver Supply (1.8 V Nominal).
Digital Output Ground.
Analog Ground. Pin 0 is the exposed thermal pad on the bottom of the
package. This is the only ground connection, and it must be soldered to
the PCB analog ground to ensure proper functionality and heat dissipation,
noise, and mechanical strength benefits.
