Ground pin
Deciding the reference current for the differential pairs.
The pin was connected to the precision resistor tied to
ground to decide the appropriate current; 475 ohm is
the standard value.
Power good is a low active input signal used to
determine when FS [4:0] are valid to be sample.
Power Down Function. This is power down pin, high
active (PD).
