ABSOLUTE MAXIMUM RATINGS
All requirements applicable to each pin must be met. Where
multiple limits apply to a pin each one must be met individually.
The limits apply according to the functionality of the pins at the
time. Pins that can be either analog or digital, that is, that have
two types indicated in the pin descriptions, must meet the limits
for both types. For pin types, see Table 10.
When powered up, all ground pins and ADC_REFN must be
connected together to a node referred to as GND in Table 9.
The limits that are listed must be reduced by any difference
between any GNDx pin. Also, AV DD3 must be connected to
AVDD4 and IOVDD1 must be connected to IOVDD3.

Note that this pin is always in MDIO mode.
2
This limit does not apply if no current can be drawn by external circuits on
IOVDDx because, in this case, IOV
DD
follows to a suitable level.
3
This limit does not apply if no current can be drawn by external circuits on
AVDDx because, in this case, AV
DD
follows to a suitable level.
Stresses at or above those listed under Absolute Maximum
Ratings may cause permanent damage to the product. This is a
stress rating only; functional operation of the product at these
or any other conditions above those indicated in the operational
section of this specification is not implied. Operation beyond
the maximum operating conditions for extended periods may
affect product reliability.
