1. It is recommended to power V
DD
and V
DDA
from the same source. A maximum difference of 300 mV between V
DD
and
V
DDA
can be tolerated during power-up and normal operation.
2. To sustain a voltage higher than V
DD
+0.3V, the internal pull-up/pull-down resistors must be disabled.
3. If T
A
is lower, higher P
D
values are allowed as long as T
J
does not exceed T
J
max (see Table 19: Thermal characteristics
on page 51).
