1. Functional and tested operating conditions are given in Table 3-2. Recommended Operating Conditions on page 18. Absolute
maximum ratings are stress ratings only, and functional operation at the maximums is not guaranteed. Stresses beyond those
listed above may affect device reliability or cause permanent damage to the device.
2. This is an implied DC voltage specification. Pending further evaluation, an allowance for AC overshoot or undershoot may be
accommodated beyond this input voltage specification.
3. Power supply ramping recommendations:
The order does not matter as long as the supplies reach their final destination in 50ms.
V
can not exceed OV by more than 0.8V (Except for 50ms during power up/down, where it is allowed to be ≤ 1.35V).

DD
OV can not exceed V by more than 0.8V (Except for 50ms during power up/down, where it is allowed to be ≤ 1.55V).
AV can not exceed V by more than 2.5V (Except for 50ms during power up/down, where it is allowed to be ≤ 2.75V).
