1. It is recommended to use the same power supply for VDD and VDDA, the maximum

permissible difference between VDD and VDDA is 300mVduring power up and normal

operation.

2. If TA is low, higher PD values are allowed as long as TJ does not exceed TJmax (See

subsec 5.1).

3. In low power dissipation state, TA can be extended to this range as long as TJ does

not exceed TJmax (See subsec 5.1).
