Preliminary Data Sheet
Ratings and Specifications
Table 8. Absolute Maximum Ratings
The absolute maximum ratings below are stress ratings only. Operation at or beyond these maximum ratings can cause
permanent damage to the device. None of the performance specification contained in this document are guaranteed when
operating at these maximum ratings.

Notes:
1. The analog voltages can be derived from the +1.2V and +2.5V supplies, but must be filtered as shown below before entering the
PPC405EXr. Use a separate filter for each voltage. This circuit can be used for AVDD, AHVDD, SAVDD, and EAVDD

2. The device meets all electrical specifications at a junction temperature, under bias, of 125ºC, but part lifetime and reliability is
reduced. It is recommended that prudent thermal management techniques be used to maximize device lifetime.
