Ratings and Specifications
Table 7. 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
PPC405EX. Use a separate filter for each voltage. This circuit can be used for AVDD, AHVDD , SAVDD, and EAVDD. Use AGND
with AVDD and AHVDD. Use SAGND with SAVDD. Use EAGND with EAVDD. These analog grounds must be brought out and
connected to the digital ground plane at the filter capacitor. Keep all wire lengths as short as possible.

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.
