PVDDAMP power supply ramp-up slope (Note 1, 3)

1.5

V/ms

Notes:

1. Power supply ramp-up slope recommended values take into account the recommended

decoupling networks to be used on each supply rail, as well as output current capability of

power supplies typically used in smart metering applications.

2. The VDDAMP pins connected at the PCB level.

3. The PVDDAMP pins connected at the PCB level.
