P2020 AVDD current requirements.

Hello,

I am looking for the P2020 AVDD current requirements. AN4261 says to use 5 Ohm 0402 resistors in the RC filters for most of them, so the current must be small, but I could use specific values. 

Thanks,

Todd

Have a great day,

In steady state all AVDDs except AVDD_SRDS consume about 5 mA each.

AVDD_SRDS consumes about 30 mA.

Thank you Serguei.

Is this type of information available somewhere, or do I need to keep coming back to the community here?  For instance, now I am looking to see if there is any appreciable current on the MDIC pins.  We have the 18.2 Ohm resistors in there to set full strength, but I need to figure out current through the resistors to calculate strain/margin.  I assume it is small, but can't be sure.

Best Regards,

Todd
