Hi Frank and Thanks for your information

I attached my schematic here to see if I did ok with these VCCA pins or not

actually for every VCCA pin I have two couple capacitors .1uF and 220pF. and for issolating analog power and ground I have two ferriet beads between and I have seperate ground islands.

i am not sure that the way I used the ferriet bead for VCCA and 1.2V is ok or I need to change it

I'm wondering if you can let me know

thanks

Regards
