 		 #115855 - 10uH inductor + 100n
Responding to: ???'s previous message
Dear Kai,

For derving the AVcca and AVref the datasheet uses 10uH inductor and 100nF combination. Do you recommend the same. What kind of inductor should be used I mean is it a soft ferrite like 6 hole ferrite or something else. Can you suggest some RS part nos.

Thanks & Regards,
Prahlad Purohi
