Hi all....
I'm putting together a little circuit this weekend based around the AD725 NTSC encoder IC for a class I have on monday. I am designing the analog power/ground to digital power/ground part of the board, and the reference design I am using has some parallel capacitors in series with a ferrite bead between the power to the analog and digital parts of the circuit. I don't have any ferrites, but there is a drawer on the lab bench labelled "choke coils" with values from 1.2uH to 1000uH...can I substitute one of these for the ferrite? The smaller the better, right?
Thanks!
