AD8210

Hello,

We are using AD8210 for high side current sensing at   bidirectional dc-dc converter. We have two problems about it. First we   have used 470 pF instead of 400 pF mentioned in the document:   (http://www.analog.com/static/imported-files/application_notes/120739192AN815_0.pdf)   But we saw unexpected high gain. What should be the reason?

Secondly  we saw harmonic on the output signal and we know it is  because of  switching of converter. We use the converter at 20 kHz. Can  we use  input filtering to get rid of these harmonics? If we can use waht   should be the Cfilter? (We have used 10 ohm as Rfilter)

Best regards...
