Hi,

I use ada4817-1 and adg1414bcpz to convert current to voltage.

But the amplifier self-oscillate at frequency about 80MHz.

How can i cancel the unexpected frequency?

 

In attchment, ADA4817-1 convert current in DUT to voltage. ADG1414BCPZ used to

select feedback resistor to make gain variable.
