Re: Oscillation with AD8137

UweBonnes,

 

  With really high speed op amps, a large feedback resistor with the op amp input capacitance will give you a pole.  Change the 1k/10k resistors to 220/2.2k and see if the frequency of oscillation changes.

 

Where does "SO" go?  It's hard to read your schematic;  is the resistor from "SO" to ground not populated?

The 470 might be too low for the AD8065 to drive depending on where it goes.
