Re: Oscillation with AD8137
Uwe, If the input C is 1.8 pF, and you have 1k, then for 10k feedback, you would have 0.18 pF.You could try 1 pF. Put in a step and see how much overshoot you get. Harry

I am sorry that I misunderstood you and was incorrect on your native language. That is what I get for guessing. The time capture buffers are 1024 samples long. Check out page 10 on the ADIS16223...

OK there are two confusions. First I'm french of course.Secondly, if I understand, each capture buffer can containe 1024*16bits. In my mind, 1024 samples = 2^10, whether 10bits. Sorry and thank you,...
