I have attched here piece of a working circuit.I just dropped in TL3016 in place of AD8561 confident that it will replace seamlessly.
To my surprise, TL 3016 in the circuit took longer time for output. About 700 ns.
I am also attaching the LTspice simulation with TL3016 in place of LT1016. You can see the output of TL3016 and AD8561 both in the image. TL3016 shows sharper and faster repsonses in LTspice circuit for LT1016.
Can anybody here point out what connection may not be to TL3016 liking in the circuit ?
Thanks all in advance,
