I you're using polyphase sampling you may as well use a svo. The
LT115 is not a good choice - it's phase margin is close to zero and it
is liable to sing at about 25MHz.

Very interesting circuit. Thank you.

Is there a suitable available alternative to LT1115?
OPA1655/56
I have seen LT1115 oscillate at 24 MHz in LTSpice 24.1.1
It doesn't seem to always happen and when it does a little extra load on the output seems to get rid of it.
