Front end opamps, which specs matter?

[GT Blocker]

Front and back end op-amps tests so far

Hello all,
So far I'm running the natsemi LME49710 on the front end (BW 55MHz, noise 2.5nv/rtHz, slew 20v/sec) and a natsemi LMP7716 on the back side (BW 17MHz, noise 5.8nv/rtHz, slew 9.5v/sec).

The LMP7716 seemed to solve the problems that I was having with the LMP7702 and its low slew rate, lower BW, and higher noise..

Looks good ATM. Anything I should be looking for empirically (as opposed to it 'seems cool to me')? Thanks, GTB

Somebody should update all the links to the old thunting web site. I think the current link posted by J Player for building fast coils is this one: http://www.geotech1.com/cgi-bin/page...oils/index.dat
