well my requirement is fast. as fast as possible (LM7171 excelent for that) but most importantly very high slew rate and also mil temp range - ill cheack out the opamp tho cheers
I don't know all the specs of the op amps being mentioned, but before you spend some money on them, watch out that you match the op amp with your intended need. Not all "rail-to-rail" op amps are the same. Some of them are r-t-r on the output only and not on the input, meaning that you can drive the output to the rails with a lower input signal and a higher gain, but you may not be able to drive the inputs near the rails in a unity-gain situation without causing some input clamping.
chears all. I'm gonna stick with the LM7171 (its charactersitics are too good for my needs)
I am gonna wrap around the output and the feedback a BJT push-pull stage to up the output current capability. This will give a max output of abt +/-13V so the output of the push-pull will be ~ +/-13V this is to feed a push-pull FET pair and I need to see if the top FET (n-type) will staurate at 13V the Vth is 7V so it should be fine
