I’m in the process of selecting an op-amp to act as a voltage follower for the input signal into my data acquisition card.
I'm measuring all types of signals just like an oscilloscope would.
Do I have the slew rate I need correct? I used this calculator and sampling at 1.5 MHz with a peak of 10 V I calculated that I need a slew rate of 94 V/µs.
The reason I ask is I don’t see a lot of choices of rail-to-rail op-amps, through-hole style with that high slew rate.
