I'm not sure how much elaboration is needed, but here's some:
If you take all of the feedback from the output terminal, that's
better for DC accuracy by eliminating the voltage drop of the series
resistor, while still providing some overload protection to the
opamp. But, it also decreases phas
Hi Ed,
I am a little confused with regard to your paragraphs 3 & 4. Could you
elaborate
on those two paragraphs ?
thank you,

The simplest way to drop the output impedance without adding much
circuitry is to just change the series R to 100 ohms or so - that
would still give pretty good isolation from capacitive loading.
If the R is dropped to zero, the DC performance will be best, but
you'll have to worry about the a
