Hi All,
I realize that using a single-supply op-amp as a buffer may be one
of the easiest circuit configurations in the world; just tie the
chip's output back to the inverting input, and insert the signal into
its non-inverting input. That's how the books show it anyway, but
are their any real-life op-amp issues that I have to look out for with
this basic circuit? Anything I can do to make this circuit operate
better under temperature, along with the unavoidable op-amp variations?
Perhaps to help with any stability or voltage offset issues? Or is
this circuit simply the way op-amp buffers are done, even in real life?
Thank You,
Bill
