I'm curious if the DC offset of a signal going into an op amp will affect the slew rate. Lets say you have an op amp configured to drive a 150 Ω load and is spec'ed to provided an output swing of ±3 V (say an AD829 or OP27). If I drive the op amp with a signal that has a DC offset of 2.7 V (close but not at the limit of its range) will this affect the slew rate? Here assume that the amplitude of the AC components are stay close or within the ±3 V.
I'm guessing the answer to this question will depend on whether the limiting factor is in the compensation or output driving stage of the op amp. I'm wondering if this is something that is known, that you shouldn't expect an op amp to provide its full slew rate unless its around the center point of its supply range or if it doesn't matter as long as you are within the output swing range.
I guess a good follow up question is whether it matters that you are starting with a DC offset that is positive or negative?
