Hello,
By checking the LM318 specs, auxiliary circuits page 10, besides the offset adjust solution which is quite common, I see also the possibility to balance for increased slew rate. Because of some influencing, is it realistic/workable to combine these two solutions on one OpAmp? Thanks in advance.
Morning Willem,
I suppose you are talking about this figure.
1. The offset adjust is in the input stage - a DC balancing, but it does not improve drift
2. The slewing feedforward seems pretty crude, inverting only and probably injecting signal into the comp.node if the error voltage shows a transient to couple through -not going to improve settling time with that AC coupled path.
You can use both in one design, but why you would be looking at this when there are so many much better improved devices is a mystery.
Well, to screen down to current solutions, your design requirements would be useful.
Keep in mind if the LF357 is gone, how far can the LM318 be behind it. Here is a quick x-ref search, not necessarily what you want, as your requirements are not yet detailed.
