Dataaheet look the data sheet, if it looks right there it’s time to breadboard. Sorry for not replying back after I started this thread.

There are other things that usually are associated with it which is good to appear on the data sheet, for example input beyond the rails or rail to rail output, or one rail inside or close to the output range which are useful to know, but single supply, dual supply?
It is made to drive one 10K volume control in the same box, not long wires, multiple loads, etc. Most of the typical applications shown on the datasheet can be duplicated with “normal” op-amps, but DC biasing will need to be added.

JohnRoberts on September 06, The main concern is that the circuit itself should need no changing with the replacement. If you have a related question, please click the ” Ask a related question ” button in the top right corner. Should I use it? Thanks for your wise replies!
No license, either express or implied, by estoppel or otherwise, is granted by TI. I never understood quite well the single supply thing on opamps, usually your opamps don’t refer anything to ground, I mean, there isn’t any pin from it connected to ground, so it knows if it has a dual or single rails.

Do you have another question? The LM has a different pin-out not normally used with dual op-amps – dafasheet any board layouts would have to change.
You may have to modify your existing circuit a bit by adding a blocking cap or a few bias resistors to use a “normal” op-amp.
I’ve seen wired things with this though, but nobody says so in the data sheet, for example, lower offset working input voltage close to lower rail than at the mid point, but that’s not a good thing, I would prefer having datasheeet the time the worst case offset in most applications, at least than this, this implies a huge unlinearity and baaad CMRR!
If I don’t know how it works, I prefer don’t turn it on.
