The LMN has been obsoleted. The LM has a different pin-out not normally used with dual op-amps – so any board layouts would have to change. Let’s look the data sheet, if it datashedt right there it’s time to breadboard.

Should I use it? 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 all the time the worst case offset in most applications, at least eatasheet this, this implies a huge unlinearity and baaad CMRR!

Flu got me pretty seriously! We are glad that we were able to resolve this issue, and will now proceed to close this thread. Nov 24, 8: 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. Thanks for your wise replies! Nov 27, The newly created question will be automatically linked to this question.

TI is a global semiconductor design and manufacturing company. Mentions Tags More Cancel. LM is a penny easier because it has a bias voltage built-in, so you can set the output around half-supply. Any suggestions would be appreciated.

It is made to drive one 10K volume control in the same box, not long wires, multiple loads, etc. JohnRoberts on September 06, Most of the typical applications shown on the datasheet can be duplicated with “normal” op-amps, but DC biasing will need to be added.

I’m an enthusiast without proper background education in electronics so I’m chewing this slowly.

Ask a related question Ask a new question. I want to do a balancing circuit for the direct outs.


However, there must be a DC path between the output and the negative input to maintain DC feedback. 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?
