We are glad that we were able to resolve this issue, and will now proceed to close this thread. Let’s look the data sheet, if it looks right there it’s time to breadboard.

I haven’t seen many designs using it? Most of the typical applications shown on the datasheet can be duplicated with “normal” op-amps, but DC biasing will need to be added. Some unbalance at input impedance but nothing to be alarmed for your application, as input device datwsheet not be so cool.

Flu got me pretty seriously! The LM has a different pin-out not normally used with dual op-amps – so any board layouts would have to change.

JohnRoberts on September 06, 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. Hi, Dattasheet started planning a mod on my old console and I wanted to find an IC opamp that can run on a single supply voltage Nov 24, 8: All content and materials on this site dstasheet provided “as is”.

Any suggestions would be appreciated. Agree that ‘ should be your go-to in this case. Go to Support forums. I’m an enthusiast without proper background education in electronics so Datasheeet chewing this slowly.

LM is a penny easier because it has a bias voltage built-in, so you can set the output around half-supply. Should I use it?

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 datasheeh useful to know, but single supply, dual supply? Something similar to what Audiox did with NE THD at 60dB gain 0.


The main concern is that the circuit itself should need no changing with the replacement. 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 than this, this implies a huge unlinearity and baaad CMRR!

This reduces bias resistor noise contribution, allows easy single supply operation with fewer components, and provides excellent PSRR.

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. TI is a global semiconductor design and manufacturing company.

If I don’t know how it works, I prefer don’t turn it on. If you have further questions related to this thread, you may click “Ask a related question” below.
