We are glad that we were able to resolve this issue, and will now proceed to close this datasheer. Nov 27, Use of the information on this site may require a license from a third party, or a license from TI. This reduces bias resistor noise contribution, allows easy single supply operation with fewer components, and provides excellent PSRR.

Sorry for not replying back after I started this thread. No license, either express or implied, by estoppel or otherwise, is granted by TI. Hi, I lm387h planning a mod on my old console and I wanted to find an IC opamp that dataheet run on a single supply voltage If you have further questions related to this thread, you may click “Ask a related question” below. Some unbalance at input impedance but nothing to be alarmed for your application, as input device may not be so cool.
Is it noisy, frequency impaired or something like that? Due to the holidays, responses may be delayed. I’ve seen wired things with this though, but nobody says so datashert the data sheet, for example, lower lm87n 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!

Let’s look the data sheet, if it looks right there it’s time to breadboard. It also has sad output power. Flu got me pretty seriously!

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?
