But two 10K resistors and a 47u cap do the same. Go to Support forums. Thanks for your wise replies!

Something similar to what Audiox did with NE All content and materials on this site are provided “as is”. Some unbalance at input impedance but nothing to be alarmed for your application, as input device may not be so cool.
Is it noisy, datashret impaired or something like that?
This is an audio circuit. Hi, I started planning a mod on my lm37n console and I wanted to find an IC opamp that can run on a single supply voltage It was an OK part for back then, but I am surprised they still sell them.

I’m an enthusiast without proper background education in electronics so I’m chewing this slowly. Sorry for not replying back after I started this thread. The LMN has been obsoleted. JohnRoberts on September 06, I would suggest using something more modern, this part was designed to operate at high gain not stable below 10x with small input voltages, and nominal input voltage DC biased internally.

Should I use it? 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 datashret connected to ground, km387n it knows if it has a dual or single rails.

LM is a penny easier because it has a bias voltage built-in, so you can set the output around half-supply. If you have a related question, please click the ” Ask a related question ” button in the top right corner.

Let’s look the data sheet, if it looks right there it’s time to breadboard. I’ve seen wired things with this though, datashert nobody says so in the data sheet, for example, lower offset working input datasneet 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!
I haven’t seen many designs using it? However, there must be a DC path between the output and the negative ,m387n to maintain DC feedback. It also has sad output power. Ask a related question What is a related question?
