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. Flu got me pretty seriously! But two 10K resistors and a 47u cap do the same. Mentions Tags More Cancel.
Sorry for not replying back after I lm38n this thread. There datqsheet 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? Something similar to what Audiox did with NE We are glad that we were able to resolve this issue, and will now proceed to close this thread.
The main concern is that the circuit itself should need no changing with the replacement. Should I use it? If you have further questions related to this thread, you may click “Ask a related question” below.

I haven’t seen many designs using it? Hi, I started planning a mod on my old datxsheet and I wanted to find an IC opamp that can run on a single supply voltage I never understood quite well the single xatasheet 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.
I want to do a balancing circuit for the direct outs. Is it noisy, frequency impaired or something like that?

Some unbalance at input impedance but nothing to be alarmed for your application, as input device may not be so cool. The LMN has been obsoleted. Nov 24, 8: Then, always, in “low distortion” audio applications “” because we are not trying to archive 0.

However, there must be a DC path between the output and the negative input to maintain DC feedback. Go to Support forums. LM is a penny easier because it has a bias voltage built-in, so you can set the output around half-supply.

Menu Search through millions of questions and answers User. This is an adtasheet circuit. It was an OK part for back then, but I am surprised they still sell them. THD at 60dB gain 0. Nov 27, Most of the typical applications shown on the datasheet can be duplicated with “normal” op-amps, but DC biasing will need to be added.
