Some unbalance at input impedance but nothing to be alarmed for your application, as input device may not be so cool. The LM has a different pin-out not normally daatsheet with dual op-amps – so any board layouts would have to change. Ask a related question What is a related question?

Due to the holidays, responses may be delayed. Let’s look the data sheet, if it looks right there it’s time to breadboard. It also has sad output power.

LM387N replacement OP AMP

Something similar to what Audiox did with NE You may have to modify your existing circuit a bit by adding a blocking cap datxsheet a few bias resistors to use a “normal” op-amp. If you have further questions related to this thread, you may click “Ask a related question” below. Agree that ‘ should be your go-to in this case.


I’ve seen wired things with this though, but nobody says so in the data sheet, for example, lower offset working input voltage daasheet 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! The LMN has been obsoleted. Hi, I started planning a mod on my old console and I wanted to find an IC opamp that can run on a single supply voltage Ask a new question Ask a new question Cancel.

LM387N Datasheet

We are glad that we were able to resolve this issue, and will now proceed to close this thread. I would suggest using something more l,387n, this part was designed to operate at high gain not stable below 10x with small input voltages, and nominal input voltage DC biased internally. 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.

It is made to drive one 10K volume control in the same box, not long wires, multiple loads, etc. Thanks for your wise replies! LM is a penny easier because it has a bias voltage built-in, so you can set the output around half-supply. Ask a related question Ask a new question.

I’m an enthusiast without proper background education in electronics so I’m chewing this slowly. There are other datasjeet 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?
