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 lm387m not a good thing, I would prefer having all the time the worst case offset datasyeet most applications, at least than this, this implies a huge unlinearity and baaad CMRR!

However, there must be a DC path between the output and the negative input to maintain DC feedback. No license, either express or implied, by datasheett or otherwise, is granted by TI.

LM387N Datasheet

I’m vatasheet enthusiast without proper background education in electronics so I’m chewing this slowly. The LMN has been datssheet. Let’s datahseet the data sheet, if it looks right there it’s time to breadboard. TI, its suppliers and providers of content reserve the right to make corrections, deletions, modifications, enhancements, improvements and other changes to the content and materials, its products, programs and services at any time or to move or discontinue any content, products, programs, or services without notice.


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 dayasheet range which are useful to know, but single supply, dual supply?

Then, always, in “low distortion” audio applications “” because we are not trying to archive 0. 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. 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.

It is made to drive one 10K volume control in the same box, not long wires, multiple loads, etc. Some unbalance at input impedance but nothing to be alarmed for your application, as input device may not be so cool.

Agree that ‘ should be your go-to in this case. Due to the holidays, responses may be delayed. The main concern datqsheet that the circuit itself should need no changing with the replacement.

LMN Datasheet(PDF) – National Semiconductor (TI)

I never understood quite well the single supply thing on opamps, usually ratasheet 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.

THD at 60dB gain 0.

The LM has a different pin-out not normally used with dual op-amps – so any board layouts would have to change. Ask a related question What is a related question? But two 10K resistors and a ddatasheet cap do the same. I want to do a balancing circuit for the direct outs.

This is an audio circuit. Nov 24, 8: If you have further questions related to this thread, you may click “Ask a related question” below. Everything you listen to has been through multiple ‘s.

It also has sad output power. Ask a related question Ask a new question. Something similar to what Audiox did with NE Thanks for your wise replies! LM is a vatasheet easier because it has a bias voltage built-in, so you can set the output around half-supply. I haven’t seen many designs using it?

Mentions Tags More Cancel. Most of the typical applications shown on the datasheet can be duplicated with “normal” op-amps, but DC biasing will need to be added. If I don’t know how it works, I prefer don’t turn it on. It was an OK part for back then, but I am surprised they still sell them.
