Due to the holidays, responses may be delayed. I’ve seen wired things with this though, but satasheet says so in the data sheet, for example, lower offset 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!

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 l3m87n to know, but single lm3877n, dual supply?

The main concern is that the circuit itself should need no changing with the replacement. No license, either express or implied, by estoppel or otherwise, is granted by TI. Mentions Tags More Cancel.

THD at 60dB gain 0. I haven’t seen many designs using it? Most of the typical applications shown on the datasheet can be duplicated with “normal” op-amps, but DC biasing will need to be added.

TI is datasheer global semiconductor design and manufacturing company.

This reduces bias resistor noise contribution, allows easy single supply operation with fewer components, and provides excellent PSRR. However, there must be a DC path between the output and the negative input to maintain DC feedback.

JohnRoberts on September 06, This is an audio circuit. 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 datashee DC biased internally. This thread has been locked. But two 10K resistors and a 47u cap do the same. The LMN has been obsoleted. You may have to modify your existing circuit a bit by adding a blocking cap or a few datasheef resistors to use a “normal” op-amp.

LM is a penny easier because it has a bias voltage built-in, so you can set the output around half-supply. Trademarks Privacy Policy Terms dagasheet Use. Then, always, in “low distortion” audio applications “” because we are not trying to archive 0.

I’m an enthusiast without proper background education in electronics datasehet I’m chewing this slowly. We are glad that we were able to resolve this issue, and will now proceed to close this thread. It also has sad output power. Something similar to what Audiox did with NE If you have further questions related to this thread, you may click “Ask a related datahseet below. Any suggestions would be appreciated.

Do you have another question? The LM has a different pin-out not normally used with dual op-amps – so any board layouts would have to change. 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 datashet ground, so it knows if it has a dual or single rails.

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. Sorry for not replying back after I started this thread.
