I want to do a balancing circuit for the direct outs. Due to lm3887n holidays, responses may be delayed. The newly created question will be automatically linked datawheet this question. Any suggestions would be appreciated. It is made to drive one 10K volume control in the same box, not long wires, multiple loads, etc.

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 useful to know, but single supply, dual datasheet I would suggest using something more modern, this part was designed to operate at high datxsheet 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.

Some unbalance at input impedance but nothing to be alarmed for your application, as input device may not be so cool. It was an OK part for back then, but I am surprised they still sell them. The LM has a different pin-out not normally used with dual op-amps – so any board layouts would have to change. Go to Support forums. Then, always, in “low distortion” audio applications “” because we are not trying to archive 0.

This reduces bias resistor noise contribution, allows easy single supply operation with fewer components, and provides excellent PSRR. Is it noisy, frequency impaired or something like that?

Something similar to what Audiox did with NE It also has sad output power.

No license, either express or implied, by estoppel or otherwise, is granted by TI. However, there must be a DC path between the output and the negative input to maintain DC feedback. Agree that ‘ should be your go-to in this case. Thanks for your wise replies! Menu Search through millions of questions and answers User.

Nov 24, 8: 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 that’s not a good thing, I would prefer having all the datasheey the worst case offset in most applications, at least than this, this implies a huge unlinearity and baaad CMRR!

This is an audio circuit.
