The best audio op amps are around dB typical and it can make a big difference in the performance—especially at higher gains. I’m curious though, is this possibly why ‘companies’ like RSA file away the OpAmp markings on their products.

The resistor also tends to increase distortion into low impedance loads as it’s creating relatively massive feedback error signals under those conditions. I’m not saying their units sound datasheey better than any number of other DACs that measure well beyond the “it matters” point, but their heroic engineering ddatasheet Swiss precision are worth the price in the same sense that a Patek justifies a premium over a Rolex.

Putting a resistor in the feedback loop actually makes stability worse than no resistor at all.

And a lot of audiophile designs have poor PSRR as they use discrete circuits or op amps not designed for audio. Evaluating only by ear, when they hear differences, they’re strongly biased to perceive them as improvements.

With 12 volt supply rails as used in the O2 the beats the NE which is also consistent with my measurements. If the op amp’s key parameters fluctuate significantly with temperature changes lm458 can get some degradation in the performance from thermal modulation. But, somehow against all those supposed audiophile gurus, the speed is rock steady and the feedback works perfectly.

I’ve also seen examples of where someone removes a relatively slow op amp from a piece of gear and replaces it with a much faster op amp thinking it’s an upgrade.

XacTactX April 1, at NwAvGuy September 11, at 9: NwAvGuy August 18, at 9: A SPICE simulator can help the designer to quickly implement his designs and show how they react lmm4580, from these new investigation tools. It plays plenty loud enough and gets only a little warm. I would rather drive a to the supermarket. But if you simply use op amps with excellent PSRR, any variations on the power supply end up well below the noise floor of the entire design even datassheet an inexpensive power supply.

Such a signal would never make it through the recording chain, and if it did, would fry tweeters and cause bats to fly into the side of your house.

Ideally look for a THD graph at 2K or less with some gain. Is it a clear upgrade in every category, or is it better in some things and worse dafasheet others? SPICE model from the ground-up for simulation is esoteric and often time consuming.

But the new fast part is unhappy in a PC board and circuit designed for a much slower part. So the O2, worst case, needs to slew 20 volts in 22 uS or a slew rate of 0. Vout a9 xfmr spice llc converter spice model. The dScope reads as low dagasheet 0. Unless you have your O2 configured for freakishly high gain, the output op amps dominate the distortion in the amplifier.

Soundshui October 20, at Furthermore, the paper analyzes the influence of thewhen we talked about reluctance: NwAvGuy November 5, at 4: Comments promoting commercial interests will not be approved and may be reported as SPAM.

Meares and Charles E. Anonymous August 21, at Plus the O2 uses a separate device for each channel which not only doubles the output dissipation lowering the temperature of each device but also prevents one channel from thermally modulating the performance of the other. Does your amp design datssheet for lower gains? Using a more expensive op amp in the gain stage won’t help anything. I should probably clarify that in my article. And apparently heycarnut is willing to raise the prize money even further.

So for cost savings, and to save board space, the choice is obvious—use a dual op amp. The OPA needs only 0.

Steve January 25, at 4: Shielding just the die is like putting a postage stamp on a badly leaking roof. When price matters, you can get amazingly good performance if you know where to shop. Low Noise — Op amp noise is modeled two ways–current noise and voltage noise. Yep, I think this article is more my style than darasheet last one.

Samuel Groner tested several LT parts with mixed results. A sine wave at those frequencies typically creates even greater thermal swings than most music does. So, to summarize, if you’re using an op amp within its design criteria, and it’s designed for high performance audio use, and especially if you’re not sharing channels within an op amp, it’s unlikely the package will make any measurable or audible difference.
