That’s what happens ,m4580 people who don’t fully understand the engineering start messing with parts that have response out into the tens or hundreds of Megahertz. I just read, satasheet an audiophile magazine, that NFB can only work correctly if an audio amp has zero delay.

That creates unwelcome phase shift in the feedback signal. The most interesting thing about this result is how boring it is. My point was I’ve not seen any evidence, even in a mass produced product using the NJM, that it’s a problem. For the gain stage the final list worked out to:.

FLAudioGuy November 5, at 2: Anonymous October 9, at 1: The O2 is a low impedance application and the current noise will likely dominate but both have to be considered along with the Johnson noise. Most manufactures provide a graph as well. Enclosing short circuit protection in the feedback loop, as datawheet in the AMB Mini3, can create stability issues and increase distortion.


The TL, on the other hand, is obviously having daatsheet hard time as it did in the earlier sweep: Meares and Charles E. Can I get max.

It performs notably worse in every way than NJM except power consumption. I should satasheet clarify that in my article. I had a tube of ne and half of them had high dc offset compared to the rest. It has very little to do with better real world performance or a genuine difference in sound quality. The resistor also tends to increase dqtasheet into low impedance loads as it’s creating relatively massive feedback error signals under those conditions.

Most of this article is written from the perspective of using op amps for headphone and line level audio applications. The dissipation goes up with the square of the supply voltage. Comments promoting commercial interests will not be approved and may be reported as SPAM.

Anon, I don’t know anything about the NE, which as far as I know, dagasheet even available. The industry rule of thumb, even on the recording side of the signal chain, is 0.

Removing op amp part numbers creates “mystique”, makes it harder for someone to clone your design and sell it on eBay, and may be to hide using inexpensive parts.

But the new fast part is unhappy in a PC board and circuit designed for a much slower part. Will you be able to talk a little more about the alternative buffer opamps? A ‘ expectedly sucks, as do all the s.

Sadly, all the decent. The professional audio favorite, the NE, is about 3 dB worse at 7X gain than the less expensive and less current hungry NJM above but still very quiet.

Anonymous June 10, at 3: Overall I tested nearly two datzsheet op amps. Here are the favorites plotted vs frequency also taking the output directly from the gain stage op amp under test. I’m not surprised the NJM came out on top. A SPICE simulator can help the designer to quickly implement his designs and show how they reactfrom these new investigation tools.

I did lots of tests with different samples of the and different value resistors to arrive at the optimal 1 ohm value. I’d love to have Mr AMB step up to a blind test! The datasheets are usually fairly clear on this. A lot of people using op amps to drive headphones are operating them well outside their design criteria. Of course even if you measured everything else under the sun they’d still tell you either that something else mystical and unmeasurable was causing the differences they can only hear sighted or that the high-speed opamp they put in a circuit that makes it unstable is more actually “musical”.
