For the output stage datxsheet was no contest, the NJM killed everything else. Here are some of the elite:. Thanks for all that you are doing for the audiophile community, and take care. Several things are important to know about the dScope. I put a JRC in my preamp and used it to drive headphones through 1ohm resistors. I’d love to have Mr AMB step up to a blind test!

Most of this l4580 is written from the perspective of using op amps for headphone and line level audio applications. The gives the best result short of a dedicates headphone driver. But according to your text the OPA should annihilate other OpAmps in a well implemented circuit, then?

For the full schematic, and more details, see the Circuit Description section of the O2 Details Article. If you shift it too far, the distortion goes up. The article was another late night “rush job”.

The output stages are much less critical as unity gain buffers. They’ve been very consistent in every other way as well. Steve Davies January 25, at 2: Kanwar August 19, at 5: Evaluating only by ear, when they hear differences, they’re strongly biased to perceive them as improvements.

Anyone who thinks they know more about op amp applications than the guys designing the op amps is very likely mistaken.

Putting a resistor in the feedback loop actually makes stability worse than no resistor at all. The rest of the time its just unavoidable sighted listening bias–take away the knowledge of which is which and the “differences” disappear. NwAvGuy March 5, at 5: The only concern is the increasing THD with low impedance, which I can’t really datasheft because your graph only graphs 15ohm and ohm, which have a 10x difference; pretty substantial.

Even non-rail-to-rail op amps vary widely in how close they can get to the rails with various loads and operating voltages.

The NJMD is similar to the so it should make a fine buffer. While low power op amps typically have om4580 drive capability, higher noise, lower GBW, and poor slew rate.

Reading through your articles I see you’ve chosen the and the as an opamp and buffer. Pin 7 was connected to a 10K pot yielding datqsheet a 1. This is usually compensated for by adding the correct value of capacitance in parallel with the feedback resistors from output to the negative input. Pardon the Anon status, I’m browsing over a public terminal and the usual cautiousness applies Samuel Groner tested several LT parts with mixed results.

But of course this is a logical fallacy appeal to authority to some extent so I was wondering what you dtaasheet. I think it’s discussed a bit more O2 Details Circuit Description. And the Mini3 is borderline unstable as can be seen with the 4 Mhz ringing in my scope captures.

The TL, on the other hand, is obviously having a hard time as it did in the earlier sweep: Ok, now a question.

This, combined with the inherent matching of transistors made on a single die, and near perfect thermal tracking, provides a bag of tricks no discrete designer can match. But I did test a couple parts from National and Analog Devices.

Would using only one defeat the purpose of a buffer? The total sum of the noise out to 22 Khz is how the — I have heard some versions of the are a few dB better than others.

The reason you don’t want to go smaller with the resistors is differences in DC offset voltage which varies between samples of op datwsheet create a constant DC current between the op amps. Have you considered testing several of the same op amp to see production irregularities?

Yep, I think this article is more my style than the last one.
