Wednesdays can’t come fast enough! Used in high gain critical applications the rules can be different. Bruno Putzeys a truly brilliant guyin particular, has put most of the remaining persistent myths to their overdue death. NwAvGuy November 5, at 4: A sine wave at those frequencies typically creates even greater thermal swings than most music does.

This is usually compensated for by adding the correct value of capacitance in parallel with the feedback resistors from output to the negative input. RP 1 2 1MEG.

Anyone who argues the specs don’t matter is welcome datasheer step up and take the challenge with their own ears, their own headphones, and their own music. Anonymous August 20, at 4: The gives the best result short of a dedicates headphone driver. I am building several for friends and family and look forward to “un-hearing” them, lol.

Try Findchips PRO for lm spice. Unfortunately, as you mentioned, these sorts of ideas never rest in peace no matter how datahseet evidence stacks up against them. The dScope reads as low as 0. Otherwise, stick with Unity Gain Stable compensated op amps.

But a single stage amp, like the Mini3 or a Cmoy, may not. Newer Post Older Post Home. But I did test a couple parts from National and Analog Devices.

While there are some differences, if you exclude the ancient TL, everything else delivers very similar distortion performance, especially at more modest gains.

Steve Davies January 31, at 3: Furthermore, the paper analyzes the influence of thewhen we talked about reluctance: It may take several seconds. While I did adjust the compensation and feedback impedance with some op amps, ultimately, the measurements are all in the same circuit configuration unless otherwise noted. Would using only one defeat the purpose of a buffer?

Unique Advantages — For those who prefer discrete designs over op amps, I refer you to Q9 in the small snippet to the above right. This rules out single devices, surface mount packages, and lower voltage op amps. It does, however, have vastly better low impedance drive capability which might be useful in some rare applications. In fact, it may degrade the performance because the O2’s transient response compensation has been optimized for the NJM Single or Dual — The crosstalk between sections of dual op amps designed for audio use is typically better than — dB.

But this game is all about bragging rights. Something about unity gain allowing for better current amplification compared to having both in one opemp? They have no way to test they got it right. Thanks for the kind words. So most of my evaluation was limited to what Mouser stocks. Those are all dinosaurs from the era before fast power transistors were available for high power amps.

There’s the RFI issue as a very weak possibility. I have heard some versions of the are a few dB better than others. The most interesting thing about this result is how boring it is. Vout datashheet xfmr spice llc converter spice model – LLC resonant full bridge schematic Abstract: Slew Rate — All were over the 2.

I started reading about headphone amps with the intent to build my own. Drive Capability — To keep Johnson noise low, the op amp should have low distortion into a 1K load. This is especially true at ultrasonic frequencies.

Here the dScope bandwidth extends to 44 Khz testing the older V1. Phase — This is set by the dqtasheet feedback compensation capacitor to less than 1 degree error at 10 Khz with all the op amps. Steve Davies January 25, at 2: If I were to design an amp around these, would it be necessary to use two s for output buffering? A lot of the people you’d argue satasheet this sort of thing with will tell you that THD is a worthless spec anyway.

NwAvGuy September 11, at 9: The only theory I’ve heard to explain this is that the metal can package rejects RFI better. The LM and its siblings, in any headphone or Datashet application I can imagine, should match any of the elite parts above. Anonymous July 29, at 7:
