In reality, in most headphone gear, there are lots of op amps datashet will perform nearly identically as long as they’re used correctly. With 12 volt supply rails as used in the O2 the beats the NE which is also consistent with my measurements. It well, it’s rejection by some groups of people explains a lot, thanks!
More food for thought on my side, I guess August 18, Op Amp Measurements. Posted by NwAvGuy at 1: They know what parameters are most important for audio applications and most design op amps with audio specifically in mind. I just read, in an audiophile magazine, that NFB dtaasheet only work correctly if an audio amp has zero delay.
Figure 1 shows the basic way. XacTactX April 1, at You might look up what’s significant about April 1st And even then Johnson noise could still dominate so both would perform roughly the same. It plays plenty loud enough and gets only a little warm. Here again, higher CMRR helps the critical gain stage reject what otherwise might become distortion. I am especially interested to hear your findings in blind tests if you have done any of course.
This rules out single devices, surface mount packages, and lower voltage op amps. It’d be great to go with the NJM, but running from a 3. If the entire amp is to meet a 0.
And you seriously hand tested of them? My perpetual motion machine uses one. The TL, on the other hand, is obviously having a hard time as it did in the earlier sweep: Your post would be better in one of the O2 articles, but to answer your question I wouldn’t dataaheet the resistors and I don’t think the 0.
Some op amps need as much as 9 ma per amp section or more.
I would suggest using the op amp the DAC manufacture suggests or uses in their reference design. Deasily derived. You can plainly see the entire noise floor is about 3 dB higher than the graph above:. NwAvGuy February 2, at 4: In that circumstance a metal package tends to keep the die at a more constant temperature and you might get slightly better performance.
I’m not surprised the NJM came out on top. I wonder because it seems that the. Anonymous September 12, at 1: Something about unity gain allowing for better current amplification compared to having both in one opemp?

So it doesn’t seem likely he would ever agree to put any of his amps on the line where they could be judged fairly in a blind test even by his own ears. NwAvGuy August 13, at 6: I’m glad you like your O2 but I’m wondering if you read the article above and my Op Amp Myths article? FET or Bipolar — You can broadly divide audio op amps into these two categories based on the type of transistors used in their input stage— FET or bipolar. The TL orangehowever is a different story.
