I would rather drive a to the supermarket. Slew Rate — All were over the 2. Those are all dinosaurs from the era before fast power transistors were available for high power amps. Lm4508 can be trade offs involved.

Any of those can make it sound different.

Can I get max. My main reason for choosing the and were for the much lower current usage. Quiescent Current — In a battery powered device the quiescent idle current is a critical spec.

August 18, Op Amp Measurements.

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 most popular are these op amps which have found their way into a lot of high-end audiophile blessed gear.

The output datazheet are much less critical as unity gain buffers. Don’t worry about your detractors a bit. NwAvGuy August 18, at 9: You might look up what’s significant about April 1st 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. If I were to design an amp around these, would it be necessary to use two s for output buffering?

In fact, it may degrade the performance because the O2’s transient response compensation has been optimized for the NJM And even then Johnson noise could still dominate so both would perform roughly the same. And that’s all that separates an amplifier from an oscillator.

If the op amp’s key parameters fluctuate significantly with temperature om4580 you can get some degradation in the performance from thermal modulation. NwAvGuy June 11, at 1: Have you considered testing several of the same op amp to see production irregularities? I’d love to have Mr AMB step up to a blind test!

I’m glad you like your O2 but I’m wondering if you read the article above and my Op Amp Myths article?

In a Cmoy, or other application, where the op amp lm5480 driving headphones directly nearly all of them are working under stressful conditions. NwAvGuy September 11, at 9: The sound was unbelievably transparent maybe that should be believably transparent.


But a single stage amp, like the Mini3 or a Cmoy, may not. Also note the noise floor is well below — dB except close to 20 hz which is actually an artifact.

So for cost savings, and to save board space, the choice is obvious—use a dual op amp. If lm450 entire amp is to meet a 0. Anonymous August 21, at 5: This results in an increased phase margin, improved stability, and improved transient response. But, op amps have become so good they can easily approach or even better that. There’s a section in the O2 Details article Circuit Description that talks about power dissipation.

Please keep comments on topic. Even if you use the much more stringent —80 dB threshold of 0. Yes, I just happen to have these two Op Amps in front of me. For example lm5480 third harmonic of 8 Khz is 24 Khz and would be rejected by the analyzer.
