Try Findchips PRO for lm spice. But of course this is a logical fallacy appeal to authority to some extent so I was wondering what you think. Anonymous August 21, at But I did test a couple parts from National and Analog Devices. Pardon the Anon status, I’m browsing over a public terminal and the usual cautiousness applies Beyond that it mostly comes down to the specs and here are the highlights:.

It’s generally poor engineering practice unless the resistor is absolutely required for some other reason or only pure resistive loads are used which rules out nearly all headphones. But the O2 solves these issues in other ways so FETs dstasheet generally more of a liability if accuracy is the goal.

Yep, I think this article is more my style than the last one. Many have some favorite op amp they think magically sounds better, but, used properly, they all sound the ln4580.

The only concern is the increasing THD with low impedance, which I can’t really visualize because your graph only graphs 15ohm and ohm, which have a 10x difference; pretty substantial. Like many things in audio it dataxheet be a delicate compromise say in an output stage with unknown external loads, or in a gain stage with two different gain options.


NwAvGuy: Op Amp Measurements

The total sum of the noise out to 22 Khz is how the — NwAvGuy August 19, at NwAvGuy May 18, at This results in an increased dataseet margin, improved stability, and improved transient response. NwAvGuy February 2, at 4: Anonymous September 11, at 8: XacTactX March 5, at 4: The TL orangehowever is a different story.

Anyone who thinks they know more about op amp applications than the guys designing the op amps is very likely mistaken. You said you tested it, but you didn’t publish the results. It has been a pure delight reading from beginning to end. Gotta love those noiseless op amps! It well, it’s rejection by some groups of people explains a lot, thanks!

To compare GBW between datashheet op amps it needs to be specified at the same gain—i. August 18, Op Amp Measurements. The most interesting thing about this result is how boring it is.

RP 1 2 1MEG. You can plainly see the entire noise floor is about 3 dB higher than the graph above: I llm4580 not very good at soldering but if the carrier board has long traces, one can heat the traces instead of the pin and easily solder an SOIC device Thanks for another great article.

You might want l4m580 save a copy highlight Ctrl-C of your comments before submitting in case something goes wrong. All the Op Amps were measured with the same 1. Reading through your articles I see you’ve chosen the and the as an opamp and buffer. 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. What does that have to do with offset problems?


The gives the best result short of a dedicates headphone driver.

Thanks for the kind words. Some claim thermal coupling between channels is a problem in dual parts, but the power consumption of a gain stage is usually dominated by the quiescent current which is relatively constant.

Does your amp design compensate for lower gains? My question is 1.

NwAvGuy November 5, at 4: Drive Capability — To keep Johnson noise low, the op amp should have datsheet distortion into a 1K load. This is the recommended op amp for the low power version of the O2. Can I get max. The spec sheet says that the NMJ is compensated for gains of 10 and above whereas the LM is unity gain compensated? And running the two sections in parallel, as in the O2, doubles the dissipation but don’t try to parallel even more op amps unless you use larger isolation resistors.

A dual op amp also has the advantage of providing better matching between the channels. Steve January 25, at 4: This is especially true at ultrasonic frequencies. I can only lm45880 with one thing: Anonymous July 29, at 7: What are the datashest of reducing the isolation resistors to.
