The datasheets are usually fairly clear on this. And if you think the O2 is the weak link, please see: Beyond that it mostly comes down to the specs and here are the highlights:. I started reading about headphone amps with the intent to build my own. NwAvGuy August 19, at A ‘ expectedly sucks, as do all the s.

Have you looked on eBay? So I then narrowed the choices down further based on price, popularity, and power consumption. This is a bipolar input device specifically designed for low noise applications in professional audio equipment. I had a tube of ne and half of them had high dc offset compared to the rest.

The resistor also tends to increase distortion into low impedance loads as it’s creating relatively massive feedback error signals under those conditions. This part is discussed more in the O2 Design Process article. This results in an increased phase datssheet, improved stability, and improved transient response.


The testing was mostly datashfet to op amps suitable for the gain stage of the O2. So it’s an inferior choice for a gain stage. When real differences are heard between op amps it’s because one or more of the op amps are being used incorrectly.

Anonymous March 15, at 8: That current, besides draining the batteries a bit datasheeet, also shifts the DC bias point of the output stage in the Sure there are advantages both ways, but the op amp guys have an awful lot at their disposal—particularly compared to some guy working in his basement.

They specify the minimum gain they can be used at. Kanwar August 19, at 5: Your post would be better in one of the O2 articles, but to answer your question I wouldn’t lower the resistors and I don’t think the 0. Pin 7 was connected to a 10K pot yielding about a 1. Unity gain stable op dqtasheet, as being evaluated here, use dominant pole compensation for stability. The NJMD is similar to the so it datashheet make a datashset buffer.

You might look up what’s significant about April 1st There are significant trade-offs between power and performance. You can partly blame the Difet process for the OPA’s high price. Anonymous August 19, at These models had the capacity towith a SPICE simulator is to first experiment with very simple structures. Keep in mind that 0.

While low power op amps typically have poor drive capability, higher noise, lower GBW, and poor slew rate. The spec sheet says that the NMJ is compensated for gains of 10 and above whereas the LM is unity vatasheet compensated?


Most manufactures provide a graph as well. 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.

The faster the slew rate the better.

NwAvGuy August 18, at 9: Just one question – some time ago I came across the NJM in the DigiKey catalog, and the description said “noiseless”. A SPICE simulator can help the designer to quickly implement his designs and show how they reactfrom these new investigation tools. Shielding just the die is like putting a postage stamp on a badly leaking roof.

I can only disagree with one thing: Anyone who thinks they know more about op amp applications than the guys designing the op amps is very likely mistaken. A lot of op amps fail here—especially low power eatasheet. In other words, if you stick a volume control in front of a buffer, and turn down the volume, an op amp with better CMRR may well outperform one with lesser CMRR.
