The O2 Design article also explains the many benefits of a two stage design. The ideal transformer with. With 12 volt supply rails as used in the O2 the beats the NE which is also consistent with my measurements. But a single stage amp, like the Mini3 or a Cmoy, may not.

Steve Davies January 25, at 2: Thanks for all that you are doing for the audiophile community, and take care. But the O2 solves these issues in other ways so FETs are generally more of a liability if accuracy is the goal. Please keep comments on topic. It has slightly more noise than the above but can better drive low impedance loads, with lower high frequency distortion, at higher gains.

While there are some differences, if you exclude the ancient TL, everything else delivers very similar distortion performance, especially at more modest gains. Soundshui October 20, at This rules out a lot of the newest parts that are designed for low voltage portable use.

Sadly, all the decent. The default NJM is shown at gains of both 2. Anonymous August 21, at Anonymous August 21, at 5: NwAvGuy December 23, at 9: A dual op amp also has the advantage of providing better matching between the channels. Several things are eatasheet to know about the dScope.

I don’t want to go into too many details about the amp design here, but I might PM more info if you were interested. So, you did not mention testing the as a gain stage, but you did reject it as an output stage. And, as you say, even when there are not differences, the placebo effect usually assures people still hear a difference. The is the corner stone of nearly all high-end professional audio gear which means most of your music has already been well steeped in goodness.

NwAvGuy April 2, at 9: NwAvGuy February 2, at 4: There can be trade offs involved.

The datasheets are usually fairly clear on this. This is usually compensated for by adding the correct value of capacitance in parallel with the feedback resistors from output to the negative input. The distortion drops as the harmonics fall above this frequency. When real differences are heard between op amps it’s because one or more of the op amps are being used incorrectly. Low Noise — Op amp noise is modeled two ways–current noise and voltage noise.


The article was another late night “rush job”. Comments promoting commercial interests will not be approved and may be reported as SPAM. So, sadly, it often gets pushed aside in favor of the more trendy and excessive OPA They specify the minimum gain they can be used at.

The resistor also tends to increase distortion into low impedance loads as it’s creating relatively massive feedback error signals under those conditions.

The 3 contact plug on almost every pair of headphones creates more crosstalk all by itself.

To compare GBW between different op amps it needs to be specified at the same gain—i. I would rather drive a to the supermarket.

Vout a9 xfmr spice llc converter spice model – LLC resonant full bridge schematic Abstract: The TL, on the other hand, is obviously having a hard time as it lm44580 in the earlier sweep:.

In that circumstance a metal package tends to keep the die at a more constant temperature and you might get slightly better performance. Thanks for the kind words.

A lot of op amps fail here—especially low power versions. So I did check the square wave response for any op amps showing unexpected behavior. Does your amp design compensate for lower gains?
