EEVblog #600 - Opamps Explained

[Rigby]

IMHO, don't make it optional.  Provide the torrent file on you website and not the video file.  Those that want the video will use the torrent to get it.

So I should ignore several thousand people who want the RSS feed and force them to either go without or use torrent?
I might as well stop the podcast version entirely and force people to download from youtube, that saves me a step and the hassle.

torrent clients can automatically load .torrent files from RSS.  It's a useful thing.

will you do a video about electronics math

On the subject of using operational amplifiers as comparators, I ran across a PMI (Precision Monolithics Incorporated) application note discussing this very thing.  Most people will not remember PMI but they designed minor parts like the OP-07 series.

Here is a link to PMI's  Linear and Conversion Applications Handbook published in 1986 which discusses this on PDF page 119 which is PMI application note 25, Applying the OP-06 Op Amp as a High Precision Comparator.

I apologize.  I did not know that people where getting the videos via the RSS feed.

and iTunes as well, which sucks the video form the RSS feed. Youtube hosting and torrent hosting don't work for this.

We discussed something like this over on the Yahoo Tektronix and other lists in connection with moving to a new host after the recent Yahoo fiasco and my conclusion was that the web and email accessible forum should work with a torrent tracker to index and provide updated torrent links to downloadable content which would be preferred simply to help manage bandwidth.  Of course such a system is more complex but at least it should fail gracefully.

The largest problem other than complexity is the one you identified; bittorrent is not the lowest common denominator and only a minority of users are setup to handle it.

Crossover distortion was interesting for me, and I'd appreciate another video on ways that op-amps are non-ideal (aside from the bias current and offset voltage topics you've already covered.)

[sergey]

Yeah, crossover distortion was totally interesting. But i thought there'll be some feedback about summers here as well. Not as if i don't know how it works, but seeing more guys having an enlightenment on this is always really nice, hope you see what i mean Or maybe there're some folks who still scratches their heads and wants an urgent help

P.S. Application of the summer is also interesting to look into

[David Hess]

My favorite example circuit for operational amplifiers is the differentiator because it teaches how to generate and use bode plots to establish stability.

Is there any chance you'll make the videos available for download from a server a bit better than a 286 on a dial-up modem? Download times that exceed 45 min regularly fail and have to be restarted. Some of us pay for internet access and wasting it is not an option.

How about it?

Install many other browser plugins for video downloading and you can save the videos for watching off-line with no issues.  You can also specify the video quality to trade off quality for size.

I do this with YouTube videos routinely with a Firefox plug-in although that limits the maximum resolution to 720p now.

Just for the record for those who are not subscribed to w2aew's channel, he just uploaded opamp summing amplifier video . Really great video as well i'd say. Thanks man!

Thanks for the plug, Sergey!

That is a really good video, even better than Dave.

Thanks, but I wouldn't go THAT far!  Dave's videos are still among those that set the standard by which other are judged, IMHO.

Well, it's a bit unfair to compare you guys in better/worse terms, it's just different styles! And this is really nice to have it different, really. So just keep doing awesome stuff in your own way

[Rigby]

multiple styles are good.  this is the thing about teaching and learning that many forget... no two people learn best in the same exact way.  everyone has a history that contributes to the way they learn most effectively.  There is no single learning or teaching type that works for everyone.

The more videos on youtube about X from different authors, the better.

[Alexei.Polkhanov]

Every time I try to design any practical circuit for signal conditioning for photodiodes, piezoelectric pressure sensors or current sensor I always had to choose between different types of opamps like JFET input voltage-feedback amplifiers, or Current-feedback amplifiers (like AD8001 - how do I make it not to oscillate like crazy?), differential opamps, transimpedance opamps or instrumentation opamps and so on.  Maybe it just me because I always measure things? 

I think there is definitely a lack of good introduction videos on practical applications of DIFFERENT TYPES of opamps. I would love to see second part of video that covers some of that.
