content: Edit: you will find download links below.Also, I changed thread title to better reflect its new purpose.I tried to download all application notes ever released by former Linear Technology, but I can't find some of them anywhere. Specifically, it's AN116, AN121, AN127, AN130, AN134, AN150, AN151, AN154, AN156, AN157 and AN163. It seems LT just skipped them, they're not listed on their (archived) website. Do you happen to know why?

content: That's seems unlikely. For example, AN117 was released in April 2008, but AN116 is already missing in May 2008 version of the list:https://web.archive.org/web/20080513170957/http://www.linear.com/designtools/app_notes.jspSome author(s) probably reserved the number, but then couldn't deliver the contents, I guess.

content: I finished a complete Linear Technology application notes collection, you can download it here, it has 150 MB:https://mega.nz/file/EugiwbKC#ZNDjOJaeAABYTUMokX7tFt16RziElOmviGZOpjQdBWQI usedthis xDevs pageas base and then manually filled the gaps. Also, some PDFs were scanned pages without text layer, I performed OCR on those.

content: Thanks for the nice collection, hanakp! I looked in my paper application note collection: both the older Linear Applications Handbooks (which mostly pre-date these particular numbers) and the newer Analog Circuit Design volumes 1 and 2 books (I don't own volume 3), and I didn't see it in any of those. So this and the other evidence in this thread, I think it is most plausible that they were never published for whatever reason.coppercone2: Do you have any evidence to the contrary? A title for the missing app notes, or a publication date, or an author? Or is your assertion purely based on missing numbers while not having any inside knowledge on how and when numbers were allocated?

content: Quote from: hanakp on March 18, 2023, 09:26:55 amAwesome, good job. One problem is that these file hosting links become dead much sooner than desired. They have a single point of failure.I have created a torrent share for it to serve as a backup. If a dozen of people download it and keep seeding it, it'll be much less likely to go missing. Here's a magnet link: magnet:?xt=urn:btih:4080cff8cbdbf983129a6738dc9c9e84132431e8&xt=urn:btmh:1220aad4fd369b49a955d0c38d5b7e0416d319ea3e594631507652d74d78d080e60c&dn=Linear_Technology_app_notes.zip(unfortunately this forum engine can't make them clickable, so you'll have to copy&paste.)Hope it's not illegal. I guess these docs are free to share.

content: Quote from: shapirus on March 18, 2023, 10:40:19 amGood idea! For me at least, it would be more useful to have a torrent of the extracted folder with all PDF files. I'm not very likely to keep a zip file around to seed (in fact I already deleted that file), but an extracted folder of the application notes is something I'm likely to keep around.Another alternative would be uploading them to xdevs.com, or at least the ones that are notthereyet. Seehere for upload instructions.

content: @alm: I could upload them to xDevs, but I changed file numbering scheme so they would be listed in the correct order. Not sure if it's worth the hassle, anyway - about half the notes are about ICs that are obsolete or irrelevant today. I hoard such documents so I can mass-search them while looking for obscure solutions or parts.

content: Quote from: alm on March 18, 2023, 10:44:57 amGood catch.It'll also make it possible to search in file names on torrent search services like btdig.com.Shared as PDFs: magnet:?xt=urn:btih:813ba419e5888b0664fdd0924ddadeac5bb658ab&xt=urn:btmh:1220d345bdf1c297178dd5653ccb154b0be5f42da29cdf1b85dc3987c6c0ab1259ed&dn=Linear%20Technology%20Application%20Notes

content: Quote from: hanakp on March 18, 2023, 12:15:11 pmNevermind the obsolete parts. They often have useful information to learn from, and it can be applied to other parts too.

content: Quote from: hanakp on March 04, 2023, 10:38:55 pmIt’s possible that some of these notes were planned but never published, reserved for internal use, or later merged into other documentation. In some cases, application notes might have been retired or replaced if their content became outdated or irrelevant due to technological advances.
