The application notes listed below are available as pdf files (on the left), as Microsoft Word files (on the right), and selected web pages (listed further down this page).  If you do not use Microsoft Internet Explorer and/or Word, the pdf files are probably your best bet.  We generally do not like the Adobe Acrobat pdf scheme, but it is the best thing going for transferring files between different computing platforms.  The Adobe Acrobat Reader is free and available by clicking the link below (if you are unfamiliar with pdf files, try clicking on an application note first since the reader may already be installed on your machine).  As time permits, more application notes will be made available.

Some of these application notes and other files are also available at the AnaLog FTP Site (anonymous browser access).  Visit ftp.logwell.com if you use a dedicated ftp program.  See the application_notes subdirectory.

AnaLog Services, Inc. also has an extensive library of paper application notes, service notes, schematics, and other technical documents.  While we do try to help folks in need of documents in our collection, we must charge enough to cover our costs.  However, we are always looking for schematics, manuals, etc. not in our library; so if you have something we need, perhaps we can do some horse trading.

Also see our Schematics menu, and see our Printed Circuit Boards (PCBs) page.
