|Elliott Sound Products||Application Note Index|
Page Last Updated - 10 January 2017
These application notes are presented as a means of making useful circuits and sub-circuits available, along with some information about how they work, test results (where applicable), etc. Some of these are adapted from the projects page, as their application has the potential to be broader than indicated in the project itself.
Few of these (already published or yet to be published) are original, although some have been adapted and changed to the extent that the original may barely be recognisable. As always, if you have a good circuit idea feel free to submit it (along with any reference material).

Each application note may have one or more 'flags'. These indicate the status of the app. note, and are as follows ...
|The design (or update) is less than 2 months old (or thereabouts)|
|Mains wiring is involved, and is potentially dangerous - heed all warnings ! Note that other app. notes may also need a power supply which also requires mains wiring|
|Date||The page was added or updated on the date shown|
|The appnote has had an update since original publication|

ESP reserves the right to change or update application notes, projects and articles without notice, so it is important to be aware that a change may have been made. You should always watch for updates of previously published items. Do not build any of the circuits presented here without checking for updates first. An "update" symbol indicates an addition or update within the last two months or so.
Please see the ESP disclaimer for important information about this site and the contents thereof.
Please note that these application notes are not supported, so do not ask for assistance or explanations. All circuits are checked for accuracy, but it is not guaranteed that they will work for your application. In the same way that you might find application notes published by semiconductor (or other) manufacturers, you don't e-mail them for help and the same applies here.
Submissions are welcome, but unlike magazines where they may offer prizes or cash for submissions, all I can offer is wide distribution of your idea. Please ensure that any submission is accompanied by full disclosure of references - do not try to claim the work of others as your own.
