External links modified[edit]

Hello fellow Wikipedians,

I have just modified one external link on Digital potentiometer. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:

Added archive https://web.archive.org/web/20110907012735/http://www.analog.com:80/en/technical-documentation/frequently-and-rarely-asked-questions/resources/digital-to-analog-converters/digital-potentiometers/listing.html to http://www.analog.com/en/technical-documentation/frequently-and-rarely-asked-questions/resources/digital-to-analog-converters/digital-potentiometers/listing.html

When you have finished reviewing my changes, please set the checked parameter below to true or failed to let others know (documentation at {{Sourcecheck}}).

Citation help[edit]

I was reading this entry and noticed the "Citation needed" tag at the end of the "Design" paragraph regarding the existence of OTP (one time programmable) and programmable digital pots.

Here's a link to a source. Having not the experience nor the inclination to sort through the mess that is the "how to add citation" page, I'm going to leave the link and someone else can add the citation. https://www.maximintegrated.com/en/products/analog/data-converters/digital-potentiometers.html To quote the relevant section:

DIGITAL POTENTIOMETERS Digital potentiometers (digipots) are used to trim and scale analog signals. They provide an output resistance that is variable based on digital inputs and so are sometimes referred to as resistive digital-to-analog converters (RDACs).

Digipots are typically available with linear or logarithmic tap points. In addition, Maxim offers some further variations of the basic digipot. Nonvolatile digipots retain their last programmed wiper position when the power supply is switched off. OTP digpots set the wiper's power-on reset (POR) position to a user-defined value.
