NON Volatile Digital Potentiometers

A digital potentiometer (also called a resistive digital-to-analog converter or informally a digipot) is a digitally-controlled electronic component that mimics the analog functions of a potentiometer. It is often used for trimming and scaling analog signals by microcontrollers.

It Can be divided to Volatile version and Non Volatile version.

Volatile Version will reset when lost power. The non-volatile version can keep the set when lost power.
