Digital Potentiometers

What is a Digital potentiometers?
A Digital potentiometer, similar to a standard analogue potentiometer but instead uses digital signals and switches to perform actions, not mechanical.
Where might I use one?
They are used for many variety of functions, including volume control application or any other application that require analogue signal control.
Features and benefits:
• Several control interfaces available
• Varying resistance values
• Easy to mount
• Multiple pin counts
• Dual or single power supply types
Where might I use one?
• Measuring variables/parameters in a circuit
• Control of voltage or current/resistance
• Any mixed signal electronic product is compatible with digital potentiometers
