Digital Potentiometers(DigiPOT)
Digital Potentiometers, also known as digital pots or digipots, are electronic components that function similarly to traditional analog potentiometers but can be controlled digitally. They consist of resistive elements divided into segments, with a wiper that moves along the resistive track to adjust the output voltage or current. Digital potentiometers are used in various applications for voltage and current adjustments, such as instrumentation, programmable power supplies, and sensor calibration.
The pricing of digipots varies based on several factors such as the resolution, resistance range, interface type, and package type. Higher-resolution digital potentiometers with wider resistance ranges and more advanced communication interfaces tend to be priced higher.
When purchasing the digipots, consider the required resolution and resistance range for your application, as well as the interface compatibility with your microcontroller or digital control system. Evaluate additional features like non-volatile memory to retain settings during power-off, temperature compensation for stable performance across temperature variations, and package type for ease of integration into your PCB design.
