Working Principle

The AD5251BRU10 is an 8-bit nonvolatile memory digital potentiometer that has 16kΩ resolution. It consists of two 16kΩ end-to-end resistive elements and is programmed by setting wiper tap points along the resistor ladder. Each wiper tap point has 8-bits of resolution, which is transferred to one or the other side of the resistor ladder by the address select lines. Because the device is nonvolatile, it can store the position of the wiper tap point, even when power is removed. The AD5251BRU10 can be interfaced to most popular microprocessor buses and digital logic, making it easy to implement into a wide range of systems.

Conclusion

The AD5251BRU10 Digital Potentiometer is a powerful and versatile device suitable for a wide range of data acquisition applications. It is a low-power device, making it suitable for operations with tight power constraints and its nonvolatile memory allows for the wiring tap point to remain set even when power is removed. The AD5251BRU10 supports many popular microprocessor and logic buses, making it easy to incorporate into existing systems. It is an ideal solution for data acquisition and for controlling analog signals for industrial applications.
