Working Principles
The DS1809Z-050+ is a digital potentiometer that utilizes a combination of resistive elements and electronic switches to adjust the resistance digitally. It consists of two channels, each with its own terminal (A and B) and wiper position controlled by an internal register. The resistance value between terminals A and B can be programmed using the serial interface.
When a specific resistance value is set, the DS1809Z-050+ stores it in non-volatile memory, ensuring that the resistance setting is retained even when power is disconnected. This feature allows for easy reconfiguration of the potentiometer without the need for external components.
