Renesas Electronics Corporation Data Acquisition - Data Acquisition - Digital Potentiometers - X9221AYSI X9221AYSI

The X9221AYSI is a dual digitally controlled potentiometer (XDCP) from Quarktwin Technology Ltd., featuring a 2-wire serial interface for communication. It integrates two potentiometers in a single package, each with 64 taps and a resolution that allows for precise control of wiper positions. The device includes a volatile Wiper Counter Register (WCR) and two non-volatile Data Registers (DR0 and DR1) for storing wiper positions, with the ability to recall settings upon power-up. The X9221AYSI supports resistor values of 2K,Ѷ, 10K,Ѷ, and 50K,Ѷ, making it versatile for various applications such as control, parameter adjustments, and signal processing. It is available in both 20-lead plastic DIP and SOIC packages, providing flexibility in design integration. The device is designed for endurance, with a write capability of up to 100,000 cycles per bit per register. This product is suitable for engineers looking for reliable digital potentiometers with a straightforward interface for their projects.
