The X9221WS is a Quad 256-tap Digital Potentiometer (XDCP) manufactured by Xicor Inc. It offers four digitally controlled potentiometers in a single package.

Applications:

• Automatic calibration
• Remote control adjustment
• Programmable gain and offset adjustment
• Motor speed control
• Audio volume control

Features:

• Four independent 256-tap potentiometers
• SPI serial interface
• Non-volatile wiper storage
• Single 5V power supply
• Low power consumption
• End-to-end resistance of 10 kΩ

Benefits:

• Precise and repeatable resistance adjustment
• Easy control via SPI interface
• Retains wiper position even after power loss
• Simplified system design due to single power supply requirement
• Extended battery life in portable applications due to low power consumption

Additional Details:

The X9221WS digital potentiometer provides a precise and reliable method for adjusting resistance values in electronic circuits. The SPI serial interface allows for easy control of the wiper position from a microcontroller. The non-volatile wiper storage ensures that the wiper position is retained even after power is removed. This is particularly useful in applications where calibration or settings need to be preserved. Each of the four potentiometers has 256 taps, providing a high resolution for fine-tuning resistance values.

Operating Temperature: -40°C to +85°C
