**Descriptions:**  
The X9251TS24-2.7 is a digitally controlled potentiometer (XDCP) that operates via an I²C interface. It provides non-volatile storage of wiper settings, allowing the device to retain its position even when power is removed.  

**Features:**  
- Non-volatile memory stores wiper position  
- Low power consumption  
- 256-position resolution  
- I²C-compatible interface  
- Power-on recall of saved wiper setting  
- Endurance: 100,000 data changes per bit  
- Data retention: 100 years  

This device is commonly used in applications requiring adjustable resistance, such as calibration, volume control, and programmable voltage references.

Application Scenarios & Design Considerations

Quad Digitally-Controlled (XDCP?) Potentiometer

Alternative Part Number

  • AD5231BRUZ10 --: Single-channel 10k digital potentiometer with SPI interface, functionally similar to the X9251 and available in a TSSOP package.
  • MCP42100-I/SL --: Dual 100k SPI digital potentiometer offering comparable non-volatile wiper functionality in a similar small package.
  • DS1803Z-010 --: Dual 10k I2C digital potentiometer that can replace the X9251 in many low-voltage control applications.
