- **Non-Volatile Memory:** Retains settings when powered off  
- **Package Options:** 8-pin DIP, SOIC  

### **Descriptions and Features:**  
- **Digitally Controlled Potentiometer:** Replaces mechanical potentiometers with electronic control.  
- **Non-Volatile Memory:** Saves wiper position even when power is removed.  
- **Incremental Adjustment:** Allows step-by-step wiper movement via up/down signals.  
- **Wide Resistance Tolerance:** ±20% end-to-end resistance variation.  
- **Low Power Operation:** Suitable for battery-powered applications.  
- **Simple Serial Interface:** Easy integration with microcontrollers.  
- **Endurance:** 100,000 data changes per bit.  
- **Applications:** Used in volume control, calibration, LCD contrast adjustment, and programmable voltage references.  

This device is designed for precision adjustments in electronic circuits where mechanical potentiometers are impractical.
