Description and Introduction

Low Noise, Low Power, 100 Taps The part **X9317WV8I-2.7** is a digital potentiometer manufactured by **Intersil** (now part of Renesas Electronics). Below are its key specifications, descriptions, and features based on available data:  

### **Specifications:**  
- **Type:** Digitally Controlled Potentiometer (XDCP)  
- **Resistance Value:** 10 kΩ  
- **Number of Taps:** 100  
- **Interface:** Up/Down (Increment/Decrement)  
- **Supply Voltage (VCC):** **2.7V to 5.5V** (specifically optimized for 2.7V operation)  
- **Low Power Consumption:** Typically **3µA** (standby current)  
- **Temperature Range:** **-40°C to +85°C** (Industrial Grade)  
- **Package:** **8-Lead SOIC (Small Outline IC)**  
- **Non-Volatile Memory:** Retains wiper position when powered off  
- **End-to-End Resistance Tolerance:** ±20%  
- **Wiper Resistance:** Typically **40Ω**  

### **Descriptions & Features:**  
- **Digital Potentiometer:** Replaces mechanical potentiometers with a solid-state solution.  
- **100 Tap Points:** Provides fine resolution adjustments.  
- **Non-Volatile Storage:** Saves wiper position during power-off.  
- **Low Power Operation:** Suitable for battery-powered applications.  
- **Incremental Control:** Simple up/down interface for adjusting resistance.  
- **Wide Voltage Range:** Operates from **2.7V to 5.5V**, making it versatile for different systems.  
- **Industrial Temperature Range:** Reliable performance in harsh environments.  

This part is commonly used in applications requiring adjustable resistance, such as:  
- Volume control  
- LCD contrast adjustment  
- Sensor calibration  
- Programmable voltage references  

For exact details, always refer to the official **Intersil datasheet** (now Renesas).

Application Scenarios & Design Considerations

Low Noise, Low Power, 100 Taps

Alternative Part Number

  • ISL23315TFUZ-T7A --: Single-channel I2C digital potentiometer with 32 taps and 2.7V operation, functionally similar to the X9317 and from the successor line of Xicor's product family.
  • MCP4551-103E/MS --: Single I2C digital potentiometer with 10k ohm resistance and low-voltage operation, suitable as a functional replacement with a different series naming.
  • AD5241BRZ10 --: I2C-compatible 10k ohm digital potentiometer with wide supply range, offering comparable function for designs needing an alternative source.
  • ISL23315TFUZ --: Single-channel digital potentiometer with I2C interface and non-volatile memory, functionally similar to the X9317 family; Renesas continues the Intersil portfolio.
  • MCP4017T-103E/LT --: Single digital potentiometer with I2C control and 10k ohm resistance, a common drop-in style alternative for low-voltage digital pot applications.
