Description and Introduction

The Intersil X9511 is a push button controlled potenti ometer that is ideal for push button controlled resis tance trimming Here are the factual details about part X9511WSI from manufacturer XICOR:

### **Specifications:**
1. **Type**: Digital Potentiometer (Non-volatile Memory)
2. **Interface**: 3-Wire Serial (SPI-compatible)
3. **Resolution**: 32 Taps
4. **Resistance Range**: 10 kΩ
5. **End-to-End Resistance Tolerance**: ±20%
6. **Operating Voltage**: 2.7V to 5.5V
7. **Low Power Consumption**:  
   - Standby Current: <1 µA  
   - Active Current: <3 mA  
8. **Temperature Range**:  
   - Commercial: 0°C to +70°C  
   - Industrial: -40°C to +85°C  
9. **Package**: 8-Lead SOIC (Small Outline Integrated Circuit)  

### **Descriptions:**
- The **X9511WSI** is a digitally controlled potentiometer (XDCP™) with non-volatile memory, allowing it to retain settings when power is removed.  
- It provides a 3-wire serial interface for easy integration with microcontrollers.  
- The wiper position is stored in EEPROM, ensuring recall of the last setting upon power-up.  

### **Features:**
- **Non-volatile Storage**: Saves wiper position in EEPROM.  
- **Increment/Decrement Control**: Adjusts resistance via serial commands.  
- **32 Tap Points**: Provides fine resolution adjustment.  
- **Low Power Operation**: Suitable for battery-powered applications.  
- **SPI-Compatible Interface**: Simplifies digital control.  
- **Endurance**: 100,000 write cycles per bit.  
- **Data Retention**: 100 years.  

This information is based solely on the manufacturer's specifications for the **X9511WSI** from **XICOR**.

Application Scenarios & Design Considerations

The Intersil X9511 is a push button controlled potenti ometer that is ideal for push button controlled resis tance trimming

Alternative Part Number

  • DS1803Z-010 --: Dual digital potentiometer with I2C interface, functionally similar to the X9511 push-button controlled potentiometer and available in a comparable SOIC package.
  • AD5220BRZ10 --: Single-channel 10k digital potentiometer with up/down control interface, closely matching the X9511's increment/decrement operation.
  • MCP4131-103E/SN --: SPI-controlled 10k digital potentiometer in SOIC, a widely available modern alternative when a serial interface can replace the push-button control.
  • MCP4011-103E/SN --: 10k ohm single digital potentiometer with simple up/down interface in a small package, offering comparable functionality for push-button controlled resistance adjustment.
  • DS1804-010+ --: Single digital potentiometer with similar 10k ohm resistance and serial control, functionally comparable to the X9511 push-button controlled potentiometer.
