Description and Introduction

Low Noise, Low Power, 32 Taps Here are the factual details about the **X9315UM-2.7** from the manufacturer **XICOR**:

### **Specifications:**
1. **Manufacturer:** XICOR  
2. **Part Number:** X9315UM-2.7  
3. **Type:** Digitally Controlled Potentiometer (XDCP™)  
4. **Resistance Value:** 10 kΩ  
5. **Number of Taps:** 100  
6. **Interface:** Up/Down (Increment/Decrement)  
7. **Supply Voltage (VCC):** 2.7V to 5.5V  
8. **Operating Temperature Range:** -40°C to +85°C  
9. **Package:** 8-Pin SOIC (UM)  

### **Descriptions:**
- The **X9315UM-2.7** is a non-volatile, digitally controlled potentiometer (XDCP™) that provides 100 resistive steps.  
- It is designed for applications requiring adjustable resistance controlled via digital signals.  
- The device retains its wiper position even when power is removed, due to non-volatile EEPROM storage.  

### **Features:**
- **100 Taps:** Provides fine resolution for resistance adjustments.  
- **Non-Volatile Memory:** Saves wiper position when powered off.  
- **Low Power Consumption:** Suitable for battery-operated devices.  
- **Wide Operating Voltage:** Supports 2.7V to 5.5V.  
- **End-to-End Resistance:** 10 kΩ ±20%.  
- **Incremental Control Interface:** Simple up/down adjustment.  
- **Small Footprint:** 8-pin SOIC package for space-constrained designs.

Application Scenarios & Design Considerations

Low Noise, Low Power, 32 Taps

Alternative Part Number

  • ISL23315UFUZ-T7A --: Single-channel 32-tap I2C digital potentiometer in the same 2.7V class; Renesas acquired Xicor's digital pot line, so this is the closest functional successor.
  • MCP4551-103E/MS --: Single 10k 256-tap I2C digital potentiometer with non-volatile wiper, a widely available drop-in style alternative for X9315 applications.
  • AD5241BRZ10 --: I2C 256-position digital potentiometer rated for 2.7V operation, offering comparable resolution and interface for direct replacement.
  • ISL23315UFRUZ-T7A --: Renesas/Intersil single-channel 32-tap I2C digital potentiometer in the same family lineage, 2.7V-capable supply range and similar volatile wiper architecture, making it a strong functional replacement.
  • MCP4551-502E/MS --: Single 32-tap I2C digital potentiometer with 5k ohm end-to-end resistance and 2.7V operation, offering comparable wiper resolution and interface in a different vendor series.
  • AD5220BRMZ10 --: Single digital potentiometer with similar 10k ohm end-to-end resistance and SPI-like up/down interface, widely available and functionally comparable to the X9315.
  • MCP4131-103E/P --: SPI-controlled single digital potentiometer with 10k ohm resistance, low voltage operation, and similar non-volatile wiper memory behavior.
  • DS1803Z-010 --: Dual I2C digital potentiometer with 10k ohm resistance; one channel can substitute the single-channel X9315 with comparable 2.7V operation.
  • AD5241BRUZ10 --: I2C-compatible 256-position digital potentiometer offering similar volatile wiper control and low-voltage operation as a cross-vendor alternative.
  • MCP4531-103E/MS --: Single 10k I2C digital potentiometer in MSOP, widely available and suitable as a functional replacement for low-voltage digital pot applications.
