Description and Introduction

10-Bit, Nonvolatile, Linear-Taper Digital Potentiometers The MAX5481EUD+ is a digital potentiometer manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Type:** Digital Potentiometer (DigiPot)  
- **Configuration:** Single, 256-Tap Positions  
- **Resistance Range:** 10 kΩ, 50 kΩ  
- **Interface:** SPI-Compatible (3-Wire)  
- **Supply Voltage (VDD):** 2.7V to 5.25V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 14-TSSOP  
- **Resolution:** 8-bit (256 Steps)  
- **Non-Volatile Memory:** Yes (Retains Settings on Power-Down)  
- **End-to-End Resistance Tolerance:** ±20%  
- **Low Power Consumption:**  
  - 0.5µA (Standby Current)  
  - 1mA (Active Current)  

### **Descriptions:**
The MAX5481EUD+ is a non-volatile, digitally controlled potentiometer that replaces mechanical potentiometers in applications requiring programmable resistance. It features an SPI-compatible interface for digital control and retains its settings even when powered off.  

### **Features:**
- **Non-Volatile Memory:** Saves wiper position during power-off.  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **SPI-Compatible Interface:** Simple 3-wire control.  
- **Wide Supply Voltage Range:** Operates from 2.7V to 5.25V.  
- **End-to-End Resistance Options:** 10 kΩ or 50 kΩ.  
- **Small Package (14-TSSOP):** Space-efficient for compact designs.  
- **High Reliability:** No mechanical wear, unlike traditional potentiometers.  

This device is commonly used in audio systems, instrumentation, and programmable voltage dividers.
