Description and Introduction

Dual, 256-Tap, Nonvolatile, I²C-Interface, Digital Potentiometers The MAX5478EUD+ 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  
- **Number of Channels:** 1  
- **Taper:** Linear  
- **Resistance Value:** 50 kΩ  
- **Number of Positions:** 256  
- **Interface:** I²C (2-Wire Serial)  
- **Supply Voltage (VDD):** 2.7V to 5.25V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 14-TSSOP  
- **Resolution:** 8-bit (256 taps)  
- **Non-Volatile Memory:** No  
- **Low Power Consumption:** 3 µA (standby), 1 mA (active)  

### **Descriptions:**
The MAX5478EUD+ is a single-channel, linear-taper digital potentiometer that replaces mechanical potentiometers. It provides 256 tap points and operates via an I²C interface, allowing digital control of resistance. It is designed for applications requiring precision adjustments in analog circuits.

### **Features:**
- **I²C-Compatible Interface** for easy digital control  
- **Low Power Consumption** for battery-operated devices  
- **Wide Supply Voltage Range** (2.7V to 5.25V)  
- **50 kΩ End-to-End Resistance**  
- **256-Tap Resolution** for fine adjustments  
- **No Non-Volatile Memory** (volatile wiper setting)  
- **Small 14-TSSOP Package** for space-constrained designs  

This device is commonly used in audio equipment, instrumentation, and industrial control systems where digital adjustment of resistance is required.
