Description and Introduction

Dual, 256-Tap, Nonvolatile, I²C-Interface, Digital Potentiometers The MAX5478EUD+T is a digital potentiometer manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual details from Ic-phoenix technical data files:  

### **Manufacturer:**  
MAXIM (now part of Analog Devices)  

### **Pb-Free Specifications:**  
- The "+T" suffix in the part number indicates that the device is **lead-free (Pb-free)** and **RoHS compliant**.  
- It complies with the Restriction of Hazardous Substances (RoHS) directive.  

### **Descriptions:**  
- The MAX5478EUD+T is a **dual, 256-tap, nonvolatile, linear-taper digital potentiometer**.  
- It provides two digitally controlled potentiometers in a single package.  
- Nonvolatile memory allows the wiper settings to be saved when power is removed.  
- Operates with a **supply voltage range of 2.7V to 5.25V**.  
- Available in a **14-pin TSSOP package (EUD)**.  

### **Features:**  
- **Dual-channel digital potentiometer** (two independent potentiometers in one IC).  
- **256-tap resolution** for fine adjustments.  
- **Nonvolatile memory** retains wiper position during power-off.  
- **Low temperature coefficient (35 ppm/°C typical)** for stable performance.  
- **I²C-compatible 2-wire serial interface** for communication.  
- **Low power consumption** (0.5µA standby current).  
- **End-to-end resistance options** (10kΩ, 50kΩ, 100kΩ).  
- **Industrial temperature range (-40°C to +85°C)**.  

This information is strictly based on the manufacturer's datasheet and specifications.
