Description and Introduction

Dual / 256-Tap / Low-Drift / Digital Potentiometers in 14-Pin TSSOP The MAX5414EUD is a digital potentiometer manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Resolution:** 256 taps  
- **Interface Type:** SPI-compatible (3-wire)  
- **Supply Voltage Range:** 2.7V to 5.5V  
- **Resistance Options:** 10kΩ, 50kΩ, 100kΩ  
- **Temperature Range:** -40°C to +85°C  
- **Package:** 14-TSSOP  
- **Non-Volatile Memory:** No (volatile wiper setting)  
- **Low Power Consumption:** 5µA (max) supply current  
- **End-to-End Resistance Tolerance:** ±20%  
- **Wiper Resistance:** 100Ω (typical)  

### **Descriptions:**  
The MAX5414EUD is a digitally controlled potentiometer (digipot) that replaces mechanical potentiometers in applications requiring programmable resistance. It is controlled via an SPI-compatible interface and offers 256-tap resolution for precise adjustments.  

### **Features:**  
- **SPI-Compatible Serial Interface** for easy digital control  
- **Wide Supply Voltage Range (2.7V–5.5V)** for flexibility in different systems  
- **Low Power Consumption** (5µA max) for battery-operated applications  
- **Small 14-TSSOP Package** saves board space  
- **Volatile Wiper Setting** (resets to mid-scale on power-up)  
- **High Reliability** with no mechanical wear  

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