Description and Introduction

+/-15 V, 100 kom, dual, 128-tap, low-drift digital potentiometer The MAX5439EUD 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)  
- **Resolution:** 256 taps  
- **Resistance Range:** 10kΩ, 50kΩ, 100kΩ (selectable)  
- **Interface:** 3-Wire SPI-Compatible Serial Interface  
- **Supply Voltage (VDD):** +2.7V to +5.25V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 14-TSSOP  

### **Descriptions:**  
The MAX5439EUD is a nonvolatile, linear-taper digital potentiometer that functions similarly to a mechanical potentiometer but is controlled digitally via an SPI interface. It retains its wiper position when powered off, making it suitable for applications requiring preset adjustments.  

### **Features:**  
- **Nonvolatile Wiper Storage:** Saves settings during power-off.  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **SPI-Compatible Interface:** Allows easy microcontroller interfacing.  
- **End-to-End Resistance Tolerance:** ±20% (typ).  
- **Low Wiper Resistance:** Typically 100Ω.  
- **Wide Operating Voltage Range:** Supports 2.7V to 5.25V.  
- **Industrial Temperature Range:** -40°C to +85°C.  

This device is commonly used in audio equipment, instrumentation, and programmable voltage references.
