Description and Introduction

Digitally Programmable Precision Voltage Divider for PGAs The MAX5420AEUA+ is a digital potentiometer manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
MAXIM (Maxim Integrated)  

### **Specifications:**  
- **Type:** Digital Potentiometer  
- **Resolution:** 256 taps  
- **Number of Channels:** 1  
- **Interface:** SPI  
- **Resistance Values:** 10kΩ, 50kΩ, 100kΩ  
- **Supply Voltage Range:** 2.7V to 5.25V  
- **Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin µMAX (MSOP)  

### **Descriptions:**  
The MAX5420AEUA+ is a digitally controlled potentiometer that replaces mechanical potentiometers. It provides nonvolatile memory to store wiper settings, ensuring the last position is retained when power is removed. It is designed for precision applications requiring reliable digital adjustment.  

### **Features:**  
- **Nonvolatile Memory:** Retains wiper position during power-off  
- **Low Power Consumption:** 3µA (max) standby current  
- **SPI-Compatible Interface:** Allows easy digital control  
- **End-to-End Resistance Tolerance:** ±20%  
- **Wiper Resistance:** 100Ω (typical)  
- **Monotonic Operation:** Ensures consistent performance  

This information is based solely on the manufacturer's datasheet.
