Description and Introduction

±15V Digitally Programmable Precision Voltage-Dividers for PGAs The MAX5431BEUB 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 (8-bit)  
- **Resistance Range:** 10kΩ, 50kΩ, or 100kΩ (depending on variant)  
- **Interface:** SPI-compatible (3-wire)  
- **Supply Voltage:** 2.7V to 5.25V  
- **Temperature Range:** -40°C to +85°C  
- **Package:** 10-pin µMAX® (3mm x 5mm)  
- **Non-Volatile Memory:** No (volatile wiper setting)  
- **Low Wiper Resistance:** 120Ω (typical)  
- **Low Power Consumption:** 3µA (standby current)  

### **Descriptions:**
The MAX5431BEUB is a digitally controlled variable resistor (potentiometer) that replaces mechanical potentiometers. It provides a programmable resistance via an SPI interface, making it suitable for applications requiring precision adjustments in analog circuits.  

### **Features:**
- **SPI-Compatible Serial Interface** – Allows easy digital control.  
- **Wide Operating Voltage** – Supports 2.7V to 5.25V for flexibility in different systems.  
- **Low Power Consumption** – Ideal for battery-powered applications.  
- **Small Footprint** – 10-pin µMAX package saves board space.  
- **No Non-Volatile Memory** – Wiper position resets on power-up (volatile operation).  
- **High Reliability** – Eliminates mechanical wear and tear.  

For exact resistance value options (10kΩ, 50kΩ, or 100kΩ), refer to the specific part number variant.
