Description and Introduction

Low-Cost, Low-Power, 8-Bit DACs with 2-Wire Serial Interface in SOT23 The MAX5381MEUK+T is a digital potentiometer manufactured by Maxim Integrated (now part of Analog Devices).  

### **Specifications:**  
- **Type:** Non-volatile, 256-tap digital potentiometer  
- **Resistance Range:** 10 kΩ  
- **Interface:** I²C-compatible (2-wire serial interface)  
- **Supply Voltage (VDD):** 2.7V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT23-8  
- **Resolution:** 8-bit (256 positions)  
- **Low Power Consumption:** 3 µA (standby current)  
- **End-to-End Resistance Tolerance:** ±20%  
- **Non-Volatile Memory:** Retains wiper position when powered off  

### **Descriptions and Features:**  
- **Non-Volatile Memory:** Saves the wiper position without requiring external components.  
- **I²C Interface:** Allows easy digital control with a microcontroller.  
- **Low Power Consumption:** Suitable for battery-powered applications.  
- **Wide Voltage Range:** Operates from 2.7V to 5.5V, making it versatile for different systems.  
- **Small Form Factor:** SOT23-8 package is ideal for space-constrained designs.  
- **Applications:** Used in volume control, LCD contrast adjustment, programmable power supplies, and sensor calibration.
