Description and Introduction

Low-Cost / Low-Power / 8-Bit DACs with 2-Wire Serial Interface in SOT23 The MAX5380LEUK is a 256-tap, nonvolatile, low-power digital potentiometer from Maxim Integrated.  

### **Specifications:**  
- **Resolution:** 8-bit (256 taps)  
- **Interface:** I²C-compatible (2-wire serial)  
- **Supply Voltage (VDD):** 2.7V to 5.5V  
- **End-to-End Resistance:** 10kΩ, 50kΩ, 100kΩ (options)  
- **Nonvolatile Memory:** Saves wiper position at power-down  
- **Low Power Consumption:**  
  - **Active Mode:** 0.4mA (max)  
  - **Shutdown Mode:** 1μA (max)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT23-5  

### **Descriptions:**  
The MAX5380LEUK is a digital potentiometer that functions similarly to a mechanical potentiometer but is controlled digitally via an I²C interface. It features nonvolatile memory, allowing it to retain the wiper position even when power is removed.  

### **Features:**  
- **Nonvolatile Wiper Storage:** Retains settings during power-off  
- **Low Power Operation:** Suitable for battery-powered applications  
- **I²C Interface:** Simple 2-wire digital control  
- **Small Footprint:** Available in a compact SOT23-5 package  
- **Wide Supply Range:** Operates from 2.7V to 5.5V  

This device is commonly used in applications requiring programmable resistance, such as volume control, LCD contrast adjustment, and calibration circuits.
