Description and Introduction

+2.5V to +5.5V, Low-Power, Single/Dual, 8-Bit Voltage-Output DACs in レMAX Package The MAX548AEUA is a digital potentiometer manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Resolution:** 8-bit (256 taps)  
- **Interface:** 3-Wire SPI-Compatible  
- **Supply Voltage Range:** 2.7V to 5.25V  
- **Resistance Options:** 10kΩ, 50kΩ, 100kΩ  
- **Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin µMAX (MSOP)  
- **Non-Volatile Memory:** Yes (EEPROM stores wiper position)  
- **Low Power Consumption:**  
  - 3µA (standby current)  
  - 0.5mA (active current)  
- **Wiper Resistance:** 100Ω (typical)  

### **Descriptions:**  
The MAX548AEUA is a digitally controlled potentiometer (digipot) that replaces mechanical potentiometers. It features non-volatile memory (EEPROM) to retain the wiper position when power is removed. The device operates via a 3-wire SPI-compatible interface, allowing microcontroller-based adjustments. It is designed for applications requiring precision adjustments, such as calibration, volume control, and programmable voltage dividers.

### **Features:**  
- **Non-Volatile Wiper Storage:** Saves settings during power-off.  
- **SPI-Compatible Interface:** Simple digital control.  
- **Low Power Consumption:** Suitable for battery-powered devices.  
- **Wide Voltage Range:** Operates from 2.7V to 5.25V.  
- **Small Footprint:** 8-pin µMAX package saves board space.  
- **End-to-End Resistance Tolerance:** ±20%.  
- **Monotonic Operation:** Ensures consistent adjustment.
