Description and Introduction

8-Bit Parallel DAC in QSOP-16 Package The **MAX5480BEEE-T** is a digital potentiometer manufactured by **Maxim Integrated** (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Type:** Digital Potentiometer  
- **Configuration:** Dual-channel, 256-tap positions  
- **Resistance Range:** 10 kΩ, 50 kΩ, 100 kΩ (depending on variant)  
- **Interface:** SPI-compatible (3-wire)  
- **Supply Voltage (VCC):** +2.7V to +5.25V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin QSOP (EE)  
- **Non-Volatile Memory:** Yes (retains settings when powered off)  
- **Resolution:** 8-bit (256 steps)  
- **End-to-End Resistance Tolerance:** ±20%  
- **Low Power Consumption:** Typically 3µA (standby mode)  

### **Descriptions:**  
The **MAX5480BEEE-T** is a dual-channel, non-volatile digital potentiometer designed for precision analog adjustments in applications such as volume control, LCD contrast adjustment, and programmable voltage references. It features an SPI interface for digital control and retains its settings in non-volatile memory when power is removed.  

### **Features:**  
- **Dual Independent Potentiometers:** Two digitally controlled potentiometers in one package.  
- **Non-Volatile Memory:** Saves wiper position during power-off.  
- **SPI-Compatible Interface:** Allows easy digital control with microcontrollers.  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **Wide Operating Voltage Range:** Supports +2.7V to +5.25V.  
- **High Reliability:** Endurance of 50,000 write cycles per bit.  
- **Small Footprint:** 16-pin QSOP package for space-constrained designs.  

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