Description and Introduction

8-Bit Parallel DAC in QSOP-16 Package The MAX5480BCEE 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:**
- **Type:** Digital Potentiometer (Non-Volatile, 10kΩ)  
- **Interface:** 3-Wire SPI-Compatible  
- **Resolution:** 256 Taps  
- **Resistance Value:** 10kΩ  
- **Tolerance:** ±20%  
- **Temperature Coefficient:** 35ppm/°C  
- **Supply Voltage Range:** 2.7V to 5.25V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin QSOP (QSOP-16)  
- **Non-Volatile Memory:** Yes (Retains settings when powered off)  
- **Wiper Current:** ±1mA (max)  

### **Descriptions:**
The MAX5480BCEE is a digitally controlled potentiometer that emulates mechanical potentiometers but offers higher reliability and precision. It features non-volatile memory, allowing it to retain its last setting even after power cycling. It is designed for applications requiring programmable resistance adjustments, such as volume control, calibration, and sensor trimming.

### **Features:**
- **Non-Volatile Wiper Storage:** Saves settings without power.  
- **Low Power Consumption:** Ideal for battery-operated devices.  
- **SPI-Compatible Interface:** Simple digital control.  
- **256-Tap Resolution:** Provides fine adjustment capability.  
- **Wide Supply Voltage Range (2.7V–5.25V):** Supports both 3V and 5V systems.  
- **Small Footprint (QSOP-16):** Space-efficient for compact designs.  
- **End-to-End Resistance Tolerance:** ±20% (typical).  
- **Low Wiper Resistance:** 100Ω (typ).  

This information is based solely on the manufacturer's datasheet. For detailed electrical characteristics and application circuits, refer to the official documentation.

Application Scenarios & Design Considerations

8-Bit Parallel DAC in QSOP-16 Package

Alternative Part Number

  • AD5421BRUZ --: Similar 8-bit multiplying DAC function with comparable interface and supply range; Analog Devices is a direct second source for Maxim DACs.
  • MCP4822-E/P --: Dual 12-bit DAC with SPI interface that can replace the MAX5480 in many low-speed control applications, widely available and cost effective.
  • DAC8562SDGSR --: 16-bit SPI DAC offering higher resolution and similar serial control interface, suitable as a functional upgrade alternative.
  • AD5420AREZ --: Single-channel 12-bit current-output DAC with similar serial interface and supply range, widely used as a MAX5480 replacement.
  • DAC7512E --: 12-bit voltage-output DAC in small package with SPI interface, pin-functionally comparable and readily available.
  • MCP4921-E/P --: 12-bit SPI DAC with similar resolution and interface, low cost and good availability for drop-in functional substitution.
