Description and Introduction

Dual, 256-Tap, Nonvolatile, SPI-Interface, Linear-Taper Digital Potentiometers The MAX5488EUD+ 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:**  
- **Manufacturer:** Maxim Integrated (Maxim IC)  
- **Part Number:** MAX5488EUD+  
- **Type:** Digital Potentiometer  
- **Package:** 14-TSSOP  
- **Resistance Value:** 50 kΩ  
- **Number of Taps:** 256  
- **Interface:** SPI  
- **Supply Voltage Range:** 2.7V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Non-Volatile Memory:** Yes (EEPROM)

### **Descriptions:**  
The MAX5488EUD+ is a non-volatile, 256-tap digital potentiometer with an SPI-compatible interface. It provides a programmable resistance value that can be stored in internal EEPROM, retaining settings even when power is removed. It is designed for applications requiring precision adjustments, such as volume control, calibration, and programmable voltage references.  

### **Features:**  
- **Non-Volatile Wiper Storage:** Saves settings during power-off.  
- **SPI Interface:** Allows easy digital control.  
- **Wide Voltage Range:** Operates from 2.7V to 5.5V.  
- **Low Power Consumption:** Suitable for battery-powered devices.  
- **50 kΩ Resistance Range:** Adjustable in 256 steps.  
- **Industrial Temperature Range:** -40°C to +85°C.  
- **Compact Package:** 14-TSSOP for space-constrained designs.

Application Scenarios & Design Considerations

Dual, 256-Tap, Nonvolatile, SPI-Interface, Linear-Taper Digital Potentiometers

Alternative Part Number

  • AD5206BRUZ10 --: Quad 10k digital potentiometer in TSSOP-14, functionally similar to the MAX5488 dual/quad digital pot and pin-compatible in many designs.
  • MCP4251-103E/ST --: Dual 10k SPI digital potentiometer in TSSOP-14, a common drop-in style alternative for low-voltage digital pot applications.
  • X9C103SIZ --: Single 10k digitally controlled potentiometer with up/down interface, widely available and suitable when a simpler 3-wire control pot is acceptable.
  • X9C103SIZT1 --: 10k non-volatile digital potentiometer with simple up/down interface, suitable when SPI control is not mandatory.
