Description and Introduction

Dual, 256-Tap, Nonvolatile, SPI-Interface, Linear-Taper Digital Potentiometers The MAX5489ETE#TG16 is a digital potentiometer manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Type:** Digital Potentiometer  
- **Package:** 16-TQFN (3x3)  
- **Resolution:** 10-bit (1024 taps)  
- **Number of Channels:** 1  
- **Interface:** SPI  
- **Resistance Values:** 10kΩ, 50kΩ, 100kΩ  
- **Supply Voltage:** 2.7V to 5.25V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Non-Volatile Memory:** Yes (retains settings after power-off)  
- **Low Wiper Resistance:** 50Ω (typical)  

### **Descriptions:**  
The MAX5489ETE#TG16 is a single-channel, non-volatile digital potentiometer with an SPI interface. It provides a 10-bit resolution and supports resistance values of 10kΩ, 50kΩ, or 100kΩ. It is designed for applications requiring precision adjustments, such as calibration, volume control, and programmable voltage references.  

### **Features:**  
- **Non-volatile memory** retains wiper position during power-off.  
- **Low power consumption** (0.5µA standby current).  
- **SPI-compatible interface** for easy digital control.  
- **Wide operating voltage range** (2.7V to 5.25V).  
- **50Ω typical wiper resistance** for minimal signal distortion.  
- **End-to-end resistance tolerance:** ±20%.  
- **Small 16-TQFN package (3x3mm)** for space-constrained designs.  

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

Application Scenarios & Design Considerations

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

Alternative Part Number

  • AD5161BRMZ10 --: Single-channel 10k digital potentiometer with I2C/SPI interface, functionally similar to the MAX5489 and available from a major alternate vendor.
  • MCP4018T-103E/CH --: 10k single digital potentiometer with I2C control in a small package, suitable as a lower-cost functional replacement.
  • DS1803Z-010+ --: Dual 10k I2C digital potentiometer from the same vendor family, usable when a dual-channel part can substitute for the original.
