Description and Introduction

32-Tap, Nonvolatile, Linear-Taper Digital Potentiometers The MAX5471EZT-T is a digital potentiometer manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features from the manufacturer's knowledge base:  

### **Descriptions:**  
- The MAX5471EZT-T is a **32-tap**, **nonvolatile**, **linear-taper** digital potentiometer.  
- It is designed to replace mechanical potentiometers in applications requiring digitally controlled resistance adjustments.  
- The device operates with a **single +2.7V to +5.5V supply** and features a **3-wire SPI-compatible interface** for digital control.  
- It retains its settings when powered off due to its nonvolatile memory.  

### **Key Features:**  
- **32-Position Resolution**: Provides fine resistance adjustments.  
- **Nonvolatile Memory**: Saves wiper position when power is removed.  
- **Wide Supply Voltage Range**: Operates from **+2.7V to +5.5V**.  
- **Low Power Consumption**:  
  - **0.5µA (typ) standby current**  
  - **1mA (max) active current**  
- **SPI-Compatible 3-Wire Interface**: Allows easy digital control.  
- **End-to-End Resistance Options**: Available in **10kΩ, 50kΩ, and 100kΩ** variants.  
- **Temperature Range**: **-40°C to +85°C** (industrial-grade).  
- **Tiny 8-Pin TDFN Package**: Space-saving footprint (3mm x 3mm).  

### **Applications:**  
- Volume control in audio systems  
- LCD contrast/brightness adjustment  
- Programmable voltage references  
- Sensor calibration  

This information is sourced from the official **MAXIM (now Analog Devices) datasheet** for the MAX5471EZT-T.

Application Scenarios & Design Considerations

32-Tap, Nonvolatile, Linear-Taper Digital Potentiometers

Alternative Part Number

  • AD5220BRMZ10 --: Single-channel digital potentiometer with similar 10k ohm resistance and SPI-compatible interface, widely available and functionally comparable to the MAX5471.
  • MCP4131-103E/P --: SPI-controlled single digital potentiometer with 10k ohm end-to-end resistance, low cost and easy drop-in for many MAX5471 applications.
  • X9C103S --: Well-known 10k ohm digitally controlled potentiometer with up/down interface; usable as an alternative where the SPI interface can be adapted.
  • AD5161BRMZ10 --: Single-channel 10k digital potentiometer with I2C/SPI interface, functionally similar to the MAX5471 and widely available from a different series.
  • MCP4018T-103E/LT --: 10k single digital potentiometer in a small package with I2C control, a good form-fit-function substitute from a different vendor family.
  • DS1803Z-010 --: Dual 10k I2C digital potentiometer from Maxim's DS series, usable as an alternative when a different series naming is acceptable.
