Description and Introduction

256-Tap SOT-PoT, Low-Drift Digital Potentiometers in SOT23 The MAX5400EKA-T is a digital potentiometer manufactured by Maxim Integrated. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Category:** Integrated Circuits (ICs)  
- **Type:** Digital Potentiometer  
- **Package:** SOT-23-8  
- **Resistance Value:** 50 kΩ  
- **Number of Taps:** 256  
- **Interface:** SPI  
- **Operating Voltage:** 2.7V to 5.5V  
- **Temperature Range:** -40°C to +85°C  
- **Resolution:** 8-bit (256 steps)  
- **End-to-End Resistance Tolerance:** ±20%  
- **Low Wiper Resistance:** 125Ω (typical)  
- **Low Power Consumption:** 0.5µA (standby current)  

### **Descriptions:**  
The MAX5400EKA-T is a single-channel, volatile, 256-tap digital potentiometer with an SPI-compatible interface. It is designed to replace mechanical potentiometers in applications requiring digital control of resistance. The device operates from a single 2.7V to 5.5V supply and is suitable for use in audio systems, instrumentation, and programmable voltage references.  

### **Features:**  
- **SPI-Compatible Serial Interface**  
- **Single 50 kΩ Potentiometer**  
- **Low Power Consumption**  
- **Volatile Memory (Resets to Midscale on Power-Up)**  
- **Compact SOT-23-8 Package**  
- **Wide Operating Voltage Range (2.7V to 5.5V)**  
- **High Reliability (No Moving Parts)**  

This information is based solely on the manufacturer's datasheet and specifications. No additional recommendations or interpretations are included.

Application Scenarios & Design Considerations

256-Tap SOT-PoT, Low-Drift Digital Potentiometers in SOT23

Alternative Part Number

  • AD5160BRJZ10-RL7 --: Single-channel 10k digital potentiometer in SOT-23, functionally similar to the MAX5400 and pin-compatible in many designs.
  • MCP4017T-103E/LT --: 10k single digital potentiometer with I2C interface in a small SC-70 package, suitable as a drop-in functional replacement.
  • DS1803Z-010+ --: Dual 10k digital potentiometer from the same vendor family, usable when a dual-channel part can substitute the single-channel MAX5400.
