Description and Introduction

Low-Power Digital Potentiometers The MAX5161LEZT is a digital potentiometer manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Category:** Digital Potentiometer  
- **Package:** 16-TSSOP  
- **Resistance Value:** 50 kΩ  
- **Number of Taps:** 256  
- **Interface:** I²C-Compatible  
- **Supply Voltage Range:** 2.7V to 5.5V  
- **Temperature Range:** -40°C to +85°C  
- **Resolution:** 8-bit (256 steps)  
- **Non-Volatile Memory:** No  
- **Low Power Consumption:** 3µA (standby)  
- **End-to-End Resistance Tolerance:** ±20%  

### **Descriptions:**  
The MAX5161LEZT is a digitally controlled potentiometer that functions similarly to a mechanical potentiometer but is controlled via an I²C interface. It is designed for applications requiring adjustable resistance, such as volume control, LCD contrast adjustment, and programmable voltage references.  

### **Features:**  
- **I²C-Compatible Interface** – Allows easy digital control.  
- **Wide Operating Voltage** – Supports 2.7V to 5.5V.  
- **256-Tap Resolution** – Provides fine adjustment capability.  
- **Low Power Consumption** – Ideal for battery-powered applications.  
- **Compact TSSOP Package** – Suitable for space-constrained designs.  
- **No Non-Volatile Memory** – Requires reinitialization on power-up.  

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

Application Scenarios & Design Considerations

Low-Power Digital Potentiometers

Alternative Part Number

  • MCP4017T-104E/LT --: Single-channel I2C digital potentiometer with 100k ohm resistance, functionally similar to the MAX5161 in a small SOT-23 package.
  • AD5241BRZ10 --: I2C-compatible digital potentiometer offering comparable resolution and interface, suitable as a direct functional replacement.
  • DS1803Z-010 --: Dual I2C digital potentiometer from the same vendor family, usable where one channel of a similar 10k device is acceptable.
  • MCP4011-103E/SN --: Single-channel 10k digital potentiometer with SPI interface, functionally similar to the MAX5161 and widely available.
  • AD5161BRMZ10 --: 10k single digital potentiometer with SPI control, comparable resolution and package, good drop-in functional alternative.
  • X9C103S --: 10k digitally controlled potentiometer with up/down interface, commonly used as a substitute for MAX5161-type parts.
