Description and Introduction

Low-Power Digital Potentiometers The MAX5160LEUA 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:

### **Manufacturer:**  
Maxim Integrated (Analog Devices)  

### **Specifications:**  
- **Type:** Digital Potentiometer  
- **Resolution:** 256 taps  
- **Number of Channels:** 1  
- **Interface:** I²C (2-wire serial)  
- **Supply Voltage Range:** 2.7V to 5.5V  
- **Resistance Range:** 10kΩ, 50kΩ, 100kΩ (depending on variant)  
- **Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin µMAX (MSOP)  
- **Non-Volatile Memory:** No (volatile wiper setting)  
- **Low Power Consumption:** 3µA (standby current)  

### **Descriptions:**  
The MAX5160LEUA is a single-channel, digitally controlled potentiometer that functions similarly to a mechanical potentiometer but is controlled via an I²C interface. It is used in applications requiring programmable resistance adjustments, such as volume control, LCD contrast adjustment, and calibration circuits.  

### **Features:**  
- **I²C-Compatible Interface:** Allows easy digital control.  
- **Wide Operating Voltage:** Supports 2.7V to 5.5V, making it suitable for both 3V and 5V systems.  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **Small Footprint:** 8-pin µMAX package saves board space.  
- **No Non-Volatile Memory:** Wiper position resets on power-up (volatile operation).  

For exact resistance values and detailed electrical characteristics, refer to the official datasheet from Maxim Integrated (Analog Devices).

Application Scenarios & Design Considerations

Low-Power Digital Potentiometers

Alternative Part Number

  • MCP4011-103E/SN --: Single digital potentiometer with similar 10k ohm resistance and SPI-like interface, available in SOIC package, good functional substitute.
  • AD5160BRJZ10-RL7 --: 10k ohm digital potentiometer with SPI interface in SOT-23, comparable resolution and performance to the MAX5160.
  • X9C103SIZ --: Widely available 10k ohm digitally controlled potentiometer with up/down interface, suitable drop-in for many MAX5160 applications.
  • AD5160BRJZ10 --: Single-channel 10k digital potentiometer in SOT-23/MSOP, functionally similar SPI-controlled rheostat with comparable resolution and supply range.
  • MCP4131-103E/MS --: SPI-controlled 10k single digital potentiometer in MSOP-8, pin-function compatible alternative with similar 7-bit resolution and wide supply range.
  • DS1803Z-010 --: Dual 10k I2C digital potentiometer from the same vendor family, usable as a drop-in style replacement where I2C control and dual channels are acceptable.
  • DS1803Z-010+ --: Dual 10k ohm digital potentiometer from the same manufacturer family, usable as a higher-integration substitute when board space allows.
