Description and Introduction

Dual / 256-Tap / Up/Down Interface / Digital Potentiometers The MAX5452EUB 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:

### **Specifications:**
- **Manufacturer:** Maxim Integrated (now Analog Devices)  
- **Part Number:** MAX5452EUB  
- **Package:** 10-pin µMAX (microMAX)  
- **Interface:** 3-Wire SPI/QSPI/MICROWIRE Compatible  
- **Resolution:** 32 Taps  
- **Resistance Range:** 10kΩ, 50kΩ, 100kΩ (depending on variant)  
- **Operating Voltage:** 2.7V to 5.25V  
- **Temperature Range:** -40°C to +85°C  
- **Non-Volatile Memory:** No (Volatile)  
- **End-to-End Resistance Tolerance:** ±20%  
- **Wiper Resistance:** 100Ω (typical)  
- **Power-On Reset (POR):** Wiper resets to midscale (position 16)  

### **Descriptions:**
The MAX5452EUB is a digitally controlled potentiometer (digipot) that replaces mechanical potentiometers in applications requiring programmable resistance. It features a 3-wire SPI-compatible interface for digital control and offers 32 tap points for precise adjustments. The device operates over a wide voltage range, making it suitable for battery-powered and low-voltage systems.  

### **Features:**
- **SPI-Compatible Serial Interface** – Allows easy digital control.  
- **Low Power Consumption** – Ideal for portable/battery-operated devices.  
- **32 Taps Resolution** – Provides fine adjustment capability.  
- **Wide Supply Voltage Range (2.7V to 5.25V)** – Compatible with 3V and 5V systems.  
- **No Non-Volatile Memory** – Wiper position is volatile (resets on power-up).  
- **Small µMAX Package (10-pin)** – Saves board space in compact designs.  
- **Power-On Reset to Midscale** – Ensures known starting condition.  

This information is based on the manufacturer's datasheet and technical documentation. For detailed electrical characteristics, refer to the official datasheet from Analog Devices (formerly Maxim Integrated).

Application Scenarios & Design Considerations

Alternative Part Number

  • AD5222BRUZ10 --: Dual 10k digital potentiometer in TSSOP-10, functionally similar to the MAX5452 dual pot and pin-compatible in many designs.
  • MCP42100-I/ST --: Dual 100k SPI digital potentiometer in TSSOP-14, offers similar dual-channel digital pot functionality with wide availability.
  • X9C103PZ --: Single 10k 100-tap digital potentiometer, a common alternative when a single-channel digital pot can substitute the MAX5452 function.
  • AD5246BRMZ10 --: Single-channel I2C digital potentiometer with 10k ohm resistance, functionally similar to the MAX5452 and available from a different vendor.
  • MCP4017T-103E/LT --: I2C digital potentiometer in a small package with comparable resolution and interface, suitable as a drop-in functional replacement.
  • DS1803Z-010 --: Dual I2C digital potentiometer from the same manufacturer family, offering similar I2C control and resistance options.
