Description and Introduction

Octal, 13-Bit Voltage-Output DAC with Parallel Interface The MAX547AEMH is a precision, dual, 256-tap, nonvolatile, linear-taper digital potentiometer manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Resolution:** 8-bit (256 taps per potentiometer)  
- **Number of Potentiometers:** Dual (two independent potentiometers)  
- **Interface:** 3-Wire SPI-Compatible Serial Interface  
- **End-to-End Resistance:** 50 kΩ  
- **Nonvolatile Memory:** Stores wiper position during power-off  
- **Supply Voltage (VDD):** 2.7V to 5.25V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Pin TSSOP  

### **Descriptions:**
- The MAX547AEMH is a digitally controlled potentiometer (digipot) that replaces mechanical potentiometers.  
- It features two independent potentiometers with nonvolatile memory, allowing the wiper position to be retained when power is removed.  
- The device operates via a 3-wire SPI-compatible serial interface for digital control.  
- It is designed for applications requiring precision adjustments, such as calibration, offset trimming, and programmable voltage dividers.  

### **Features:**
- **Dual Nonvolatile Potentiometers:** Two independent 256-tap potentiometers in one package.  
- **SPI-Compatible Interface:** Simple 3-wire control for easy integration.  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **Wide Operating Voltage:** Supports 2.7V to 5.25V supply range.  
- **High Reliability:** No mechanical wear, unlike traditional potentiometers.  
- **Industrial Temperature Range:** Operates from -40°C to +85°C.
