Description and Introduction

Octal, 13-Bit Voltage-Output DAC with Parallel Interface The MAX547AEQH+D 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  
- **Series:** MAX547  
- **Type:** Digital Potentiometer  
- **Package:** 16-QSOP  
- **Interface:** Up/Down (U/D)  
- **Number of Taps:** 256  
- **Resistance Values:** 10kΩ, 50kΩ, 100kΩ  
- **Supply Voltage:** 2.7V to 5.25V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Non-Volatile Memory:** Yes (Retains settings during power-off)  
- **Resolution:** 8-bit (256 steps)  
- **Low Power Consumption:** Typically 3µA (standby)  

### **Descriptions:**  
The MAX547AEQH+D is a non-volatile, linear-taper digital potentiometer that emulates mechanical potentiometers with digital control. It features an up/down interface for adjusting resistance values and retains settings when powered off. It is suitable for applications requiring digitally controlled resistance adjustments.  

### **Features:**  
- Non-volatile memory stores wiper position  
- Low power consumption  
- 256-tap resolution  
- Wide operating voltage range (2.7V to 5.25V)  
- Up/Down interface for simple control  
- Available in 10kΩ, 50kΩ, and 100kΩ resistance options  
- Compact 16-QSOP package  

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