Description and Introduction

Octal, 13-Bit Voltage-Output DAC with Parallel Interface The MAX547ACQH 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:**
- **Type:** Digital Potentiometer (DigiPot)  
- **Resolution:** 256 taps  
- **Number of Channels:** 1  
- **Interface:** Serial (SPI-compatible)  
- **Resistance Range:** 50 kΩ  
- **Supply Voltage Range:** 2.7V to 5.5V  
- **Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin QSOP (Quarter Small Outline Package)  
- **Non-Volatile Memory:** Yes (EEPROM stores wiper position)  
- **Low Power Consumption:** Typically 3µA (standby current)  

### **Descriptions:**
The MAX547ACQH is a digitally controlled potentiometer that replaces mechanical potentiometers in applications requiring programmable resistance adjustments. It features a non-volatile EEPROM to retain the wiper position when power is removed. It is designed for precision analog adjustments in systems such as audio equipment, instrumentation, and industrial controls.

### **Features:**
- **256-Tap Resolution:** Provides fine adjustment capability.  
- **SPI-Compatible Interface:** Allows easy digital control.  
- **Non-Volatile Wiper Storage:** Saves settings during power-off.  
- **Low Power Consumption:** Suitable for battery-powered applications.  
- **Wide Operating Voltage:** Supports 2.7V to 5.5V operation.  
- **Small Package (QSOP-16):** Space-efficient for compact designs.  
- **End-to-End Resistance Tolerance:** Tight tolerance for accurate performance.  

This information is based on the manufacturer's datasheet and technical documentation. For detailed electrical characteristics and application notes, refer to the official MAX547 datasheet.
