Description and Introduction

4.5 Dual SPST Analog Switches in UCSP The MAX4722EUA is a precision, high-side current-sense amplifier manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Supply Voltage Range:** +2.7V to +28V  
- **Input Common-Mode Voltage Range:** +4V to +28V  
- **Gain Accuracy:** ±0.5% (max)  
- **Gain Options:** 20V/V, 50V/V, 100V/V  
- **Bandwidth:** 250kHz (typical)  
- **Quiescent Current:** 60µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin µMAX  

### **Descriptions:**
- The MAX4722EUA is designed for high-side current sensing in applications like battery monitoring, power management, and industrial systems.  
- It provides a ground-referenced output proportional to the load current, eliminating the need for level-shifting circuitry.  
- The device operates with a wide supply voltage range and maintains high accuracy over temperature.  

### **Features:**
- **High-Side Current Sensing:** Monitors current without disrupting the ground path.  
- **Wide Input Common-Mode Range:** Supports operation from +4V to +28V.  
- **Low Offset Voltage:** Ensures accurate current measurement.  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **Small Footprint:** 8-pin µMAX package saves board space.  
- **Internal Gain Resistors:** Eliminates the need for external components.
