Description and Introduction

Precision, High-Side Current-Sense Amplifiers The MAX471CSA is a precision, high-side current-sense amplifier manufactured by Maxim Integrated.  

### **Specifications:**  
- **Supply Voltage Range:** +2.7V to +36V  
- **Current Measurement Range:** ±3A  
- **Gain Accuracy:** ±1% (max)  
- **Bandwidth:** 500kHz (typical)  
- **Common-Mode Input Range:** 0V to +36V  
- **Quiescent Current:** 60µA (typical)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 8-pin SOIC  

### **Descriptions:**  
The MAX471CSA is designed for high-side current sensing in battery-powered systems, power management, and industrial applications. It provides a voltage output proportional to the load current, eliminating the need for a sense resistor in the ground path.  

### **Features:**  
- High-side current sensing  
- Low offset voltage (50µV max)  
- Internal sense resistor (35mΩ typical)  
- Wide input common-mode range  
- Low power consumption  
- Rail-to-rail output swing  
- Reverse battery protection  

This device is commonly used in battery chargers, power supplies, and automotive systems for accurate current monitoring.
