Description and Introduction

Precision, High-Side Current-Sense Amplifiers **Manufacturer:** MAXIM (now part of Analog Devices)  

**Part Number:** MAX471CSA+  

### **Specifications:**  
- **Type:** Precision, High-Side Current-Sense Amplifier  
- **Supply Voltage Range:** 3V to 36V  
- **Current Measurement Range:** ±3A (with external sense resistor)  
- **Gain Accuracy:** ±0.5% (typical)  
- **Bandwidth:** 500kHz  
- **Input Offset Voltage:** ±50µV (max)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 8-pin SOIC  

### **Descriptions:**  
The MAX471CSA+ is a precision current-sense amplifier designed for high-side current measurement in applications such as battery monitoring, power management, and motor control. It provides accurate current sensing with minimal power loss due to its integrated precision amplifier and low offset voltage.  

### **Features:**  
- High-side current sensing  
- Wide supply voltage range (3V to 36V)  
- Low 35µΩ (typical) sense resistor requirement  
- Rail-to-rail output swing  
- Low quiescent current (60µA typical)  
- Integrated precision amplifier for accurate measurements  
- Small SOIC package for space-constrained applications  

This device eliminates the need for external level-shifting circuitry, making it suitable for battery-powered and industrial systems.
