### **Descriptions:**  
The MAX4081FASA+ is a precision, high-side current-sense amplifier designed for monitoring current in applications such as power management, battery charging, and motor control. It operates over a wide supply voltage range and provides a ground-referenced output proportional to the load current.  

### **Features:**  
- Wide input common-mode voltage range (4.5V to 76V)  
- Low quiescent current (60µA typical)  
- Fixed gain options (20V/V, 50V/V, 100V/V)  
- High accuracy (±1% max gain error)  
- Small SOIC-8 package  
- Extended temperature range (-40°C to +125°C)  
- Reverse battery protection up to -16V  

This device is commonly used in automotive, industrial, and telecom applications for accurate current monitoring.
