Description and Introduction

76V, High-Side, Current-Sense Amplifiers with Voltage Output The MAX4081TAUA+ is a high-side current-sense amplifier manufactured by **MAXIM Integrated** (now part of Analog Devices).  

### **Specifications:**  
- **Supply Voltage Range:** 4.5V to 76V  
- **Input Common-Mode Voltage Range:** 4.5V to 76V  
- **Gain Options:** 20V/V, 50V/V, 100V/V  
- **Bandwidth:** 250kHz (typical)  
- **Quiescent Current:** 60µA (typical)  
- **Accuracy:** ±1% (max) gain error  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-pin µMAX  

### **Descriptions:**  
The MAX4081TAUA+ is designed for high-side current sensing in applications such as power management, battery monitoring, and motor control. It provides a ground-referenced output proportional to the load current, eliminating the need for a level-shifting circuit.  

### **Features:**  
- Wide input common-mode voltage range (4.5V to 76V)  
- Low quiescent current (60µA)  
- High accuracy (±1% max gain error)  
- Three fixed gain options (20V/V, 50V/V, 100V/V)  
- Small 8-pin µMAX package  
- Reverse battery protection (up to -20V)  
- No external components required for basic operation  

This device is suitable for automotive, industrial, and telecom applications requiring precise current monitoring.
