Description and Introduction

76V, High-Side, Current-Sense Amplifiers with Voltage Output The MAX4081SAUA+T is a high-side current-sense amplifier manufactured by Maxim Integrated (now part of Analog Devices).  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX4081SAUA+T  
- **Package:** 8-pin µMAX  
- **Supply Voltage Range:** 4.5V to 76V  
- **Input Common-Mode Voltage Range:** 4.5V to 76V  
- **Gain Options:**  
  - MAX4081T: 20V/V  
  - MAX4081S: 60V/V  
  - MAX4081F: 100V/V  
- **Bandwidth:** 200kHz (typical)  
- **Quiescent Current:** 300µA (typical)  
- **Operating Temperature Range:** -40°C to +125°C

- **Accuracy:** ±1.5% (max) over temperature  

### **Descriptions:**  
The MAX4081SAUA+T is a precision, high-side current-sense amplifier designed for applications requiring wide input voltage ranges, such as automotive, industrial, and power management systems. It provides an amplified output proportional to the voltage across an external sense resistor.  

### **Features:**  
- Wide input common-mode voltage range (4.5V to 76V)  
- Low quiescent current (300µA typical)  
- Rail-to-rail output swing  
- High accuracy (±1.5% max error)  
- Fixed gain options (20V/V, 60V/V, 100V/V)  
- Small µMAX package for space-constrained applications  
- Robust performance over extended temperature range (-40°C to +125°C)  

This device is suitable for battery monitoring, motor control, and power supply current sensing.
