- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The LT1990CS8 is a high-side current sense amplifier that accurately measures current flow in a wide range of applications. It operates with a high common-mode voltage range and provides a fixed gain for converting small sense voltages into measurable output signals.  

### **Features:**  
- High common-mode voltage range (0V to 44V)  
- Low offset voltage for high accuracy  
- Fixed gain options (10, 20, 50, 100)  
- Wide supply voltage range (2.7V to 44V)  
- Low quiescent current (500µA)  
- Rail-to-rail output swing  
- Stable with capacitive loads up to 500pF  
- Suitable for automotive, industrial, and power management applications  

This device is commonly used in battery monitoring, motor control, and power supply current sensing applications.
