- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-pin SOIC  

### **Descriptions:**  
The INA326EA/250 is a low-power, precision instrumentation amplifier designed for applications requiring high accuracy and rail-to-rail input/output operation. It features an innovative indirect current-feedback architecture, enabling superior performance in low-voltage and single-supply systems.  

### **Features:**  
- **Rail-to-Rail Input/Output:** Supports full dynamic range in low-voltage applications.  
- **Low Power Consumption:** Ideal for battery-operated devices.  
- **High CMRR & PSRR:** Ensures noise rejection and stability.  
- **Wide Supply Range:** Operates from ±1.35V to ±18V (dual) or 2.7V to 36V (single).  
- **Gain Set with External Resistors:** Flexible gain configuration.  
- **Low Offset Voltage & Drift:** Enhances measurement accuracy.  
- **Stable with Capacitive Loads:** Reduces need for external compensation.  

This information is strictly based on the manufacturer's datasheet and technical documentation.
