- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 14-Pin PDIP (Plastic Dual In-Line Package)  

### **Descriptions and Features:**  
- **Low Power Consumption:** Designed for low power operation, making it suitable for battery-powered applications.  
- **JFET Input:** Provides high input impedance and low input bias current.  
- **Wide Supply Voltage Range:** Operates from ±5V to ±18V, offering flexibility in various circuit designs.  
- **Internal Frequency Compensation:** Ensures stability without external components.  
- **High CMRR and PSRR:** Minimizes noise and interference in precision applications.  
- **Low Input Offset Voltage and Current:** Enhances accuracy in DC-coupled applications.  
- **Applications:** Used in precision integrators, sample-and-hold circuits, and low-noise signal processing.  

This amplifier is commonly used in instrumentation, audio, and control systems where low power and high input impedance are required.
