- **Package Options:** PDIP-8, SOIC-8  

### **Descriptions:**  
- The TL082B is a low-noise, high-speed JFET-input operational amplifier.  
- It features low input bias and offset currents, making it suitable for high-impedance applications.  
- The device is internally compensated for stable operation.  
- It is designed for use in precision analog circuits, audio applications, and signal conditioning.  

### **Features:**  
- **JFET-Input:** Provides high input impedance and low input bias current.  
- **Low Noise:** Suitable for sensitive signal processing.  
- **Wide Bandwidth:** 3 MHz gain bandwidth product.  
- **High Slew Rate:** 13 V/µs for fast signal response.  
- **Low Power Consumption:** Ideal for battery-operated devices.  
- **High CMRR and PSRR:** Ensures stable performance in noisy environments.  
- **Dual Operational Amplifier:** Two independent op-amps in a single package.  

The TL082B is commonly used in audio amplifiers, active filters, integrators, and other precision analog circuits.
