- **Gain Bandwidth Product:** 3 MHz (typ)  
- **Output Current:** 20 mA (min)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
- The TDA7278 is a monolithic dual operational amplifier designed for general-purpose applications.  
- It features low noise, high gain, and wide bandwidth, making it suitable for audio, instrumentation, and signal conditioning circuits.  
- The device is internally compensated for unity-gain stability.  

### **Features:**  
- **Dual Op-Amp Configuration:** Two independent amplifiers in a single package.  
- **Low Noise:** Suitable for high-fidelity audio applications.  
- **Wide Supply Voltage Range:** Operates from ±3V to ±18V.  
- **Short-Circuit Protection:** Built-in protection against output short circuits.  
- **Low Power Consumption:** Ideal for battery-operated devices.  
- **Internal Frequency Compensation:** Ensures stability without external components.  

The TDA7278 is available in an 8-pin DIP or SOIC package.
