Description and Introduction

32W BRIDGE CAR RADIO AMPLIFIER The TDA7391PD is a class-AB audio amplifier IC manufactured by STMicroelectronics (STM).  

### **Specifications:**  
- **Output Power:** 10W per channel (at 10% THD, 4Ω, 14.4V)  
- **Operating Voltage:** 8V to 18V  
- **Quiescent Current:** 80mA (typical)  
- **Total Harmonic Distortion (THD):** 0.1% (typical at 1W, 4Ω)  
- **Signal-to-Noise Ratio (SNR):** 85dB (typical)  
- **Package:** PowerSO-20 (multiwatt)  
- **Number of Channels:** 2 (stereo)  
- **Standby Function:** Yes (low-power mode)  
- **Mute Function:** Yes  

### **Descriptions:**  
The TDA7391PD is a dual-bridge audio amplifier designed for car radio applications. It provides high output power with low distortion and features built-in protection circuits against short circuits, thermal overload, and overvoltage.  

### **Features:**  
- High output power capability  
- Low distortion and noise  
- Standby and mute functions  
- Short-circuit and thermal protection  
- Overvoltage protection  
- Flexible supply voltage range (8V to 18V)  
- No external bootstrap capacitors required  

This IC is commonly used in automotive audio systems and other applications requiring reliable stereo amplification.
