Description and Introduction

35W BRIDGE CAR RADIO AMPLIFIER The TDA7391 is a car radio amplifier manufactured by STMicroelectronics. Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Type:** Class AB Audio Amplifier  
- **Output Power:**  
  - 4 x 25W (4Ω, 14.4V, THD = 10%)  
  - 4 x 15W (4Ω, 12V, THD = 10%)  
- **Supply Voltage Range:** 8V to 18V  
- **Operating Voltage:** 6V to 18V  
- **Standby Current:** < 100µA  
- **Load Impedance:** 4Ω  
- **Total Harmonic Distortion (THD):** 0.1% (typical at 1W, 1kHz)  
- **Signal-to-Noise Ratio (SNR):** > 85dB  
- **Package:** PowerSO-36  

### **Descriptions:**  
The TDA7391 is a quad bridge car radio amplifier designed for high-quality audio output in automotive applications. It features built-in diagnostics and protection circuits, including short-circuit, thermal shutdown, and overvoltage protection.  

### **Features:**  
- **Quad Bridge Configuration:** Allows for four independent channels.  
- **Mute & Standby Functions:** Low power consumption in standby mode.  
- **Diagnostic Output:** Provides fault detection (short-circuit, over-temperature).  
- **Thermal Protection:** Prevents overheating damage.  
- **High Output Power Capability:** Suitable for car audio systems.  
- **Low External Component Count:** Simplifies circuit design.  

This information is based on the manufacturer's datasheet. For detailed technical parameters, refer to the official STMicroelectronics documentation.
