Description and Introduction

2 x 35W POWER AMPLIFIER FOR CAR RADIO The TDA7376B is a car radio amplifier manufactured by STMicroelectronics (ST).  

### **Specifications:**  
- **Type:** Quad Bridge Car Radio Amplifier  
- **Output Power:**  
  - 4 x 25W @ 4Ω, 14.4V, 1kHz, 10% THD  
  - 4 x 11W @ 4Ω, 14.4V, 1kHz, 1% THD  
- **Operating Voltage:** 8V to 18V  
- **Standby Current:** < 100µA  
- **Mute Current:** < 1mA  
- **Total Harmonic Distortion (THD):** 0.03% (typical at 1W, 1kHz)  
- **Signal-to-Noise Ratio (SNR):** > 90dB  
- **Package:** PowerSO-20 (multiwatt)  

### **Descriptions:**  
The TDA7376B is a quad bridge amplifier designed for car radio applications. It features four independent channels with high output power capability and low distortion. The device includes built-in protection circuits (short-circuit, thermal shutdown, and overvoltage protection) for reliable operation in automotive environments.  

### **Features:**  
- **Quad Bridge Configuration:** Allows flexible speaker connections.  
- **Standby & Mute Functions:** Low power consumption when inactive.  
- **DC Offset Detection:** Protects speakers from DC voltage.  
- **Clip Detector Output:** Indicates signal distortion.  
- **Low External Component Count:** Simplifies PCB design.  
- **Thermal Protection:** Prevents overheating damage.  
- **Short-Circuit Protection:** Safeguards the amplifier outputs.  

This information is based on STMicroelectronics' official datasheet for the TDA7376B.
