Description and Introduction

DUAL BRIDGE AUDIO AMPLIFIER FOR CAR RADIO The TDA7374 is a quad bridge car radio amplifier manufactured by STMicroelectronics. Here are its specifications, descriptions, and features:

### **Specifications:**
- **Power Supply Voltage (Vs):** 8V to 18V  
- **Output Power (Po):**  
  - 4 x 6W (max) @ 14.4V, 4Ω, 10% THD  
  - 4 x 4W (typ) @ 14.4V, 4Ω, 1% THD  
- **Operating Temperature Range:** -40°C to +105°C  
- **Standby Current (Iq):** < 100µA  
- **Total Harmonic Distortion (THD):** 0.1% (typ) @ 1W, 1kHz  
- **Signal-to-Noise Ratio (SNR):** 90dB (typ)  

### **Descriptions:**
- The TDA7374 is a monolithic integrated circuit designed for car radio applications.  
- It features four independent bridge amplifiers, making it suitable for 4-channel audio systems.  
- The device includes protection circuits against short circuits, thermal overload, and overvoltage.  
- It operates in a single power supply configuration, simplifying system design.  

### **Features:**
- **Quad Bridge Amplifier:** Four independent BTL (Bridge-Tied Load) outputs.  
- **Low Standby Current:** Enables energy-efficient operation.  
- **Mute & Standby Functions:** Allows power-saving modes.  
- **Short-Circuit Protection:** Safeguards the amplifier and speakers.  
- **Thermal Shutdown:** Prevents damage from overheating.  
- **Minimal External Components:** Reduces PCB footprint and cost.  
- **High Output Power Capability:** Suitable for car audio applications.  

The TDA7374 is commonly used in automotive audio systems due to its robustness and performance.

- The device includes built-in protection circuits against short circuits, overvoltage, and thermal overload.  

### **Features:**  
- **Quad BTL Output Configuration**  
- **Mute and Standby Functions**  
- **No External Components Needed for Operation**  
- **Low External Component Count**  
- **Short-Circuit and Thermal Protection**  
- **High Output Power Capability**  
- **Improved EMI Performance**  

This amplifier is commonly used in automotive audio systems due to its efficiency and robust design.
