Description and Introduction

Quad BTL output power amplifier with stand-by and mute inputs, clip and offset detections The TDA7388A is a quad bridge car radio amplifier manufactured by STMicroelectronics.  

### **Specifications:**  
- **Output Power:** 4 x 41W (max) at 14.4V, 1kHz, 10% THD, 4Ω  
- **Operating Voltage Range:** 6V to 18V  
- **Standby Current:** <100µA  
- **Mute Function:** Yes  
- **Standby Function:** Yes  
- **Thermal Protection:** Yes  
- **Short-Circuit Protection:** Yes  
- **Package:** Flexiwatt 25 (multiwatt15)  

### **Description:**  
The TDA7388A is a Class-AB audio amplifier designed for car radio applications. It features four independent amplifier channels, making it suitable for multi-speaker systems. The device includes built-in protection against short circuits, thermal overload, and DC offset detection.  

### **Features:**  
- **High Output Power:** Capable of delivering up to 41W per channel.  
- **Low Distortion:** Ensures high-quality audio reproduction.  
- **Standby & Mute Modes:** Reduces power consumption when not in use.  
- **Clip Detector:** Provides an output signal when distortion occurs.  
- **Flexiwatt Package:** Facilitates efficient heat dissipation.  
- **Wide Supply Voltage Range:** Supports operation in various automotive conditions.  

This amplifier is commonly used in car audio systems due to its robust performance and protection features.
