Description and Introduction

4 X 22W FOUR BRIDGE CHANNELS CAR RADIO AMPLIFIER The TDA7382 is a quad bridge car radio amplifier manufactured by STMicroelectronics.  

### **Specifications:**  
- **Output Power:** 4 x 45 W (max) at 14.4 V, 1 kHz, 10% THD, 4 Ω  
- **Operating Voltage Range:** 8 V to 18 V  
- **Standby Current:** < 100 µA  
- **Mute Current:** < 10 mA  
- **Total Harmonic Distortion (THD):** 0.1% (typical) at 1 W, 1 kHz, 4 Ω  
- **Signal-to-Noise Ratio (SNR):** > 95 dB  
- **Package:** Flexiwatt 25 (multiwatt15)  

### **Descriptions:**  
- The TDA7382 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 circuits against short circuits, overvoltage, and thermal overload.  

### **Features:**  
- **Quad Bridge Amplifier:** Four independent channels for multi-speaker setups.  
- **High Output Power:** Capable of delivering up to 45 W per channel.  
- **Low Distortion:** Ensures high-quality audio output.  
- **Standby & Mute Functions:** Reduces power consumption when not in use.  
- **Protection Circuits:** Includes short-circuit, overvoltage, and thermal shutdown protection.  
- **Flexiwatt Package:** Facilitates efficient heat dissipation.

Application Scenarios & Design Considerations

4 X 22W FOUR BRIDGE CHANNELS CAR RADIO AMPLIFIER

Alternative Part Number

  • TDA7388 --: Same TDA738x family quad bridge power amplifier with nearly identical pinout and 4x41W output, widely used as a direct substitute in car audio head units.
  • TDA7850 --: Higher-power quad BTL car audio amplifier in the same package and pin-compatible layout, commonly used as an upgrade replacement for TDA7382.
  • TDA7560 --: Quad bridge car radio power amplifier with compatible pinout and supply range, a proven drop-in alternative when TDA7382 is unavailable.
  • TDA7384 --: Closely related ST quad bridge amplifier with the same package and pinout, providing similar 4x35W class performance as a direct functional substitute.
