Description and Introduction

Quad BTL output power amplifier with stand-by and mute inputs The TDA7387EP is a quad bridge car radio amplifier manufactured by STMicroelectronics (ST). Here are its specifications, descriptions, and features based on factual data:

### **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:** < 1 mA  
- **Total Harmonic Distortion (THD):** < 0.5% (at 1 W, 1 kHz)  
- **Signal-to-Noise Ratio (SNR):** > 95 dB  
- **Package:** PowerSO-20 (Exposed Pad)  

### **Descriptions:**  
- The TDA7387EP is a Class-AB audio amplifier designed for car radio applications.  
- It integrates four independent amplifier channels in a single package.  
- Features built-in diagnostics for short-circuit and thermal protection.  
- Operates in a wide supply voltage range, making it suitable for automotive environments.  

### **Features:**  
- **Quad Bridge Amplifier:** Four independent channels for multi-speaker setups.  
- **Standby & Mute Functions:** Low-power consumption modes.  
- **Short-Circuit Protection:** Detects and protects against output shorts.  
- **Thermal Protection:** Shuts down when overheating is detected.  
- **Low External Component Count:** Simplifies PCB design.  
- **High Output Power Capability:** Suitable for car audio systems.  

This information is based on STMicroelectronics' official documentation for the TDA7387EP.

Application Scenarios & Design Considerations

Quad BTL output power amplifier with stand-by and mute inputs

Alternative Part Number

  • TDA7850 --: Same Flexiwatt package and pinout family, higher output power (50W vs 45W) with MOSFET output stage, widely used as a drop-in upgrade for TDA7387EP in car audio amplifiers.
  • TDA7560 --: Quad BTL car radio power amplifier in the same Flexiwatt package with compatible pinout and supply range, offering similar 4x45W output and built-in diagnostics.
  • TDA7388 --: Closely related quad bridge car audio amplifier with nearly identical electrical characteristics and Flexiwatt package, suitable as a functional substitute with minor pinout verification.
