Description and Introduction

2 x 30WDUAL/QUAD POWER AMPLIFIER FOR CAR RADIO The TDA7377H is a dual bridge amplifier manufactured by STMicroelectronics (STM). Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Output Power:**  
  - 2 x 30W (max) @ 4Ω, 14.4V, 10% THD  
  - 2 x 22W (max) @ 4Ω, 14.4V, 1% THD  
  - 2 x 15W (max) @ 8Ω, 14.4V, 10% THD  
- **Supply Voltage Range:** 8V to 18V  
- **Operating Voltage:** 14.4V (typical)  
- **Quiescent Current:** 80mA (typical)  
- **Total Harmonic Distortion (THD):** 0.1% (typical) @ 1W, 4Ω  
- **Signal-to-Noise Ratio (SNR):** 95dB (typical)  
- **Frequency Response:** 20Hz - 20kHz  
- **Gain:** 26dB (fixed)  
- **Package:** Multiwatt15V (15-pin vertical power package)  

### **Description:**  
The TDA7377H is a dual bridge audio amplifier designed for car radio applications. It provides high output power with low distortion and features built-in protection circuits, including short-circuit and thermal protection.  

### **Features:**  
- **Dual Bridge Configuration:** Allows for stereo or mono (BTL) operation.  
- **Standby/Mute Function:** Reduces power consumption when not in use.  
- **Short-Circuit Protection:** Safeguards the amplifier and speakers.  
- **Thermal Shutdown:** Prevents overheating.  
- **Low External Component Count:** Simplifies PCB design.  
- **High Output Power:** Suitable for car audio systems.  
- **Pop & Click Suppression:** Minimizes noise during power-on/off.  

This information is based on the manufacturer's datasheet. For detailed technical parameters, refer to the official STMicroelectronics documentation.
