Description and Introduction

6 + 6W STEREO AMPLIFIER WITH MUTE & ST-BY The TDA7499 is a class-D audio amplifier manufactured by STMicroelectronics. Below are the factual details from Ic-phoenix technical data files:

### **Specifications:**  
- **Output Power:**  
  - 100W per channel (4Ω, THD = 10%)  
  - 160W (BTL mode, 8Ω, THD = 10%)  
- **Supply Voltage Range:** 10V to 36V  
- **Efficiency:** Up to 90%  
- **THD+N (Total Harmonic Distortion + Noise):** < 0.1% (typical)  
- **Signal-to-Noise Ratio (SNR):** > 100dB  
- **Operating Frequency:** 300kHz to 500kHz (adjustable)  
- **Standby Current:** < 1mA  
- **Mute Function:** Yes  
- **Thermal Protection:** Yes  
- **Short-Circuit Protection:** Yes  

### **Descriptions:**  
- The TDA7499 is a dual BTL (Bridge-Tied Load) class-D amplifier designed for high-power audio applications.  
- It operates in a single-ended supply configuration, making it suitable for consumer audio systems, home theaters, and professional amplifiers.  
- The device includes built-in protection features such as thermal shutdown and short-circuit protection.  

### **Features:**  
- **High Efficiency:** Class-D operation reduces power dissipation.  
- **Flexible Supply Voltage:** Works across a wide input range (10V–36V).  
- **Adjustable Switching Frequency:** Allows optimization for EMI performance.  
- **Standby and Mute Modes:** Low-power consumption when inactive.  
- **Minimal External Components:** Simplifies PCB design.  
- **Surface-Mount Package:** HTSSOP32 (PowerSSO-36) for compact designs.
