Description and Introduction

8W+8W+15W TRIPLE AMPLIFIER The TDA7497S is a Class-D audio amplifier manufactured by STMicroelectronics (ST).  

### **Specifications:**  
- **Output Power:**  
  - 25W per channel (stereo) into 8Ω at 10% THD with 24V supply  
  - 15W per channel (stereo) into 8Ω at 10% THD with 18V supply  
- **Supply Voltage Range:** 10V to 26V  
- **Efficiency:** Up to 90% (typical for Class-D amplifiers)  
- **THD+N (Total Harmonic Distortion + Noise):** <0.5% (typical at 1W, 8Ω)  
- **Signal-to-Noise Ratio (SNR):** >90dB (A-weighted)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** Multiwatt15 (through-hole)  

### **Descriptions:**  
The TDA7497S is a dual BTL (Bridge-Tied Load) Class-D audio amplifier designed for high-efficiency applications such as home audio systems, TVs, and multimedia speakers. It integrates PWM modulation and output power stages, requiring minimal external components.  

### **Features:**  
- **Dual BTL Class-D Amplifier:** Provides stereo output without needing external output filters.  
- **Standby and Mute Functions:** Allows power-saving modes.  
- **Short-Circuit Protection:** Includes thermal overload and overcurrent protection.  
- **Low External Component Count:** Simplifies PCB design.  
- **Pop-Free Operation:** Minimizes noise during power-on/off.  
- **Differential Inputs:** Reduces common-mode noise.  

This information is based on the official STMicroelectronics datasheet for the TDA7497S.
