Description and Introduction

10W AMPLIFIER The TDA7494/S is a class-D audio amplifier manufactured by STMicroelectronics (STM). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Output Power:**  
  - 50W + 50W (stereo) at 4Ω, THD = 10%  
  - 30W + 30W (stereo) at 8Ω, THD = 10%  
- **Supply Voltage Range:** ±10V to ±25V  
- **Efficiency:** Up to 90% (typical for class-D amplifiers)  
- **THD (Total Harmonic Distortion):** < 0.5% (typical)  
- **Signal-to-Noise Ratio (SNR):** > 90dB  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** Multiwatt15 (through-hole)  

### **Description:**  
The TDA7494/S is a dual BTL (Bridge-Tied Load) class-D audio amplifier designed for high-efficiency audio applications. It integrates PWM modulation and output power stages, making it suitable for compact and efficient audio systems such as home stereos, TVs, and multimedia speakers.  

### **Features:**  
- **Dual BTL Class-D Amplifier:** Provides two independent channels.  
- **High Efficiency:** Reduces heat dissipation and power consumption.  
- **Standby and Mute Functions:** Allows power-saving modes.  
- **Short-Circuit and Thermal Protection:** Enhances reliability.  
- **Low External Component Count:** Simplifies PCB design.  
- **Wide Supply Voltage Range:** Supports flexible power supply configurations.
