Description and Introduction

2W+2W AMPLIFIER WITH DC VOLUME CONTROL The TDA7496L is a class-D audio amplifier IC manufactured by STMicroelectronics (ST). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Output Power:**  
  - 50W + 50W (stereo) into 4Ω at 21V, THD = 10%  
  - 30W + 30W (stereo) into 8Ω at 21V, THD = 10%  
- **Supply Voltage Range:** 8V to 26V  
- **Efficiency:** Up to 90% (typical for class-D amplifiers)  
- **THD+N (Total Harmonic Distortion + Noise):** 0.1% (typical at 1W, 8Ω)  
- **Signal-to-Noise Ratio (SNR):** >95dB (A-weighted)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** PowerSO-36 (HSOP36)  

### **Descriptions:**
- The TDA7496L is a dual BTL (Bridge-Tied Load) class-D audio amplifier designed for high-efficiency applications.  
- It integrates PWM modulation and output power stages, requiring minimal external components.  
- Suitable for home audio systems, multimedia speakers, and compact audio amplifiers.  

### **Features:**
- **Dual-channel class-D amplifier**  
- **Standby and mute functions** for power management  
- **Short-circuit and thermal protection** for reliability  
- **Pop-free start-up and shutdown**  
- **Low external component count** (minimal filtering required)  
- **Fixed gain (30dB)** for simplified design  
- **High efficiency** reduces heat dissipation  

This information is based on STMicroelectronics' official datasheet for the TDA7496L.
