Description and Introduction

35V; V(in): 8V; 16W; 5W+5W amplifier with DC volume control The TDA7496SA is a class-D audio amplifier manufactured by PH (likely referring to Philips or NXP Semiconductors, as they historically produced TDA-series ICs).  

### **Specifications:**  
- **Output Power:** 15W per channel (stereo) into 8Ω at 18V (typical).  
- **Supply Voltage Range:** 8V to 26V.  
- **Efficiency:** Up to 90% (typical for class-D amplifiers).  
- **THD+N (Total Harmonic Distortion + Noise):** Low distortion levels (specific value depends on operating conditions).  
- **Standby Current:** Low quiescent current for power-saving operation.  
- **Thermal Protection:** Built-in thermal shutdown to prevent overheating.  
- **Short-Circuit Protection:** Safeguards against output shorts.  

### **Descriptions:**  
- The TDA7496SA is a stereo class-D amplifier designed for efficient audio amplification in compact applications.  
- It operates in bridge-tied load (BTL) configuration, eliminating the need for output coupling capacitors.  
- Suitable for multimedia speakers, portable audio devices, and other low-to-medium power audio systems.  

### **Features:**  
- **Class-D Operation:** High efficiency with minimal heat dissipation.  
- **Mute Function:** Allows muting the amplifier when not in use.  
- **Standby Mode:** Reduces power consumption when idle.  
- **Minimal External Components:** Simplifies PCB design and reduces BOM cost.  
- **Surface-Mount Package:** Typically comes in a HSOP-36 package for compact designs.
