Description and Introduction

80 W + 80 W dual BTL class-D audio amplifier The TDA7498L is a class-D audio amplifier manufactured by STMicroelectronics (ST).  

### **Specifications:**  
- **Output Power:**  
  - 100W + 100W (4Ω, THD = 10%)  
  - 50W + 50W (8Ω, THD = 10%)  
- **Supply Voltage Range:** 10V to 36V  
- **Efficiency:** Up to 90%  
- **Signal-to-Noise Ratio (SNR):** > 95dB  
- **Total Harmonic Distortion + Noise (THD+N):** < 0.1% (1W, 8Ω)  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package:** PowerSO36  

### **Descriptions:**  
- The TDA7498L is a dual BTL (Bridge-Tied Load) class-D amplifier with high efficiency.  
- It features built-in protection circuits, including thermal shutdown, overcurrent, and undervoltage protection.  
- The amplifier operates in a single-ended configuration, simplifying PCB design.  

### **Features:**  
- **High Power Output:** Capable of driving up to 100W per channel into 4Ω loads.  
- **Wide Supply Voltage Range:** Supports operation from 10V to 36V.  
- **Standby and Mute Functions:** Allows power-saving modes.  
- **Short-Circuit Protection:** Ensures reliability in fault conditions.  
- **Minimal External Components:** Reduces system cost and complexity.  
- **Thermal Protection:** Prevents overheating damage.  

This information is based on the manufacturer's datasheet for the TDA7498L.
