Description and Introduction

25 W + 25 W dual BTL class-D audio amplifier The TDA7492P is a class-D audio amplifier IC manufactured by STMicroelectronics.  

### **Specifications:**  
- **Output Power:**  
  - 25W per channel into 4Ω at 18V (THD = 10%)  
  - 15W per channel into 8Ω at 18V (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  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** PowerDIP20 (through-hole)  

### **Descriptions:**  
- The TDA7492P is a dual BTL (Bridge-Tied Load) class-D amplifier designed for high-efficiency audio applications.  
- It features built-in protection circuits, including thermal shutdown, overvoltage, and short-circuit protection.  
- The amplifier operates in a single-ended configuration, requiring minimal external components.  

### **Features:**  
- Dual-channel class-D amplifier  
- No external heatsink required due to efficient thermal performance  
- Standby and mute functions for power management  
- Pop-free start-up and shutdown  
- Short-circuit and thermal protection  
- Wide supply voltage range for flexible power supply options  

The TDA7492P is commonly used in compact audio systems, TVs, and multimedia speakers.
