Description and Introduction

28W HI-FI AUDIO POWER AMPLIFIER WITH MUTE/STAND-BY The TDA7298 is a dual bridge amplifier manufactured by STMicroelectronics. Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Supply Voltage (Vs):** ±10V to ±25V  
- **Output Power:**  
  - 15W per channel (into 8Ω at ±18V, THD = 10%)  
  - 30W (into 4Ω at ±18V, THD = 10%)  
- **Operating Voltage Range:** ±6V to ±25V  
- **Quiescent Current:** 50mA (typical)  
- **Total Harmonic Distortion (THD):** 0.1% (typical at 1W, 1kHz)  
- **Signal-to-Noise Ratio (SNR):** 90dB (typical)  
- **Gain:** 32dB (fixed)  
- **Bandwidth:** 20Hz–20kHz  
- **Load Impedance:** 4Ω to 16Ω  

### **Description:**  
The TDA7298 is a dual bridge amplifier designed for high-quality audio applications such as home stereos, TVs, and multimedia systems. It integrates two independent bridge amplifiers in a single package, providing efficient and compact amplification.  

### **Features:**  
- **Dual Bridge Configuration:** Allows direct speaker connection without external coupling capacitors.  
- **Mute and Standby Functions:** Low-power consumption in standby mode.  
- **Thermal Protection:** Auto-shutdown in case of overheating.  
- **Short-Circuit Protection:** Safeguards against output shorts.  
- **Low External Component Count:** Simplifies PCB design.  
- **Package:** Multiwatt15V (through-hole)  

The TDA7298 is optimized for cost-effective, high-performance audio amplification with minimal external components.
