Description and Introduction

100W+100W dual BTL Class-D audio amplifier The TDA7498 is a class-D audio amplifier manufactured by STMicroelectronics. Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Output Power:**  
  - 100W + 100W (4Ω, THD = 10%)  
  - 70W + 70W (8Ω, THD = 10%)  
- **Supply Voltage Range:** ±10V to ±25V  
- **Efficiency:** Up to 90%  
- **THD+N (Total Harmonic Distortion + Noise):** 0.1% (typical at 1W, 8Ω)  
- **Signal-to-Noise Ratio (SNR):** >100dB  
- **Frequency Response:** 20Hz - 20kHz  
- **Standby Current:** <1mA  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The TDA7498 is a dual BTL (Bridge-Tied Load) class-D amplifier with high efficiency, designed for audio applications such as home theater systems, active speakers, and professional audio equipment. It integrates PWM modulation and protection features, reducing external component count.  

### **Features:**  
- **Dual-channel Class-D Amplifier**  
- **Mute and Standby Functions**  
- **Short-Circuit Protection**  
- **Thermal Overload Protection**  
- **Clip Detection**  
- **Low External Component Count**  
- **Surface-Mount Package (PowerSO-36)**  

This information is based solely on the manufacturer's datasheet.

Description and Introduction

100W+100W dual BTL Class-D audio amplifier The TDA7498 is a class-D audio amplifier manufactured by SGS-THOMSON (now STMicroelectronics). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Output Power:**  
  - 100W per channel (stereo) into 4Ω at 10% THD, ±30V supply.  
  - 70W per channel (stereo) into 8Ω at 10% THD, ±30V supply.  
- **Supply Voltage Range:** ±10V to ±30V (dual supply).  
- **Total Harmonic Distortion (THD):** Typically 0.1% at 1W, 1kHz.  
- **Signal-to-Noise Ratio (SNR):** >100dB (A-weighted).  
- **Efficiency:** Up to 90% (class-D operation).  
- **Operating Frequency:** Switching frequency ~300kHz.  
- **Package:** PowerDIP20 (multiwatt-15).  

### **Descriptions:**  
- The TDA7498 is a high-performance class-D amplifier designed for high-power audio applications.  
- It operates in BTL (Bridge-Tied Load) configuration, eliminating the need for output coupling capacitors.  
- Features built-in protection circuits for over-temperature, short-circuit, and over-voltage conditions.  

### **Features:**  
- **High Output Power:** Capable of delivering up to 100W per channel.  
- **Low Distortion:** Minimal THD for high-fidelity audio.  
- **Mute & Standby Functions:** Allows power-saving modes.  
- **Thermal Protection:** Auto-shutdown in case of overheating.  
- **Short-Circuit Protection:** Safeguards the amplifier from damage.  
- **Wide Supply Voltage Range:** Supports flexible power supply configurations.  

The TDA7498 is commonly used in home audio systems, powered speakers, and professional amplifiers.
