Description and Introduction

120V-100W DMOS AUDIO AMPLIFIER WITH MUTE/ST-BY The TDA7293V is a monolithic integrated circuit manufactured by STMicroelectronics (ST). It is designed for use as an audio amplifier AB class, capable of delivering high output power.  

### **Specifications:**  
- **Output Power:**  
  - 100W RMS into 4Ω at ±35V  
  - 80W RMS into 8Ω at ±30V  
- **Operating Voltage Range:** ±12V to ±40V  
- **Output Current:** 10A (peak)  
- **Total Harmonic Distortion (THD):** 0.1% (typical at 1kHz, 50W, 8Ω)  
- **Signal-to-Noise Ratio (SNR):** > 95dB  
- **Frequency Response:** 20Hz – 20kHz  
- **Gain:** 30dB (fixed)  
- **Standby and Mute Functions:** Yes  
- **Thermal Protection:** Yes  
- **Short-Circuit Protection:** Yes  
- **Package:** Multiwatt15V (15-pin)  

### **Descriptions and Features:**  
- **High Power Output:** Suitable for high-fidelity audio applications.  
- **DMOS Power Stage:** Ensures low distortion and high efficiency.  
- **Mute and Standby Modes:** Allows power-saving and noise reduction.  
- **No External Components Required for Standby/Mute:** Simplifies circuit design.  
- **Thermal Shutdown Protection:** Prevents overheating.  
- **Short-Circuit Protection:** Safeguards the amplifier from damage.  
- **Wide Supply Voltage Range:** Flexible for different power supply configurations.  

The TDA7293V is commonly used in stereo systems, home theaters, and professional audio amplifiers.

Application Scenarios & Design Considerations

120V-100W DMOS AUDIO AMPLIFIER WITH MUTE/ST-BY

Alternative Part Number

  • LM3886TF --: Widely used Class AB audio power amplifier in the same power class with comparable output and thermal performance; a common drop-in style substitute for TDA7293 designs.
  • TDA7294 --: Same TDA729x family and pin-compatible package, very similar supply voltage range and output power, often used as a direct fallback when TDA7293 is unavailable.
  • LM3875TF --: Alternative high-voltage audio power amplifier with similar output power and package style, suitable for comparable audio amplifier applications.
