Description and Introduction

120V-100W DMOS AUDIO AMPLIFIER WITH MUTE/ST-BY The TDA7293 is a monolithic integrated circuit (IC) manufactured by STMicroelectronics (ST). It is designed as a high-performance audio amplifier in a Multiwatt15 package.  

### **Specifications:**  
- **Output Power:**  
  - 100W RMS into 8Ω at ±40V supply  
  - 120W RMS into 8Ω at ±45V supply (with 10% THD)  
- **Supply Voltage Range:** ±12V to ±50V  
- **Operating Voltage Range:** ±10V to ±40V (recommended for safe operation)  
- **Output Current:** 10A (peak)  
- **Total Harmonic Distortion (THD):** 0.1% (typical at 1kHz, 50W, 8Ω)  
- **Signal-to-Noise Ratio (SNR):** > 95dB  
- **Input Sensitivity:** 1.35V RMS for full output  
- **Gain:** 30dB (adjustable via external resistors)  
- **Standby & Mute Functions:** Yes (low-power consumption modes)  
- **Package:** Multiwatt15 (15-pin vertical power package)  

### **Descriptions:**  
The TDA7293 is a class AB audio amplifier IC optimized for high-power audio applications. It features DMOS power stages for improved efficiency and thermal stability. It includes built-in protection circuits against short-circuits, thermal overload, and overvoltage.  

### **Features:**  
- **High Output Power:** Up to 120W into 8Ω  
- **DMOS Power Stage:** Low distortion and high efficiency  
- **Mute & Standby Functions:** Allows power-saving modes  
- **Short-Circuit Protection:** Built-in safeguards  
- **Thermal Shutdown:** Prevents overheating  
- **Flexible Supply Range:** Supports wide voltage inputs  
- **No External Compensation Required:** Simplified design  

This IC is commonly used in high-fidelity audio amplifiers, home theater systems, and professional audio equipment.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • LM3886TF --: Class AB audio power amplifier in an isolated TO-220 package with comparable output power and supply range, widely used as a direct substitute in audio amplifier designs.
  • TDA7294 --: Same DMOS audio amplifier family with nearly identical pinout and supply voltage range, offering slightly lower output power but very close electrical behavior.
  • LM3876T --: Similar high-voltage audio power amplifier with comparable gain and output capability, suitable for equivalent audio amplifier applications.
