Description and Introduction

25 + 25W STEREO AMPLIFIER WITH MUTE/ST-BY The TDA7264 is a dual bridge amplifier manufactured by STMicroelectronics (ST). Below are the specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Type:** Dual Bridge Amplifier  
- **Output Power:**  
  - 15W per channel (into 8Ω at THD = 10%, VS = ±12V)  
  - 7W per channel (into 4Ω at THD = 10%, VS = ±8V)  
- **Supply Voltage Range (VS):** ±5V to ±15V  
- **Operating Voltage Range:** 10V to 30V (split supply)  
- **Total Harmonic Distortion (THD):** 0.5% (typical at 1W, 1kHz)  
- **Signal-to-Noise Ratio (SNR):** 85dB (typical)  
- **Quiescent Current:** 50mA (typical)  
- **Gain:** 30dB (fixed)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** Multiwatt15 (15-pin)  

### **Descriptions:**  
The TDA7264 is a dual bridge amplifier designed for high-quality audio applications such as stereo TV sound systems, home stereos, and multimedia speakers. It operates in Class AB mode and features built-in thermal shutdown and short-circuit protection.  

### **Features:**  
- Dual bridge configuration (two independent amplifiers)  
- Mute and standby functions  
- No external components required for mute/standby  
- Low noise and distortion  
- Thermal overload protection  
- Short-circuit protection  
- High output power capability  
- ESD protection  

This information is based on the manufacturer's datasheet for the TDA7264 by STMicroelectronics.

Application Scenarios & Design Considerations

25 + 25W STEREO AMPLIFIER WITH MUTE/ST-BY

Alternative Part Number

  • LM1875T --: Class AB audio power amplifier in TO-220 package with comparable output power and supply range, widely used as a drop-in substitute for TDA7264 in audio applications.
  • TDA2030A --: Similar 14W class AB audio amplifier with the same pinout family and supply voltage range, commonly used as a replacement in low-power audio designs.
  • TDA2050 --: Higher-power class AB audio amplifier in the same TDA series with compatible supply and pin configuration, suitable when slightly more output power is acceptable.
