Description and Introduction

10W+10W DUAL BRIDGE AMPLIFIER The TDA7297D13TR is a dual bridge amplifier manufactured by STMicroelectronics (STM). Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Output Power:**  
  - 15W per channel (into 4Ω at 18V, THD = 10%)  
  - 7.5W per channel (into 8Ω at 18V, THD = 10%)  
- **Operating Voltage Range:** 6V to 18V  
- **Total Harmonic Distortion (THD):** 0.1% (typical)  
- **Signal-to-Noise Ratio (SNR):** 80dB  
- **Gain:** 32dB  
- **Package:** Multiwatt15V (13+2+0)  

### **Descriptions:**  
- The TDA7297D13TR is a dual bridge amplifier designed for high-quality audio applications.  
- It operates in Class AB mode, providing efficient power amplification.  
- Suitable for stereo or mono configurations in consumer electronics like TVs, home audio systems, and multimedia speakers.  

### **Features:**  
- **Dual Bridge Configuration:** Allows driving two speakers independently.  
- **Mute and Standby Functions:** Low-power consumption when inactive.  
- **Short-Circuit Protection:** Built-in safeguards against output shorts.  
- **Thermal Protection:** Prevents overheating damage.  
- **Low External Component Count:** Simplifies PCB design.  

This information is based on the manufacturer's datasheet. For detailed performance curves and application notes, refer to STMicroelectronics' official documentation.

Application Scenarios & Design Considerations

10W+10W DUAL BRIDGE AMPLIFIER

Alternative Part Number

  • LM1875T --: Class AB audio power amplifier in TO-220 package with similar output power range, widely used as a drop-in substitute for TDA7297 audio amplifier designs.
  • TDA7265 --: Dual audio power amplifier from a different ST series with comparable supply voltage and output power, suitable for similar audio applications.
  • LM4766T --: Dual 40W audio power amplifier offering comparable performance and pin-compatible style package for stereo audio amplifier designs.
  • TDA7297 --: Same audio amplifier IC family from ST; the base TDA7297 is the standard through-hole/package version and is electrically equivalent for most designs.
  • TDA7266 --: Similar ST dual-bridge audio amplifier with comparable supply voltage and output power class, usable as a functional substitute with minor pin/thermal differences.
  • LM1875 --: Widely available single-chip audio power amplifier with comparable output power range; requires circuit adaptation but is a common cross-reference for TDA7297-class amplifiers.
