Description and Introduction

0.3-W Stereo Audio Power Amplifier The TPA302 is a Class-D audio amplifier from Texas Instruments (TI). Here are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Output Power:**  
  - 20W per channel into 4Ω at 10% THD+N (VDD = 15V)  
  - 15W per channel into 8Ω at 10% THD+N (VDD = 15V)  
- **Supply Voltage Range (VDD):** 4.5V to 26V  
- **Efficiency:** Up to 90% (Class-D operation)  
- **THD+N (Total Harmonic Distortion + Noise):** Typically 0.1% (1W, 1kHz)  
- **Signal-to-Noise Ratio (SNR):** >100dB (A-weighted)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 32-pin HTSSOP (PowerPAD™)  

### **Descriptions:**  
- The TPA302 is a stereo Class-D audio amplifier designed for high-efficiency audio applications.  
- It uses a fixed-gain architecture, eliminating the need for external gain-setting resistors.  
- Features built-in protection circuits, including over-temperature, under-voltage, and over-current protection.  
- Suitable for consumer audio applications such as TVs, soundbars, and portable speakers.  

### **Features:**  
- **Class-D Operation:** High efficiency with low heat dissipation.  
- **Fixed Gain (20dB):** Simplifies design by eliminating external components.  
- **Differential Inputs:** Reduces common-mode noise.  
- **Pop-and-Click Suppression:** Minimizes audible noise during power-up/down.  
- **Short-Circuit Protection:** Prevents damage from output shorts.  
- **Thermal Shutdown:** Protects the device from overheating.  
- **Low Quiescent Current:** Enhances power efficiency in standby mode.  

This information is strictly based on the available technical data for the TPA302 from Texas Instruments.
