Description and Introduction

15-W Stereo Class-D Audio Power Amplifier (TPA3107) The TPA3107D2 is a stereo Class-D audio amplifier manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Output Power:**  
  - 20W per channel into 4Ω at 10% THD+N (VDD = 21V)  
  - 15W per channel into 8Ω at 10% THD+N (VDD = 21V)  
- **Supply Voltage Range (VDD):** 4.5V to 26V  
- **Efficiency:** Up to 90%  
- **THD+N (Total Harmonic Distortion + Noise):** 0.1% (typical at 1W, 8Ω)  
- **Signal-to-Noise Ratio (SNR):** 95dB (A-weighted)  
- **Switching Frequency:** 300kHz to 500kHz (adjustable)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 32-pin HTSSOP (PowerPAD™)  

### **Descriptions:**  
The TPA3107D2 is a high-efficiency Class-D audio amplifier designed for stereo applications. It integrates a modulation scheme to reduce EMI and supports a wide voltage range, making it suitable for consumer audio systems like soundbars, TVs, and portable speakers.  

### **Features:**  
- **Class-D Operation:** High efficiency with minimal heat dissipation.  
- **Adjustable Gain:** Configurable gain settings (20dB, 26dB, 32dB, 36dB).  
- **Integrated Feedback:** Reduces external component count.  
- **Short-Circuit & Thermal Protection:** Includes overcurrent and thermal shutdown.  
- **Low Standby Current:** <1µA in shutdown mode.  
- **Differential Inputs:** Reduces noise susceptibility.  
- **Pop & Click Suppression:** Minimizes audible noise during power-up/down.  
- **Spread-Spectrum Modulation:** Lowers EMI emissions.
