Description and Introduction

10-W Stereo Class-D Audio Power Amplifier (TPA3101) 48-HTQFP -40 to 85 The TPA3101D2PHPR is a stereo Class-D audio amplifier from Texas Instruments (TI). Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Power:**  
  - 10W per channel into 4Ω at 10% THD+N (12V supply)  
  - 15W per channel into 3Ω at 10% THD+N (12V supply)  
  - 25W into 3Ω in mono BTL mode (12V supply)  
- **Supply Voltage Range:** 4.5V to 14V  
- **Efficiency:** Up to 90%  
- **THD+N (Total Harmonic Distortion + Noise):** 0.1% (typical)  
- **Signal-to-Noise Ratio (SNR):** 100dB (A-weighted)  
- **Switching Frequency:** Adjustable (300kHz to 500kHz)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** HTSSOP-32 (PowerPAD™)  

### **Descriptions:**  
The TPA3101D2PHPR is a high-efficiency Class-D amplifier designed for driving stereo speakers in applications like LCD TVs, soundbars, and portable audio systems. It integrates a modulation scheme to minimize EMI and supports single-ended or differential inputs.  

### **Features:**  
- **Integrated Feedback:** Reduces external component count.  
- **Short-Circuit & Thermal Protection:** Enhances reliability.  
- **Adjustable Gain:** 20dB, 26dB, or 32dB settings.  
- **Pop & Click Suppression:** Minimizes noise during power-up/down.  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **Mono Bridged (BTL) Mode:** Supports higher power output.  
- **Spread-Spectrum Modulation:** Reduces EMI interference.  

This information is based solely on TI's official datasheet for the TPA3101D2PHPR.
