Description and Introduction

Stereo, Low Power, Wide Supply Voltage, Filter-Free Class-D Audio Amplifier The TPA3003D2PFBR is a Class-D audio amplifier manufactured by Texas Instruments. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TEXAS)  
- **Type:** Class-D Stereo Audio Power Amplifier  
- **Output Power:**  
  - 10W per channel into 4Ω at 10% THD+N (VDD = 15V)  
  - 6W per channel into 8Ω at 10% THD+N (VDD = 15V)  
- **Supply Voltage Range (VDD):** 8V to 16V  
- **Efficiency:** Up to 90%  
- **THD+N (Total Harmonic Distortion + Noise):** 0.2% (typical at 1W, 8Ω)  
- **Signal-to-Noise Ratio (SNR):** 95dB (A-weighted)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 48-pin HTSSOP (PowerPAD™)  

### **Descriptions:**  
- The TPA3003D2PFBR is a high-efficiency, stereo Class-D audio amplifier designed for driving speakers in applications such as LCD TVs, monitors, and multimedia systems.  
- It integrates a modulation scheme to reduce electromagnetic interference (EMI).  
- Features differential inputs to minimize noise pickup.  
- Includes built-in protection circuits for overcurrent, undervoltage, and thermal shutdown.  

### **Features:**  
- **High Efficiency:** Reduces power dissipation and heat generation.  
- **Differential Inputs:** Improves noise rejection.  
- **Adjustable Gain:** Configurable via external resistors.  
- **Pop and Click Suppression:** Minimizes audible noise during power-up/down.  
- **Short-Circuit and Thermal Protection:** Enhances reliability.  
- **Low External Component Count:** Simplifies PCB design.  

This information is strictly based on the manufacturer's datasheet and technical documentation.
