Description and Introduction

Mono, Medium Power, Filter-Free Class-D Audio Amplifier The TPA3007D1PWR is a Class-D audio amplifier manufactured by Texas Instruments (TI). Here are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Package:** TSSOP-28 (PBF - Lead-Free)  
- **Output Power:** Up to 7W per channel into 4Ω (at 10% THD+N, 12V supply)  
- **Supply Voltage Range:** 4.5V to 18V  
- **Efficiency:** Up to 90% (Class-D operation)  
- **Total Harmonic Distortion + Noise (THD+N):** <0.3% (typical)  
- **Signal-to-Noise Ratio (SNR):** 90dB (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Output Configuration:** Stereo (2-channel)  
- **Switching Frequency:** 250kHz (typical)  

### **Descriptions:**  
The TPA3007D1PWR is a Class-D stereo audio amplifier designed for efficient, high-quality audio amplification in portable and low-power applications. It integrates a modulation scheme that reduces electromagnetic interference (EMI) while delivering clear sound output.  

### **Features:**  
- **Class-D Operation:** High efficiency with minimal heat dissipation.  
- **Integrated Feedback:** Reduces output filter requirements.  
- **Short-Circuit & Thermal Protection:** Enhances reliability.  
- **Low Quiescent Current:** ~4mA (typical) for power-saving operation.  
- **Pop & Click Suppression:** Minimizes noise during power-up/down.  
- **Single-Supply Operation:** Simplifies power requirements.  
- **Small Footprint:** TSSOP-28 package for space-constrained designs.  

This amplifier is commonly used in battery-powered audio systems, LCD TVs, portable speakers, and other consumer electronics.
