Description and Introduction

Filterless 2-W Class-D Audio Power Amplifier With Stereo Headphone Drive The TPA2000D4 is a Class-D audio amplifier manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features based on factual information from TI's knowledge base:

### **Specifications:**  
- **Output Power:** 2 W per channel into 4 Ω (at 5 V supply)  
- **Supply Voltage Range:** 2.5 V to 5.5 V  
- **Efficiency:** Up to 90% (typical)  
- **THD+N (Total Harmonic Distortion + Noise):** 0.2% (typical at 1 W, 4 Ω)  
- **Quiescent Current:** 2.5 mA (typical)  
- **Shutdown Current:** 0.01 µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin HTSSOP (PowerPAD™)  

### **Descriptions:**  
The TPA2000D4 is a stereo Class-D audio amplifier designed for portable applications such as smartphones, tablets, and portable media players. It features high efficiency, low power consumption, and minimal heat generation, making it suitable for battery-powered devices.  

### **Features:**  
- **Class-D Operation:** Provides high efficiency with low power dissipation.  
- **Filterless Design:** Eliminates the need for external LC filters.  
- **Low EMI (Electromagnetic Interference):** Optimized switching output reduces noise.  
- **Thermal and Short-Circuit Protection:** Built-in safeguards for reliability.  
- **Pop & Click Suppression:** Minimizes audible noise during power-up/down.  
- **Differential Inputs:** Reduces common-mode noise interference.  
- **Shutdown Mode:** Ultra-low current consumption when inactive.
