Description and Introduction

Filterless 2-W Class-D Audio Power Amp The TPA2000D2 is a Class-D stereo audio power amplifier manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features based on factual information from TI's knowledge base:

### **Specifications:**
- **Output Power:**  
  - 1.1W per channel into 8Ω at 5V (THD+N = 10%)  
  - 2W per channel into 4Ω at 5V (THD+N = 10%)  
- **Supply Voltage Range:** 2.5V to 5.5V  
- **Efficiency:** Up to 87% (reduces power dissipation)  
- **THD+N (Total Harmonic Distortion + Noise):**  
  - Typically 0.2% (1kHz, 1W into 4Ω)  
- **Signal-to-Noise Ratio (SNR):** 93dB (A-weighted)  
- **Quiescent Current:** 2.3mA (typical)  
- **Shutdown Current:** 0.1μA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
- The TPA2000D2 is a **monolithic, filter-free, Class-D** stereo audio amplifier designed for portable applications.  
- It uses **PWM (Pulse Width Modulation)** modulation to drive speakers directly without requiring external LC output filters.  
- Features **low EMI (Electromagnetic Interference)** due to spread-spectrum modulation.  
- Includes **short-circuit and thermal protection** for reliability.  
- Optimized for **battery-powered devices** such as smartphones, portable media players, and tablets.  

### **Features:**  
- **Filterless Class-D Operation** (eliminates need for external inductors)  
- **Low Quiescent Current** (extends battery life)  
- **Spread-Spectrum Modulation** (reduces EMI)  
- **Thermal and Short-Circuit Protection**  
- **Shutdown Mode** (ultra-low leakage current)  
- **Space-Saving Package:** 20-pin TSSOP (PowerPAD™)
