Description and Introduction

0.3-W Stereo Audio Power Amplifier The TPA302D is a Class-D audio power amplifier manufactured by Texas Instruments (TI). Below are the specifications, descriptions, and features based on factual information from TI's knowledge base:  

### **Specifications:**  
- **Output Power:**  
  - 2.1 W per channel into 4 Ω at 5 V (10% THD+N)  
  - 1.4 W per channel into 8 Ω at 5 V (10% THD+N)  
- **Supply Voltage Range:** 2.5 V to 5.5 V  
- **Efficiency:** Up to 90% (Class-D operation)  
- **THD+N:** 0.2% (typical at 1 W, 4 Ω, 5 V)  
- **Signal-to-Noise Ratio (SNR):** 95 dB (A-weighted)  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package:** 20-pin TSSOP (PowerPAD™)  

### **Descriptions:**  
- The TPA302D is a stereo Class-D audio amplifier designed for portable and battery-powered applications.  
- It features a differential input architecture to reduce noise and improve audio quality.  
- The amplifier includes built-in thermal and short-circuit protection.  
- It operates in a bridge-tied load (BTL) configuration, eliminating the need for output coupling capacitors.  

### **Features:**  
- **Low Power Consumption:** Optimized for battery life in portable devices.  
- **Pop & Click Suppression:** Minimizes audible noise during power-up/down.  
- **Thermal & Short-Circuit Protection:** Enhances reliability.  
- **Small Footprint:** 20-pin TSSOP package with PowerPAD for efficient heat dissipation.  
- **Wide Supply Voltage Range:** Supports operation from 2.5 V to 5.5 V.  
- **Differential Inputs:** Reduces common-mode noise interference.
