Description and Introduction

20-W Stereo Class-D Audio Power Amplifier (TPA3100) 48-VQFN -40 to 85 The TPA3100D2RGZTG4 is a Class-D audio amplifier manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Part Number:** TPA3100D2RGZTG4  
- **Type:** Class-D Stereo Audio Amplifier  
- **Output Power:**  
  - 20W per channel into 4Ω at 10% THD+N (VDD = 21V)  
  - 15W per channel into 8Ω at 10% THD+N (VDD = 21V)  
- **Supply Voltage Range (VDD):** 8V to 26V  
- **Efficiency:** Up to 90%  
- **THD+N (Total Harmonic Distortion + Noise):** 0.1% (typical)  
- **Signal-to-Noise Ratio (SNR):** 95dB (A-weighted)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 48-Pin VQFN (RGZ)  

### **Descriptions:**  
- The TPA3100D2RGZTG4 is a high-efficiency Class-D stereo audio amplifier designed for consumer audio applications.  
- It features a fully differential design with integrated feedback for improved noise immunity.  
- Includes built-in protection features such as overcurrent, undervoltage, and thermal shutdown.  

### **Features:**  
- **High Efficiency:** Class-D architecture reduces power dissipation.  
- **Low EMI:** Spread-spectrum modulation minimizes electromagnetic interference.  
- **Flexible Inputs:** Supports single-ended and differential inputs.  
- **Pop & Click Suppression:** Reduces audible noise during power-up/down.  
- **Short-Circuit Protection:** Integrated safeguards for output faults.  
- **Standby Mode:** Low-power consumption when not in use.  

This information is sourced from TI’s official datasheet for the TPA3100D2RGZTG4.
