- **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 TPA3100D2RGZRG4 is a high-efficiency, Class-D stereo audio amplifier designed for consumer audio applications.  
- It integrates a high-performance PWM modulator and MOSFET power stage, reducing external component count.  
- Features built-in protection circuits, including overcurrent, overtemperature, and undervoltage lockout.  

### **Features:**  
- **High Efficiency:** Class-D architecture minimizes power dissipation.  
- **Low EMI:** Spread-spectrum modulation reduces electromagnetic interference.  
- **Flexible Input:** Accepts differential or single-ended audio inputs.  
- **Pop & Click Suppression:** Minimizes audible noise during power-up/down.  
- **Short-Circuit & Thermal Protection:** Enhances system reliability.  
- **Small Footprint:** 48-pin VQFN package saves board space.  

This amplifier is commonly used in TVs, soundbars, portable speakers, and other audio applications requiring high efficiency and compact design.
