### **Descriptions:**
The TPA3100D2RGZT is a high-efficiency, Class-D stereo audio amplifier designed for consumer audio applications. It integrates a PWM modulator and MOSFET output stage, delivering high-quality audio with minimal heat dissipation. The device supports single-ended or differential inputs and includes built-in protection features such as overcurrent, overtemperature, and undervoltage lockout (UVLO).

### **Features:**
- **High Efficiency:** Up to 90% reduces power dissipation.  
- **Flexible Input Options:** Supports single-ended or differential inputs.  
- **Integrated Feedback:** Eliminates the need for external feedback components.  
- **Short-Circuit Protection:** Includes overcurrent and thermal shutdown.  
- **Pop & Click Suppression:** Minimizes audible noise during power-up/down.  
- **Standby & Mute Modes:** Low-power consumption when inactive.  
- **Wide Supply Range:** Operates from 8V to 26V, suitable for various applications.
