### **Descriptions:**
The TPA122DR is a low-voltage, stereo audio power amplifier designed for portable audio applications. It operates efficiently within a 2.5V to 5.5V supply range, making it suitable for battery-powered devices. The amplifier features a fixed gain of 6dB and provides high-quality audio output with low distortion and noise.  

### **Features:**
- **Low Voltage Operation:** Supports 2.5V to 5.5V supply range.  
- **Low Power Consumption:** 3.5mA quiescent current for extended battery life.  
- **Ultra-Low Shutdown Current:** 0.1μA in shutdown mode.  
- **Thermal & Short-Circuit Protection:** Built-in safeguards for reliability.  
- **Fixed Gain:** Eliminates the need for external gain-setting components.  
- **Improved PSRR (Power Supply Rejection Ratio):** Reduces noise from power supply variations.  
- **Small Footprint:** SOIC-8 package for space-constrained designs.  

This information is based solely on the manufacturer's datasheet and technical documentation.
