1.25-W Mono, Fully Differential, Class-AB Audio Amplifier 8-SON -40 to 85 The TPA6203A1DRBRG4 is a mono, 1.1-W audio power amplifier manufactured by Texas Instruments. Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Power:** 1.1 W into 8 Ω at 5 V (THD+N = 10%)  
- **Supply Voltage Range:** 2.5 V to 5.5 V  
- **Quiescent Current:** 2.5 mA (typical)  
- **Shutdown Current:** 0.01 µA (typical)  
- **Total Harmonic Distortion + Noise (THD+N):** 0.2% (typical at 1 kHz, 1 W into 8 Ω)  
- **Gain:** Fixed at 6 dB (V/V)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SON-8 (DRB)  

### **Descriptions:**
- The TPA6203A1DRBRG4 is a Class-AB audio amplifier designed for portable applications.  
- It features an integrated depop circuit to reduce audible pops and clicks during power-up and shutdown.  
- The device is optimized for low-voltage operation, making it suitable for battery-powered systems.  

### **Features:**
- **Low Quiescent Current:** Enhances battery life in portable devices.  
- **Thermal and Short-Circuit Protection:** Ensures device reliability.  
- **Space-Saving Package:** SON-8 (2 mm × 2 mm) for compact PCB designs.  
- **No External Bootstrap Capacitors Needed:** Simplifies design and reduces BOM cost.  
- **Improved PSRR (Power Supply Rejection Ratio):** Reduces noise from the power supply.  

This amplifier is commonly used in mobile phones, portable audio devices, and other low-power audio applications.
