Description and Introduction

1.25-W Mono Fully-Differential Audio Power Amplifier The TPA6203A1 is a mono, bridged-tied load (BTL) audio power amplifier manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **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:** 0.1 μA (typical)  
- **Total Harmonic Distortion + Noise (THD+N):** 0.2% (typical at 1 kHz, 1 W into 8 Ω)  
- **Signal-to-Noise Ratio (SNR):** 95 dB (typical)  
- **Gain:** Fixed at 6 dB  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package:** 8-pin SOIC (D)  

### **Descriptions:**  
- The TPA6203A1 is a low-power, high-efficiency Class-AB audio amplifier designed for portable applications.  
- It features a differential input to reduce noise and improve common-mode rejection.  
- The device includes thermal and short-circuit protection.  
- It is optimized for driving small speakers in battery-powered devices such as mobile phones, PDAs, and portable media players.  

### **Features:**  
- **Low Quiescent Current:** Reduces power consumption in battery-operated devices.  
- **Shutdown Mode:** Minimizes power draw when not in use.  
- **Thermal and Short-Circuit Protection:** Enhances reliability.  
- **No Output Coupling Capacitors Required:** Saves board space and cost.  
- **Improved PSRR (Power Supply Rejection Ratio):** Reduces noise from the power supply.  
- **Small Footprint:** 8-pin SOIC package enables compact designs.  

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