Description and Introduction

Mono Class-AB Audio Amplifier with Active HIgh Shutdown The TPA721DR is a 1.2W audio power amplifier manufactured by Texas Instruments (TI). Here are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Output Power:** 1.2W into 8Ω at 5V  
- **Supply Voltage Range:** 2.5V to 5.5V  
- **Quiescent Current:** 2.3mA (typical)  
- **Shutdown Current:** 0.1μA (typical)  
- **THD+N (Total Harmonic Distortion + Noise):** 0.2% (typical) at 1kHz, 1W into 8Ω  
- **Gain:** Fixed at 6dB  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-8 (DR)  

### **Descriptions:**  
- The TPA721DR is a mono, bridge-tied load (BTL) audio amplifier designed for low-voltage applications.  
- It is optimized for portable devices such as mobile phones, PDAs, and portable media players.
