Description and Introduction

Mono, Differential Input, Class-AB Audio Amplifier with Active High Shutdown The TPA731DGN is a 1.5-W mono audio power amplifier manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Output Power:** 1.5 W into 8 Ω at 5 V  
- **Supply Voltage Range:** 2.5 V to 5.5 V  
- **Quiescent Current:** 2.3 mA (typical)  
- **Total Harmonic Distortion + Noise (THD+N):** 0.3% (typical at 1 kHz, 1 W into 8 Ω)  
- **Shutdown Current:** 0.01 µA (typical)  
- **Gain:** Fixed at 6 dB (internally set)  
- **Package:** MSOP-8 (DGN)  

### **Descriptions:**  
The TPA731DGN is a low-voltage, mono audio amplifier designed for portable applications. It features an integrated depop circuit to minimize audible noise during power-up and shutdown. The device operates efficiently with a wide supply voltage range, making it suitable for battery-powered systems.  

### **Features:**  
- **Low Quiescent Current:** Extends battery life in portable devices.  
- **Thermal and Short-Circuit Protection:** Enhances reliability.  
- **No External Output Coupling Capacitors Required:** Reduces component count.  
- **Click-and-Pop Suppression:** Minimizes audible transients.  
- **Unity-Gain Stable:** Can be used in various configurations.  
- **Small Footprint:** MSOP-8 package saves board space.
