Description and Introduction

150 mW Stereo Audio Power Amplifier The TPA112DGNR is a digital audio amplifier from Texas Instruments (TI).  

### **Specifications:**  
- **Type:** Digital Audio Amplifier  
- **Output Power:** Up to 2.8W per channel (into 4Ω at 5V)  
- **Supply Voltage Range:** 2.5V to 5.5V  
- **Efficiency:** Up to 90% (Class-D operation)  
- **THD+N:** <0.1% (1W into 4Ω)  
- **Signal-to-Noise Ratio (SNR):** >100dB  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin MSOP (DGNR)  

### **Descriptions:**  
The TPA112DGNR is a low-power, high-efficiency Class-D audio amplifier designed for portable applications. It features a differential input and can drive stereo or mono speakers with minimal external components.  

### **Features:**  
- **Class-D Operation:** High efficiency with low power dissipation  
- **Low Quiescent Current:** <4mA  
- **Short-Circuit & Thermal Protection:** Built-in safeguards  
- **Differential Inputs:** Reduces common-mode noise  
- **Pop & Click Suppression:** Minimizes audible noise during power-up/down  
- **Small Footprint:** Suitable for space-constrained designs  

For more details, refer to the official TI datasheet.
