Description and Introduction

1.4-W Mono Class-D Audio Amplifier (TPA2005) 8-MSOP-PowerPAD -40 to 85 The TPA2005D1DGNRG4 is a Class-D audio amplifier manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Texas Instruments (TI)  
- **Part Number:** TPA2005D1DGNRG4  
- **Type:** Class-D Mono Audio Amplifier  
- **Output Power:** 1.1W into 8Ω at 5V  
- **Supply Voltage Range:** 2.5V to 5.5V  
- **Efficiency:** Up to 90%  
- **THD+N (Total Harmonic Distortion + Noise):** 0.3% (typical)  
- **Shutdown Current:** <1µA  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package:** MSOP-8 (DGNR)  

### **Descriptions:**
- The TPA2005D1DGNRG4 is a mono, filter-free Class-D audio amplifier designed for low-power applications.  
- It is optimized for driving small speakers in portable devices such as smartphones, tablets, and portable media players.  
- The amplifier operates efficiently with minimal external components, making it suitable for space-constrained designs.  

### **Features:**  
- **Filterless Operation:** Eliminates the need for external LC filters.  
- **Low Quiescent Current:** 2.4mA (typical) for extended battery life.  
- **Click-and-Pop Suppression:** Reduces audible noise during power-up/down.  
- **Short-Circuit and Thermal Protection:** Enhances reliability.  
- **Small Footprint:** MSOP-8 package saves PCB space.  
- **Wide Supply Range:** Supports operation from 2.5V to 5.5V.  

This information is based on TI's official datasheet for the TPA2005D1DGNRG4.
