Description and Introduction

1.5-W Constant Output Power Class-D Audio Amplifier With Integrated Boost Converter (TPA2014) 20-QFN -40 to 85 The TPA2014D1RGPR is a Class-D audio amplifier manufactured by Texas Instruments (TI). Below are the specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Output Power:**  
  - 1.4W into 8Ω at 5V (THD+N = 1%)  
  - 2.8W into 4Ω at 5V (THD+N = 1%)  
- **Supply Voltage Range:** 2.5V to 5.5V  
- **Efficiency:** Up to 90%  
- **Quiescent Current:** 2.4mA (typical)  
- **Shutdown Current:** <1µA  
- **Total Harmonic Distortion + Noise (THD+N):** 0.1% (typical at 1W into 8Ω)  
- **Signal-to-Noise Ratio (SNR):** 100dB (A-weighted)  
- **Gain:** Adjustable via external resistors (default 6dB)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 20-pin VQFN (RGPR)  

### **Descriptions:**  
The TPA2014D1RGPR is a mono, filter-free Class-D audio amplifier designed for portable applications. It integrates a boost converter to enhance output power while maintaining efficiency. The device features an automatic gain control (AGC) to prevent clipping and improve audio quality. It is suitable for battery-powered devices like smartphones, tablets, and portable media players.

### **Features:**  
- **Filterless Class-D Operation:** Eliminates the need for output filters.  
- **Integrated Boost Converter:** Increases output power at low supply voltages.  
- **Automatic Gain Control (AGC):** Prevents distortion by dynamically adjusting gain.  
- **Low Quiescent Current:** Extends battery life in portable applications.  
- **Thermal and Short-Circuit Protection:** Ensures device reliability.  
- **Pop-and-Click Suppression:** Minimizes noise during power-up/down.  
- **I²C Control Interface:** Allows programmable settings for gain, AGC, and shutdown.
