Description and Introduction

6W, Filterless, Spread-Spectrum Mono/Stereo Class D Amplifiers The MAX9714ETJ+T is a high-efficiency, mono Class D audio power amplifier from Maxim Integrated.  

### **Key Specifications:**  
- **Output Power:** Up to 2.8W into 4Ω (at 5V supply)  
- **Supply Voltage Range:** 2.7V to 5.5V  
- **Efficiency:** Up to 90% (reduces power dissipation)  
- **THD+N (Total Harmonic Distortion + Noise):** 0.03% (1W into 4Ω)  
- **Shutdown Current:** <1µA (low-power mode)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 32-pin TQFN (5mm x 5mm)  

### **Descriptions & Features:**  
- **Class D Amplifier:** Provides high efficiency with low heat dissipation.  
- **Filterless Operation:** Eliminates the need for external LC filters.  
- **Pop-and-Click Suppression:** Minimizes audible noise during power-up/down.  
- **Low Quiescent Current:** 3.5mA (typical) for extended battery life.  
- **Thermal and Short-Circuit Protection:** Enhances reliability.  
- **Single-Ended Input:** Simplifies design for portable applications.  
- **Fixed Gain (6dB):** Reduces external component count.  

This amplifier is commonly used in portable devices, smartphones, tablets, and other battery-powered audio applications.
