Description and Introduction

2.6W Stereo Audio Power Amplifiers and DirectDrive® Headphone Amplifiers The **MAX9750AETI+T** is a high-efficiency, mono Class D audio power amplifier manufactured by **MAXIM Integrated** (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Output Power:**  
  - 2.8W into 4Ω at 5V (THD+N = 1%)  
  - 1.4W into 8Ω at 5V (THD+N = 1%)  
- **Supply Voltage Range:** 2.7V to 5.5V  
- **Efficiency:** Up to 90% (reduces power dissipation)  
- **THD+N (Total Harmonic Distortion + Noise):** 0.03% (typical)  
- **Shutdown Current:** <1μA  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-pin TQFN (Thin Quad Flat No-Lead)  

### **Descriptions:**  
- **Class D Amplifier:** Provides high efficiency with low heat generation.  
- **Mono Configuration:** Single-channel output.  
- **Filterless Operation:** Eliminates the need for external LC filters, reducing component count.  
- **Low EMI (Electromagnetic Interference):** Spread-spectrum modulation minimizes noise.  
- **Pop-and-Click Suppression:** Reduces audible noise during power-up/down.  

### **Features:**  
- **High Efficiency:** Up to 90%, extending battery life in portable applications.  
- **Low Quiescent Current:** 3.5mA (typical) for power-saving operation.  
- **Short-Circuit & Thermal Protection:** Safeguards the device from damage.  
- **Small Footprint:** 28-pin TQFN package (5mm x 5mm) for space-constrained designs.  
- **Wide Supply Range:** Supports 2.7V to 5.5V, making it suitable for battery-powered devices.  
- **No External Schottky Diodes Required:** Simplifies design.  

### **Applications:**  
- Portable audio devices  
- Mobile phones  
- Tablets  
- Notebook PCs  
- Gaming systems  

This amplifier is optimized for compact, battery-powered applications requiring high efficiency and minimal external components.
