Description and Introduction

10W Stereo/15W Mono, Filterless, Spread-Spectrum, Class D Amplifiers The MAX9704ETJ+T is a high-efficiency, mono Class D audio power amplifier manufactured by Maxim Integrated.  

### **Specifications:**  
- **Output Power:** Up to 1.4W into 8Ω at 5V  
- **Efficiency:** Up to 90%  
- **Supply Voltage Range:** 2.5V to 5.5V  
- **THD+N (Total Harmonic Distortion + Noise):** 0.04% (typical)  
- **SNR (Signal-to-Noise Ratio):** 95dB (typical)  
- **Shutdown Current:** <1µA  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 32-Pin TQFN-EP (5mm x 5mm)  

### **Descriptions:**  
The MAX9704ETJ+T is a low-power, high-performance Class D amplifier designed for portable audio applications. It features a filterless modulation scheme, eliminating the need for external output filters. The device includes click-and-pop suppression circuitry to minimize audible noise during power-up/down.  

### **Features:**  
- Filterless Class D operation  
- Low quiescent current (4.5mA typical)  
- Thermal and short-circuit protection  
- Click-and-pop suppression  
- Low EMI (Electromagnetic Interference)  
- Differential inputs for improved noise rejection  
- Available in a compact 32-pin TQFN-EP package  

This amplifier is suitable for battery-powered devices such as smartphones, tablets, and portable media players.

Application Scenarios & Design Considerations
