Description and Introduction

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

### **Key Specifications:**  
- **Output Power:** Up to 1.4W into 8Ω at 5V (THD+N = 1%)  
- **Supply Voltage Range:** 2.5V to 5.5V  
- **Efficiency:** Up to 90% (reduces power dissipation)  
- **THD+N (Total Harmonic Distortion + Noise):** 0.03% (typical at 1kHz, 1W into 8Ω)  
- **Shutdown Current:** <1µA (low power consumption in standby)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 32-pin TQFN (5mm x 5mm)  

### **Descriptions:**  
The MAX9704ETJ+ is designed for portable audio applications, providing high efficiency and low distortion. It features a differential input to reduce noise and a spread-spectrum modulation scheme to minimize EMI.  

### **Features:**  
- **Class D Operation:** High efficiency for battery-powered devices.  
- **Differential Inputs:** Rejects common-mode noise.  
- **Click-and-Pop Suppression:** Reduces audible transients during power-up/down.  
- **Short-Circuit & Thermal Protection:** Enhances reliability.  
- **Spread-Spectrum Modulation:** Lowers EMI emissions.  
- **Low Quiescent Current:** 4.5mA (typical) for extended battery life.  

This amplifier is commonly used in smartphones, portable media players, and other compact audio devices.
