Description and Introduction

10W Stereo/15W Mono, Filterless, Spread-Spectrum, Class D Amplifiers The MAX9703ETJ+ is a mono Class D audio power amplifier manufactured by Maxim Integrated.  

### **Specifications:**  
- **Output Power:** Up to 12W (into 4Ω at 10% THD+N, 12V supply)  
- **Supply Voltage Range:** 4.5V to 14V  
- **Efficiency:** Up to 87%  
- **THD+N (Total Harmonic Distortion + Noise):** 0.04% (1W into 4Ω)  
- **Signal-to-Noise Ratio (SNR):** 95dB (A-weighted)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 32-pin TQFN (5mm x 5mm)  

### **Descriptions:**  
The MAX9703ETJ+ is a high-efficiency, mono Class D amplifier designed for audio applications. It integrates a high-performance PWM modulator and MOSFET output stage, reducing external component count. It features click-and-pop suppression and thermal overload protection.  

### **Features:**  
- **Spread-Spectrum Modulation:** Reduces EMI emissions  
- **Short-Circuit and Thermal Protection:** Enhances reliability  
- **Low Quiescent Current:** 7.5mA (typical)  
- **Differential Inputs:** Improves noise rejection  
- **No External LC Filter Required:** Simplifies design  
- **Shutdown Mode:** Reduces power consumption  

This amplifier is commonly used in portable speakers, LCD TVs, and other audio systems requiring efficient power amplification.
