- **Part Number:** MAX9702ETI+T  
- **Type:** Class D Audio Amplifier  
- **Output Power:** Up to 20W (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% (typical at 1W, 4Ω)  
- **Signal-to-Noise Ratio (SNR):** 90dB (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-pin TQFN (Thin Quad Flat No-Lead)  

### **Descriptions:**
The MAX9702ETI+T is a high-efficiency, mono Class D audio amplifier designed for portable and space-constrained applications. It integrates a high-performance PWM modulator and MOSFET output stage, delivering high-quality audio with minimal heat dissipation.  

### **Features:**
- **High Efficiency:** Up to 87% efficiency reduces power consumption and heat generation.  
- **Low EMI (Electromagnetic Interference):** Spread-spectrum modulation minimizes EMI.  
- **Short-Circuit & Thermal Protection:** Built-in safeguards protect the device.  
- **Low Quiescent Current:** 4mA (typical) for power-saving operation.  
- **Single-Supply Operation:** Works from 4.5V to 14V, suitable for battery-powered applications.  
- **Pop-and-Click Suppression:** Reduces audible noise during power-up/down.  
- **Small Footprint:** 28-pin TQFN package saves board space.
