Description and Introduction

1.2W, Low-EMI, Filterless, Class D Audio Amplifier The **MAX9700CETB+** is a high-efficiency, mono Class D audio amplifier manufactured by **MAXIM** (now part of Analog Devices).  

### **Key Specifications:**  
- **Output Power:** Up to **20W** into a **4Ω** load at **10% THD+N** with a **12V supply**.  
- **Efficiency:** Up to **87%**, reducing power dissipation.  
- **Supply Voltage Range:** **4.5V to 14V**.  
- **THD+N (Total Harmonic Distortion + Noise):** **0.04%** (typical) at **1W** into **4Ω**.  
- **Signal-to-Noise Ratio (SNR):** **95dB** (A-weighted).  
- **Operating Temperature Range:** **-40°C to +85°C**.  
- **Package:** **TQFN-10 (3x3mm)**.

### **Features:**  
- **Class D Operation:** Provides high efficiency with minimal heat generation.  
- **Integrated MOSFETs:** Eliminates the need for external power transistors.  
- **Click-and-Pop Suppression:** Reduces audible noise during power-up/down.  
- **Short-Circuit and Thermal Protection:** Enhances reliability.  
- **Low Quiescent Current:** **4mA** (typical) for power-saving operation.  
- **Fixed Gain (6dB or 20dB):** Simplifies design by eliminating external gain-setting components.  

### **Applications:**  
- Portable audio devices  
- LCD monitors/TVs  
- Gaming consoles  
- Multimedia speakers  

This amplifier is designed for space-constrained, battery-powered applications requiring high-quality audio output with minimal power loss.
