Description and Introduction

3W Mono/Stereo BTL Audio Power Amplifiers with Shutdown The MAX9710ETP is a high-efficiency, mono Class D audio power amplifier manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Output Power:** Up to **3.2W** into a **4Ω** load at **5V** supply.  
- **Supply Voltage Range:** **2.7V to 5.5V** (single supply).  
- **Efficiency:** Up to **90%** (Class D operation).  
- **THD+N (Total Harmonic Distortion + Noise):** **0.03%** (typical at 1W, 4Ω load).  
- **Signal-to-Noise Ratio (SNR):** **95dB** (typical).  
- **Shutdown Current:** **0.1µA** (typical).  
- **Operating Temperature Range:** **-40°C to +85°C**.  
- **Package:** **20-pin TQFN (5x5mm)**.  

### **Descriptions:**  
The MAX9710ETP is a **mono Class D amplifier** designed for portable audio applications, offering high efficiency and low power consumption. It eliminates the need for external heat sinks due to its efficient switching operation. The device includes **click-and-pop suppression** circuitry to minimize audible noise during power-up/down.  

### **Features:**  
- **Class D Operation** for high efficiency.  
- **Low Quiescent Current** (4.5mA typical).  
- **Integrated Depop Circuitry** for noise-free power transitions.  
- **Short-Circuit and Thermal Protection**.  
- **No External Schottky Diodes Required**.  
- **Space-Saving TQFN Package**.
