Description and Introduction

Low-Cost, Mono, 1.4W BTL Audio Power Amplifiers The MAX9717BEUA is a high-efficiency, mono Class D audio amplifier manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Output Power:** Up to **2.8W** 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):** **0.04%** (typical at 1W into 4Ω).  
- **SNR (Signal-to-Noise Ratio):** **95dB** (A-weighted).  
- **Shutdown Current:** **0.1µA** (typical).  
- **Operating Temperature Range:** **-40°C to +85°C**.  
- **Package:** **8-pin µMAX® (UMAX)**.  

### **Descriptions:**  
The MAX9717BEUA is a **mono, filterless, Class D audio amplifier** designed for portable and battery-powered applications. It eliminates the need for bulky external LC filters, reducing PCB space and cost. The device features **low EMI (Electromagnetic Interference)** and **high efficiency**, making it ideal for smartphones, tablets, portable media players, and other compact audio systems.  

### **Features:**  
- **Filterless Class D Operation** – No external LC filter required.  
- **Low Quiescent Current** – **3.5mA** (typical).  
- **Click-and-Pop Suppression** – Minimizes audible noise during power-up/down.  
- **Thermal and Short-Circuit Protection** – Enhances reliability.  
- **Low-Power Shutdown Mode** – Reduces power consumption when inactive.  
- **Space-Saving Package** – 8-pin µMAX (3mm x 3mm).  

This amplifier is optimized for **high-quality audio output** with minimal power consumption, making it suitable for portable and space-constrained designs.
