Description and Introduction

Low-Cost, Mono/Stereo, 1.4W Differential Audio Power Amplifiers The MAX9718EEBL+TG45 is a high-efficiency, mono Class D audio power amplifier manufactured by Maxim Integrated.  

### **Specifications:**  
- **Output Power:** Up to 3.2W into 4Ω at 5V supply  
- **Supply Voltage Range:** 2.5V to 5.5V  
- **Efficiency:** Up to 90%  
- **THD+N (Total Harmonic Distortion + Noise):** 0.03% (typical)  
- **Shutdown Current:** <1µA  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 9-Bump WLP (Wafer-Level Package)  

### **Descriptions:**  
The MAX9718 is a mono, filterless Class D amplifier designed for portable audio applications. It features a low-noise, high-efficiency architecture with a fixed gain of 6dB. The device operates without requiring external output filters, simplifying design while reducing component count.  

### **Features:**  
- **Filterless Class D Operation** – Eliminates need for bulky output filters  
- **Low Quiescent Current** – 3.5mA (typical)  
- **Pop-and-Click Suppression** – Minimizes audible noise during power-up/down  
- **Short-Circuit and Thermal Protection** – Enhances reliability  
- **Space-Saving WLP Package** – Ideal for compact designs  

This amplifier is commonly used in smartphones, tablets, portable media players, and other battery-powered audio devices.
