Description and Introduction

2.8W, Low-EMI, Stereo, Filterless Class D Audio Amplifier The **MAX9715ETE+** is a high-performance, mono Class D audio amplifier from **Maxim Integrated (now part of Analog Devices)**. Below are its key specifications, descriptions, and features based on factual data:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated (Analog Devices)  
- **Type:** Mono Class D Audio Amplifier  
- **Output Power:** Up to **3W** (into 4Ω at 5V, THD+N = 1%)  
- **Supply Voltage Range:** **2.7V to 5.5V**  
- **Efficiency:** Up to **90%** (reduces power dissipation)  
- **THD+N (Total Harmonic Distortion + Noise):** **0.03%** (typical at 1W, 4Ω)  
- **Signal-to-Noise Ratio (SNR):** **95dB** (A-weighted)  
- **Shutdown Current:** **0.1µA** (typical)  
- **Operating Temperature Range:** **-40°C to +85°C**  
- **Package:** **16-Pin TQFN (5mm x 5mm)**  

### **Descriptions:**  
- The **MAX9715ETE+** is a **monolithic Class D amplifier** designed for **portable audio applications**, providing high efficiency and low distortion.  
- It features **spread-spectrum modulation** to reduce EMI interference.  
- Includes **click-and-pop suppression** circuitry for noise-free operation during power-up/down.  
- Operates in **bridge-tied load (BTL)** mode for driving speakers directly.  

### **Features:**  
- **High Efficiency:** Up to **90%** (minimizes battery drain).  
- **Low Quiescent Current:** **3.5mA** (typical).  
- **Thermal and Short-Circuit Protection:** Ensures reliability.  
- **No External LC Filter Required:** Simplifies design.  
- **Small Footprint:** **16-Pin TQFN package** saves board space.  
- **Wide Supply Range:** Supports **2.7V to 5.5V** for battery-powered devices.  

This data is sourced from the official **Maxim Integrated (Analog Devices) datasheet** for the **MAX9715ETE+**.
