Description and Introduction

Low-Cost, Mono/Stereo, 1.4W Differential Audio Power Amplifiers The **MAX9718DETB+T** is a high-performance, stereo Class D audio amplifier manufactured by **Maxim Integrated** (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Type:** Stereo Class D Audio Amplifier  
- **Output Power:**  
  - **2.8W per channel** (into 4Ω at 5V, THD+N = 1%)  
  - **1.4W per channel** (into 8Ω at 5V, THD+N = 1%)  
- **Supply Voltage Range:** **2.7V to 5.5V**  
- **Efficiency:** Up to **90%**  
- **THD+N (Total Harmonic Distortion + Noise):** **<0.1%** (typical)  
- **Signal-to-Noise Ratio (SNR):** **>90dB**  
- **Shutdown Current:** **<1µA**  
- **Operating Temperature Range:** **-40°C to +85°C**  
- **Package:** **14-Pin TDFN (3mm x 3mm)**  

### **Descriptions:**
- The MAX9718DETB+T is a **low-power, high-efficiency** Class D amplifier designed for portable audio applications.  
- It features **filterless modulation**, eliminating the need for external LC filters.  
- The device includes **click-and-pop suppression** circuitry to minimize audible noise during power-up/down.  
- It supports **single-ended or differential inputs** and has a **low-power shutdown mode**.  

### **Features:**
- **Filterless Class D Operation** – Reduces external component count.  
- **Low Quiescent Current** – **3.5mA** (typical) for extended battery life.  
- **Short-Circuit and Thermal Protection** – Enhances reliability.  
- **Wide Supply Voltage Range** (2.7V to 5.5V) – Suitable for battery-powered devices.  
- **Small Footprint** – 14-pin TDFN package (3mm x 3mm) for space-constrained designs.  
- **Improved EMI Performance** – Minimizes interference in sensitive applications.  

This information is strictly based on the manufacturer's datasheet and technical documentation.
