Description and Introduction

6W, Filterless, Spread-Spectrum Mono/Stereo Class D Amplifiers The MAX9713ETJ is a stereo audio power amplifier manufactured by Maxim Integrated. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX9713ETJ  
- **Type:** Stereo Audio Power Amplifier  
- **Package:** 32-Pin TQFN (5x5mm)  
- **Supply Voltage Range:** 2.7V to 5.5V  
- **Output Power:**  
  - 1.4W per channel into 4Ω at 5V  
  - 1.1W per channel into 8Ω at 5V  
- **Efficiency:** Up to 90% (Class D operation)  
- **THD+N (Total Harmonic Distortion + Noise):** <0.1% (typical)  
- **Signal-to-Noise Ratio (SNR):** >90dB  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The MAX9713ETJ is a high-efficiency, Class D stereo audio amplifier designed for portable devices such as smartphones, tablets, and portable media players. It features a low-power shutdown mode and integrates spread-spectrum modulation to reduce EMI. The amplifier operates in a bridge-tied-load (BTL) configuration, eliminating the need for external coupling capacitors.

### **Features:**  
- **Class D Operation:** High efficiency with minimal heat dissipation.  
- **Low Quiescent Current:** Typically 4.5mA.  
- **Shutdown Mode:** Reduces power consumption to <1µA.  
- **Spread-Spectrum Modulation:** Minimizes EMI interference.  
- **Pop-and-Click Suppression:** Reduces audible noise during power-up/down.  
- **Thermal and Short-Circuit Protection:** Ensures device reliability.  
- **No External Output Filters Required:** Simplifies design.  
- **Small Footprint:** 32-pin TQFN package (5x5mm).  

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