Description and Introduction

15W / Filterless / Spread-Spectrum Mono/Stereo Class D Amplifiers The MAX9704ETJ is a Class D audio amplifier manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated (MAXIM)  
- **Part Number:** MAX9704ETJ  
- **Type:** Class D Audio Amplifier  
- **Output Power:** Up to 20W (into 4Ω at 10% THD+N, 12V supply)  
- **Supply Voltage Range:** 4.5V to 14V  
- **Efficiency:** Up to 87%  
- **THD+N (Total Harmonic Distortion + Noise):** 0.04% (typical at 1W into 4Ω)  
- **Signal-to-Noise Ratio (SNR):** 90dB (A-weighted)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 32-pin TQFN (5mm x 5mm)  

### **Descriptions:**  
- The MAX9704ETJ is a mono, high-efficiency Class D amplifier designed for audio applications.  
- It features a fixed-gain (20dB) architecture, eliminating the need for external gain-setting resistors.  
- The device includes integrated MOSFETs, reducing external component count.  
- It supports differential or single-ended inputs and includes click-and-pop suppression circuitry.  

### **Features:**  
- **High Efficiency:** Up to 87% efficiency reduces power dissipation.  
- **Integrated MOSFETs:** Eliminates the need for external power transistors.  
- **Fixed Gain (20dB):** Simplifies design by removing external gain-setting components.  
- **Differential/Single-Ended Inputs:** Flexible input configuration options.  
- **Click-and-Pop Suppression:** Minimizes audible noise during power-up/down.  
- **Thermal and Short-Circuit Protection:** Enhances reliability.  
- **Low Quiescent Current:** 7mA (typical) for power-saving operation.  

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