Description and Introduction

Single/Dual/Quad, Micropower, Ultra-Low-Voltage, Rail-to-Rail I/O Comparators The MAX970EEE+ is a high-efficiency, mono Class D audio power amplifier from Maxim Integrated (now part of Analog Devices).  

### **Manufacturer:**  
- **MAXIM Integrated (Analog Devices)**  

### **Specifications:**  
- **Output Power:** Up to 20W (into 4Ω at 10% THD+N, 12V supply)  
- **Efficiency:** Up to 90%  
- **Supply Voltage Range:** 4.5V to 14V  
- **THD+N (Total Harmonic Distortion + Noise):** 0.04% (typical at 1W, 8Ω)  
- **Signal-to-Noise Ratio (SNR):** >100dB (A-weighted)  
- **Shutdown Current:** <1µA  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin QSOP  

### **Descriptions:**  
- Designed for high-efficiency audio amplification in portable and battery-powered applications.  
- Features a spread-spectrum modulation scheme to reduce EMI.  
- Includes click-and-pop suppression for noise-free operation.  
- Requires minimal external components.  

### **Features:**  
- **Class D Operation:** High efficiency with low power dissipation.  
- **Filterless Operation:** Eliminates the need for an output filter.  
- **Short-Circuit & Thermal Protection:** Built-in safeguards.  
- **Low Quiescent Current:** 4mA (typical).  
- **Single-Supply Operation:** Simplifies power requirements.  

This amplifier is commonly used in portable speakers, LCD TVs, and automotive audio systems.
