Description and Introduction

Single/Dual/Quad / Micropower / Ultra-Low-Voltage / Rail-to-Rail I/O Comparators The MAX970ESD is a high-efficiency, mono Class D audio power amplifier from Maxim Integrated. Here are its key specifications, descriptions, and features:

### **Manufacturer:**  
Maxim Integrated (now part of Analog Devices)  

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

### **Descriptions:**  
- Mono Class D amplifier optimized for high efficiency and low heat dissipation.  
- Uses a fixed-frequency PWM modulation scheme for reduced EMI.  
- Requires minimal external components for operation.  
- Suitable for battery-powered and space-constrained applications.  

### **Features:**  
- **Spread-Spectrum Modulation:** Reduces EMI emissions.  
- **Short-Circuit & Thermal Protection:** Built-in safeguards.  
- **Low Quiescent Current:** 4mA (typical).  
- **Pop-and-Click Suppression:** Minimizes audible noise during power-up/down.  
- **Small Footprint:** Available in an 14-pin SOIC package.  

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

(Note: Always refer to the official datasheet for detailed specifications.)
