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 manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Output Power:** Up to 2.8W (into 4Ω at 5V)  
- **Supply Voltage Range:** 2.7V to 5.5V  
- **Efficiency:** Up to 90% (Class D operation)  
- **THD+N (Total Harmonic Distortion + Noise):** 0.03% (typical at 1W into 4Ω)  
- **Shutdown Current:** <1µA  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 14-pin SOIC (ESD)  

### **Descriptions:**  
- The MAX970ESD+ is a mono, filterless Class D amplifier designed for portable and battery-powered audio applications.  
- It eliminates the need for bulky external LC filters, reducing component count and PCB space.  
- Features a differential input for improved noise rejection and a low-power shutdown mode.  

### **Features:**  
- **Filterless Class D Operation:** Reduces external component requirements.  
- **Low Quiescent Current:** 3.5mA (typical) for extended battery life.  
- **Click-and-Pop Suppression:** Minimizes audible transients during power-up/down.  
- **Thermal and Short-Circuit Protection:** Ensures reliability in harsh conditions.  
- **Differential Input:** Reduces common-mode noise.
