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

### **Specifications:**  
- **Output Power:** Up to **20W** into a **4Ω** load with **10% THD+N** (when powered by **12V**).  
- **Supply Voltage Range:** **4.5V to 14V** (single supply).  
- **Efficiency:** Up to **87%**, reducing power dissipation.  
- **THD+N (Total Harmonic Distortion + Noise):** Typically **0.04%** at **1W** into **4Ω**.  
- **Signal-to-Noise Ratio (SNR):** **90dB** (A-weighted).  
- **Switching Frequency:** **1.2MHz** (fixed).  
- **Shutdown Current:** **<1µA** (low-power mode).  
- **Operating Temperature Range:** **-40°C to +85°C**.  
- **Package:** **16-pin QSOP (EE)**.  

### **Descriptions:**  
- The MAX970EEE is a **monolithic Class D amplifier** designed for high-efficiency audio applications.  
- It integrates a **PWM modulator**, **MOSFET gate drivers**, and **feedback loop** for improved performance.  
- Suitable for **portable speakers, LCD TVs, gaming systems, and automotive audio**.  

### **Features:**  
- **Filterless Operation:** Eliminates the need for external LC filters.  
- **Click-and-Pop Suppression:** Reduces audible noise during power-up/down.  
- **Thermal and Short-Circuit Protection:** Enhances reliability.  
- **Low Quiescent Current:** **4.5mA** (typical).  
- **Single-Supply Operation:** Simplifies power requirements.  
- **Differential Inputs:** Reduces common-mode noise.

Application Scenarios & Design Considerations

Single/Dual/Quad / Micropower / Ultra-Low-Voltage / Rail-to-Rail I/O Comparators

Alternative Part Number

  • LTC1540CS8 --: Pin-compatible comparator with similar supply range and open-drain output, widely used as a MAX970 drop-in in 8-pin SO packages.
  • TLV3011IDBVR --: Low-power comparator with integrated reference, comparable response time and supply voltage, suitable functional replacement in SOT-23 or SOIC designs.
  • LM393DR --: Industry-standard dual comparator with similar electrical characteristics; requires minor pinout adaptation but is a low-cost, readily available alternative.
  • LTC1540CMS8 --: Pin-compatible comparator with similar supply voltage range and open-drain output, widely available and often used as a MAX970 substitute.
  • TLV3011ACDBVR --: Low-power comparator with integrated reference, comparable function and small package, suitable for battery-powered designs replacing the MAX970.
