Description and Introduction

Single/Dual, +3V/+5V Dual-Speed Comparators with Auto-Standby The MAX975ESA+ is a high-efficiency, mono Class D audio power amplifier manufactured by Maxim Integrated (now part of Analog Devices).  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Type:** Class D Audio Power Amplifier  
- **Output Power:** Up to 1.4W (into 8Ω at 5V)  
- **Supply Voltage Range:** 2.7V to 5.5V  
- **Efficiency:** Up to 90%  
- **THD+N (Total Harmonic Distortion + Noise):** 0.1% (typical)  
- **Shutdown Current:** <1μA  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC  

### **Descriptions:**  
The MAX975ESA+ is designed for portable audio applications, providing high-efficiency amplification with low power consumption. It eliminates the need for external inductors, reducing board space and cost.  

### **Features:**  
- **Filterless Operation:** No external LC filter required.  
- **Low Quiescent Current:** 2.5mA (typical).  
- **Thermal and Short-Circuit Protection:** Built-in safeguards.  
- **Pop-and-Click Suppression:** Minimizes noise during power-up/down.  
- **Single-Ended Input:** Simplifies design integration.

Application Scenarios & Design Considerations

Single/Dual, +3V/+5V Dual-Speed Comparators with Auto-Standby

Alternative Part Number

  • LTC1540CS8#PBF --: Pin-compatible single comparator in SO-8 with similar low-power, low-voltage operation; direct functional substitute from a different series.
  • TLV3011IDBVR --: Low-power comparator with open-drain output and similar supply range, suitable replacement in SOT-23 or SO-8 designs.
  • LM393DR --: Widely available dual comparator; one channel can replace the single comparator with minor layout changes, low cost and broad availability.
  • LT1720CS8 --: Single-supply comparator with similar speed and response time, available in SO-8 package, suitable functional replacement.
  • TLV3201IDR --: Low-power high-speed comparator with comparable propagation delay, offered in SOIC package for drop-in style use.
