Description and Introduction

Micropower / Low-Voltage / SOT23 / Rail-to-Rail I/O Comparators The MAX985ESA is a high-performance, low-power audio amplifier manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Type:** Audio Power Amplifier  
- **Package:** 8-SOIC  
- **Operating Voltage Range:** 2.7V to 5.5V  
- **Output Power:** Up to 1W (into 8Ω at 5V)  
- **Total Harmonic Distortion + Noise (THD+N):** 0.015% (typical)  
- **Signal-to-Noise Ratio (SNR):** 95dB (typical)  
- **Quiescent Current:** 4mA (typical)  
- **Shutdown Current:** 0.1μA (typical)  
- **Gain:** Fixed at 6dB  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
The MAX985ESA is a mono Class AB audio amplifier designed for portable and battery-powered applications. It provides high-quality audio amplification with low power consumption, making it suitable for devices like smartphones, portable media players, and handheld gaming systems. The amplifier features a shutdown mode to minimize power consumption when not in use.

### **Features:**
- Low-voltage operation (2.7V to 5.5V)  
- High output power (1W into 8Ω at 5V)  
- Low THD+N for high audio fidelity  
- Ultra-low shutdown current (0.1μA)  
- No external output coupling capacitors required  
- Thermal and short-circuit protection  
- Space-saving 8-pin SOIC package

Application Scenarios & Design Considerations

Micropower / Low-Voltage / SOT23 / Rail-to-Rail I/O Comparators

Alternative Part Number

  • LMV7219M5 --: Low-power comparator with similar supply range and push-pull output, pin-compatible in many comparator applications.
  • TLV3201AIDBVR --: Rail-to-rail comparator with comparable propagation delay and supply voltage, suitable drop-in for low-voltage comparator designs.
  • ADCMP600BRJZ --: High-speed comparator with similar input/output characteristics and wide supply range, usable as a functional substitute.
