Description and Introduction

Ultra-Low-Power / Open-Drain / Single/Dual-Supply Comparators The MAX981ESA is a microphone amplifier manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Supply Voltage Range:** 2.7V to 5.5V  
- **Quiescent Current:** 600µA (typical)  
- **Gain:** Adjustable (20dB, 40dB, 50dB, 60dB) via external resistor  
- **Bandwidth:** 20kHz (typical)  
- **Input-Referred Noise:** 30nV/√Hz (typical)  
- **Total Harmonic Distortion (THD):** 0.04% (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC  

### **Descriptions:**  
The MAX981ESA is a low-noise, high-performance microphone amplifier designed for audio applications. It features automatic gain control (AGC) to prevent clipping and maintain consistent output levels. The device is optimized for use with electret microphones and provides adjustable gain settings for flexibility in different applications.  

### **Features:**  
- Low-noise preamplifier for electret microphones  
- Adjustable gain via external resistor  
- Built-in AGC for dynamic signal control  
- Low quiescent current for power efficiency  
- Wide supply voltage range (2.7V to 5.5V)  
- Small 8-pin SOIC package for space-constrained designs  
- Suitable for battery-powered applications  

This information is based solely on the manufacturer's datasheet and technical documentation.
