Description and Introduction

Ultra-Low-Power, Open-Drain, Single/Dual-Supply Comparators The MAX982CSA+ is a microphone amplifier with automatic gain control (AGC) manufactured by Maxim Integrated (now part of Analog Devices).  

### **Key Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Type:** Microphone Amplifier with AGC  
- **Package:** 8-SOIC  
- **Operating Voltage Range:** 2.7V to 5.5V  
- **Quiescent Current:** 1.1mA (typical)  
- **Gain Range:** Adjustable (with AGC)  
- **AGC Range:** Up to 30dB  
- **Signal-to-Noise Ratio (SNR):** >90dB  
- **THD+N (Total Harmonic Distortion + Noise):** <0.1%  
- **Bandwidth:** 20Hz to 20kHz  
- **Input Referred Noise:** 4.5µV (typical)  

### **Description:**  
The MAX982CSA+ is a low-power, high-performance microphone amplifier with built-in automatic gain control (AGC). It is designed for applications requiring consistent audio levels, such as voice recorders, communication devices, and audio processing systems. The AGC feature ensures optimal signal levels even with varying input volumes.  

### **Features:**  
- Low quiescent current (1.1mA typical)  
- Wide supply voltage range (2.7V to 5.5V)  
- Integrated AGC with adjustable threshold and attack/release times  
- Low noise and low distortion  
- Single-supply operation  
- Small footprint (8-SOIC package)  
- Suitable for electret and MEMS microphones  

This device is ideal for battery-powered and portable audio applications where maintaining consistent audio levels is critical.
