Description:
The MAX9814 Microphone AGC Amplifier Module is a high-performance automatic gain control (AGC) amplifier designed for audio applications requiring low noise, low distortion, and high gain stability.
With a selectable gain of 40dB, 50dB, or 60dB, it automatically adjusts the microphone signal for optimal clarity while minimizing distortion. Its low-noise built-in microphone bias (2V) and programmable attack/release ratios make it an excellent choice for voice recording, audio surveillance, and noise-sensitive applications.
Operating on a 2.7V – 5.5V supply voltage, it offers a wide frequency response (20Hz – 20kHz), ensuring high-fidelity audio capture. The low-power shutdown mode makes it suitable for battery-powered projects.
