The MAX9814 High-Performance Electret Microphone Amplifier Module by FamePhase Electronics Accessories is an advanced audio-sensing solution built for precision acoustic monitoring and voice processing applications. Equipped with integrated Automatic Gain Control (AGC), it dynamically optimizes signal levels by boosting faint whispers while compressing loud audio spikes to prevent signal clipping. Powered smoothly between 2.4V and 5.5V DC, it provides a centered 1.25V analog output ideal for microcontrollers like Arduino, ESP32, and Raspberry Pi. Featuring configurable maximum gain (40/50/60dB) and adjustable attack-to-release ratios, this module is the perfect choice for smart voice control interfaces, sound-level meters, and DIY audio recording setups.
