MAX9814 Microphone Amp. Module
MAX9814 Microphone Amp. Module
The MAX9814 Microphone Amplifier Module is a high-quality electret microphone breakout featuring Automatic Gain Control (AGC) for clear and consistent audio capture across varying sound levels. It is designed to amplify low-level microphone signals while automatically adjusting gain to prevent clipping and distortion. This makes it ideal for voice detection, audio recording, and sound-reactive projects using Arduino, ESP32, Raspberry Pi, and other microcontrollers.
Technical Specifications:
- Audio amplifier IC: MAX9814
- Microphone type: Electret condenser microphone
- Operating voltage: 2.7 V – 5.5 V

- Gain pin floating: 60 dB
- Gain pin to GND: 50 dB
- Gain pin to VDD: 40 dB
- AGC: Built-in, selectable attack/release via AR pin
- DC offset: ~1.25 V
- Frequency response: Optimized for voice/audio
- PCB material: FR-4
- Mounting: 4 corner mounting holes
Features:
- Built-in Automatic Gain Control (AGC) for stable audio levels
- Clear voice pickup with low noise
- Selectable gain options (40 dB / 50 dB / 60 dB)
- Wide operating voltage range (3.3 V & 5 V compatible)
- Compact breakout board for easy prototyping
- Simple analog output compatible with ADC pins
- Ideal for real-time sound detection and recording
Applications:
- Voice recognition systems
- Sound level detection
- Audio recording projects
