Features: The MAX9814 Microphone Amplifier Module with Auto Gain Control (AGC) is a compact audio amplification module that enhances microphone signals while automatically adjusting the gain to maintain consistent output levels. This module is ideal for sound detection, voice recognition, and audio recording applications, offering easy integration and adjustable gain control. It features low-noise operation and can be powered by 3.3V or 5V, making it compatible with platforms like Arduino and Raspberry Pi. The built-in AGC ensures that audio signals, even with varying volumes, remain clear and balanced. Specifications: 3 kinds of gain settings (40dB, 50dB, 60dB) Supply Voltage: 2.7v – 5.5v @ 3mA current Output: 2Vpp on 1.25V bias Frequency Response: 20Hz – 20 KHz Low Input-Referred Noise Density of 30nV Low THD: 0.04% (typical) Automatic Gain Control (AGC) programmable action time programmable action and release time ratio Low-power shutdown mode Built-in 2 Volt low noise microphone bias Size: 26 x 14 x 11mm MAX9814 Microphone Module Pinout This module has 5 pins: VCC: Module power supply – 2.7-5.5 V GND: Ground OUT: Analog data output to the microcontroller Gain: Adjusting maximum module output* AR: Adjusting module accuracy* Applications: Speech Recognition Bluetooth Headsets Two-Way Communicators High-Quality Portable Recorders IP Phones/Telephone Conferencing Schematic Diagram: Documents MAX9814 Datasheet Categories: Audio & Sound, Sound
