Electret Microphone Amplifier - MAX9814 with Auto Gain Control

Electret Microphone Amplifier - MAX9814 with Auto Gain Control

LE 85.00


This well designed electret microphone amplifier module is a step above the rest, with built-in automatic gain control. What does this mean? The AGC in the amplifier means that near 'loud' sounds will be quieted so they don't overwhelm & 'clip' the amplifier. Also low level, quiet, far-away sounds will be amplified.

This sound detected by electret microphones module is amplified using the Maxim MAX9814, a chip that is designed for amplifying electret microphones in situations where the loudness of the audio is variable.

The module is great for when you want to record or detect audio in a setting where levels change and you don't want to have to tweak the amplifier gain all the time. You may use it in many communication and sound applications such as reactive sound projects.
