MAX4466 microphone amplifier with 20-20kHz MAX4466 microphone

The MAX4466 microphone amplifier, equipped with an electret microphone, provides excellent sound quality in the 20Hz-20kHz frequency range. It allows stepless gain adjustment from x25 to x125 via a potentiometer on the back of the unit. The amplifier is equipped with a power-coupled output, so that in conditions of complete silence and minimal amplification, the output will achieve a level of VCC/2. When connecting to alternating current (AC) powered devices, it is recommended to use a 100uF capacitor between the amplifier output and the device input to ensure optimal connection quality.
