HALJIA 3PCS MAX4466 Electret Microphone Amplifier MAX4466 Sound Sensor Module Adjustable Gain Module Breakout Sensor Board Compatible with Arduino

Describtion: The MAX4466 is a micropower operational amplifier optimized for use as a microphone preamplifier. They provide an ideal combination of optimized gain bandwidth products and supply current, and low voltage operation in ultra-small packages. The MAX4466 has gain stability, requiring only 24μA of supply current to provide a gain bandwidth of 200kHz. After decompression, a minimum stable gain of +5V/V can be achieved, and a gain bandwidth product of 600kHz is provided. On the back, we include a small trimmer pot to adjust the gain. You can set the gain from 25x to 125x. That's down to be about 200mVpp (for normal speaking volume about 6"" away).In addition, these amplifiers have rail-to-rail output, high AVOL, and excellent power supply rejection and common-mode rejection ratio, suitable for operation in noisy environments.Widely used in cellular phones, digital repeaters, earphones, hearing aids, microphone preamplifiers, portable computers, voice recognition systems.This br
