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

The MAX4466 is a micropower operational amplifier optimized for use as a microphone preamplifier. 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. 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 breakout is best used for projects such as voice changers, audio recordingmpling, and audio-reactive projects that use FFT. On the back, we include a small trimmer pot to adjust the gain.
