- This electret microphone amplifier outputs around 200 mVpp at normal talk volume (approximately 6 inches away), making it ideal for devices needing a "line level" input without clipping, or up to 1Vpp, suitable for microcontroller ADC readings. The rail-to-rail output allows for an increase up to 5Vpp in noisy environments. - Perfect for various audio applications including voice changers, audio recording/sampling, and audio-reactive projects. A trimmer pot on the back enables precise amplification adjustments, ranging from 25x to 125x. - The amplifier features a fully assembled and tested board, integrated with a 20-20 kHz electret microphone for immediate use. - Utilizing the MAX4466 operational amplifier specifically designed for audio applications, this amplifier ensures exceptional noise reduction, delivering high-quality sound that is cleaner and less scratchy compared to other microphone amplifier breakouts. - With its compact size and reliable performance, this microphone amplifier can significantly enhance your audio projects, providing clarity and precision where it matters most.
