Microphone Low Noise Audio Preamplifier Circuit

Published:2011/7/18 6:50:00 Author:Sue | Keyword: Microphone, Low Noise, Audio, Preamplifier

As seen in the figure, MC2830 will compose audio circuit. Traditional audio circuit cannot tell the difference between audio signal and noise signal. When it is very noisy, it is always the switch that make the noise. To avoid such disadvantage, we use different audio and noise wave forms. Audio wave form always has wide rangeability while noise wave form is more stable. Audio activation is decided by R6. If R6 changes from 14K to 0.7K, audio activation's sensibilitywill become lower.   (View)
