MEMS Microphone Signal Conditioning IC

The NSC62XX and NSC63XX series sensor signal conditioning ICs are developed for MEMS silicon microphone sensors. It is mainly used to provide bias driving voltage for the MEMS silicon microphone sensor, and amplify or digitalize its output signal. By 2020, the annual shipments of these two series of chips have reached 450 million units, which are widely used in various consumer voice systems such as TWS and smart speakers.
