Infineon’s XENSIV silicon microphone IM69D is a digital high performance MEMS microphone with 105 dB dynamic range and an output signal with high linearity, based in Infineon’s dual backplate MEMS technology. Microphones are no longer a limiting factor for active noise cancellation headphones.  XENSIV silicon microphone IM69D in such systems enables effective noise attenuation, clear reference audio signal, and low frequency noise cancellation.
