The new C928 type MEMS microphone from TDK is distinguished by its particularly high signal-to-noise ratio (SNR) of 66 dB(A) in the frequency range between 20 Hz and 20 kHz. It is thus particularly well suited for demanding applications in smartphones. The high SNR significantly improves the audio quality of distant sound sources, for instance when using the speakerphone or recording videos.
In conventional microphones, an improved signal-to-noise ratio usually leads to a sharp rise in non-linear distortions at high sound pressures. Thanks to the innovative design of the C928, a distortion factor of only 1% is produced even at a sound level of 131 dB. That makes it equally suitable for recording extremely loud sound sources.
The microphone features a footprint of 3,35 x 2,5 mm and an insertion height of only 1 mm. Thanks to its symmetrical output, it offers high immunity to interference. Its operating voltage is between 1,6 V and 3,6 V, and its maximum power consumption is 140 μA.
