Its high SNR improves the audio quality considerably when the signal source is distant from the microphone, such as in video recordings or hands-free talking.
Thanks to the innovative design of the C914, the distortion is no more than one percent even at a sound volume of 128 dB. In contrast to this, an improvement of the signal-to-noise ratio of conventional microphones as a rule leads to a strong rise of the nonlinear distortion at high acoustic pressures.
Besides its outstanding performance features, the microphone has a footprint of only 3.35 x 2.5 mm² and an insertion height of 1 mm. At a supply voltage of between 1.64 and 3.6 V DC, its current consumption is only 300 µA. The output impedance of this RoHS-compatible component is 200 Ω.
Main applications:
-Smartphones and consumer electronics devices
Main features and benefits:
-Signal-to-noise ratio of 65 dB(A)
-Low distortion even at sound volumes of 128 dB
-Compact footprint of 3.35 x 2.5 mm² and an insertion height of 1 mm
