High Performance Digital MEMS Microphone
[Overview and Design Intentions]
This is a microphone of dimensions 4 mm x 3 mm x t1.2 mm. It has realized a size-reduction and improved performance when compared to our existing product (4 mm x 3 mm x t1.5 mm).
The features are: Low current consumption / High SNR / Flat low-frequency characteristics / Low distortion.
Specifically, current consumption has been reduced to 0.46 mA Typ, which is 1/2 or less than in our existing product.
Even lower current consumption is possible when mode switching using the clock frequency.
