#MEMS: "Microphones integrate interchip sound"

Micro-electro-mechanical system (MEMS) pioneers Analog Devices just introduced their first solid-state microphone two years ago, but already it is ploughing new furrows with the world's first MEMS mic to use a state-of-the-art digital interface, rather than the legacy interface of non-MEMS mics. Look for MEMS microphones to displace electrets in all but the most cost sensitive applications by 2012. R. Colin Johnson @NextGenLog


Analog Devices' 441 iMEMS digital microphone has a tiny silicon diaphram contained on a separate die measuring just one square millimeter.

Analog Devices Inc. (ADI) aims to bring high-fidelity audio to industrial, business and consumer applications with the world's first micro-electro-mechanical system chip to package a MEMS microphone with an industry standard 24-bit data integrated interchip sound—I2S—interface...
