The microphones also feature matching phase responses and matching sensitivity, suiting them for stereo recording and simplifying their integration into systems. Sensitivity tolerance is ±1dB.
Both devices incorporate Wolfson’s proprietary CMOS / MEMS membrane technology. The technology enables high reliability and high performance in a miniature, low-profile package. They’re designed to withstand the high temperatures associated with automated flow solder assembly processes, which often damages conventional microphones.http://www.wolfsonmicro.com
