Wolfson's new family of digital MEMS microphones
Wolfson Microelectronics plc has today confirmed that it will introduce its new family of digital silicon micro-electro-mechanical systems (MEMS) microphones.
AlreThe WM7210 and WM7220 digital MEMS microphones will complement Wolfson's high volume family of analogue MEMS microphones which were introduced in 2009. Based on Wolfson's proprietary CMOS/MEMS membrane technology, the new digital devices will deliver high reliability and performance, and can withstand the high temperatures needed for automated flow solder assembly, which can damage conventional microphones.
