WM7216E
Low Power Top Port Digital Silicon Microphone
DESCRIPTION
The WM7216 is a low-profile digital silicon microphone, optimised for use with low-power ‘Always-on’ voice control applications, such as Cirrus Logic® SoundClear™ software.
The WM7216 supports two operational modes, selected according to the applied clock frequency.
‘Voice’ mode provides low current consumption, and sufficient SNR performance for speech recognition algorithms.
‘Hi-Fi Record’ mode offers wide dynamic range, and classleading THD performance.
Operation in the ultrasonic band is also supported at high clock frequencies.
The WM7216 incorporates Cirrus Logic proprietary
CMOS/MEMS membrane technology, offering high...
