WM7216E - Low Power Top Port Digital Silicon Microphone

Datasheet Summary

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.

Features

  • High SNR (63dB).
  • Low variation in sensitivity (±1dB tolerance).
  • Low current consumption - 10μA (Sleep) - 290μA (Voice mode) - 980μA (Hi-Fi Record mode).
  • PDM digital audio output.
  • Stereo/array operation.
  • Proprietary ADC technology - Reduced clock-jitter sensitivity - Low noise floor - Stable in overload condition.
  • Top Port LGA Package.
  • 1.62V to 2.0V supply.

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 reliability and high performance in a miniature, low-profile package.
