Description
The CS7331P is a low-profile analog MEMS microphone. It
offers miniature dimensions and low-current consumption,
making it ideal for always-on, always-listening use in
space-constrained applications.
The CS7331P incorporates Cirrus Logic^® proprietary
CMOS/MEMS membrane technology, offering high
reliability and high performance. The CS7331P is designed
to withstand the high temperatures associated with
automated flow solder assembly processes.
The CS7331P is ideally suited to the Cirrus Logic
SoundClear™ suite of audio processing algorithms,
including speech recognition, voice trigger, and noise
cancelation.
The CS7331P is available in a 2.5 × 1.6 × 0.9-mm,
bottom-port LGA package, with a 0.25-mm port diameter. It
is ideal for portable applications such as noise-canceling
earbuds, smartphones, wearables, and cameras.
