CS7331P
Miniature Bottom Port Analog MEMS Microphone
Features
Description
• High acoustic overload point (AOP, 124-dB SPL)
• High signal-to-noise ratio (63-dB SNR)
• Low variation in sensitivity (±1 dB)
• Low current consumption (55 A)
• Analog output
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.
• Bottom-port LGA package
• 1.6- to 3.6-V supply
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.
