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.
