CS7331P - Miniature Bottom Port Analog MEMS Microphone

Cirrus Logic

General 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.

Key Features

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.
Bottom-port LGA package.
1.6- to 3.6-V supply.
