ICS‐40181

RF‐Hardened, Low‐Noise Microphone with Top Port and Analog Output

GENERAL DESCRIPTION

APPLICATIONS

The ICS‐40181 is an analog MEMS microphone with high SNR

and enhanced RF immunity. The ICS‐40181 includes a MEMS

microphone element, an impedance converter, and an output

amplifier.



Smartphones

Tablet Computers

Wearable Devices

Still and Video Cameras

Bluetooth Headsets

Notebook PCs

Other high‐performance specification include a linear

response up to 124 dB SPL, tight ±1 dB sensitivity tolerance

and enhanced immunity to both radiated and conducted RF

interference.
