ICS‐41350

Bottom Port PDM Low‐Power Multi‐Mode

Microphone With High AOP Mode

APPLICATIONS

GENERAL DESCRIPTION



Smartphones

The ICS‐41350 is a low‐power, low‐noise digital MEMS

microphone in a small package. The ICS‐41350 consists of a

MEMS microphone element and an impedance converter

amplifier followed by a fourth‐order Σ‐Δ modulator. The pulse

density modulated (PDM) interface allows two microphones

to be time multiplexed on a data line using a single clock.

Security and Surveillance

The ICS‐41350 has multiple modes of operation: High

Performance, Low Power (AlwaysOn), Standard and Sleep.

The ICS‐41350 has low power and high SNR in all operational

modes. It has 126 dB SPL AOP in High Performance mode, and

120 dB SPL AOP in Standard and Low‐Power modes.
