Top Port PDM Digital Output Multi-Mode Microphone

APPLICATIONS

GENERAL DESCRIPTION

•

Smartphones

The ICS-41351 is a multi-mode, low noise digital MEMS

microphone in a small package. The ICS-41351 consists of a

MEMS microphone element and an impedance converter

amplifier followed by a fourth-order Σ-Δ modulator. The digital

interface allows the pulse density modulated (PDM) output of

two microphones to be time multiplexed on a single data line

using a single clock.

Security and Surveillance

The ICS-41351 has multiple modes of operation: High

Performance Mode, Standard, Low Power (AlwaysOn), and

Sleep. The ICS-41351 has 130 dB SPL AOP in High

Performance Mode, and 120 dB SPL AOP in Standard and Low-

Power modes.
