Top Port PDM Digital Output Multi-Mode Microphone

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.

The ICS-41351 has multiple modes of operation: Low Power (AlwaysOn), Standard and Sleep. The ICS-41351 has high SNR and 120 dB SPL AOP in all operational modes.

The ICS-41351 is available in a standard 3.5 × 2.65 × 0.98 mm surface-mount package. It is reflow solder compatible with no sensitivity degradation.
