ICS-41350 Datasheet

Bottom Port PDM Low‐Power Multi‐Mode Microphone With High AOP Mode

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.

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.

The ICS‐41350 supports ultrasound applications in High Performance Mode. It has an extended ultrasonic response up to 40 kHz with high SNR.

The ICS‐41350 is available in a small 3.5 × 2.65 × 0.98 mm surface‐mount package. It is reflow solder compatible with no sensitivity degradation.
