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.
