The ICS-41352 is a multi-mode, low noise digital MEMS microphone in a small package. The ICS-41352 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-41352 has multiple modes of operation: Ultrasonic, Low-Power (AlwaysOn), Standard and Sleep. The ICS-41352 has high SNR in all operational modes. It has 120 dB SPL AOP in all performance modes.
In Ultrasonic Mode, the ICS-41352 has an extended ultrasonic response up to 85 kHz with high SNR. The ICS-41352 is available in a small 3.5 × 2.65 × 0.98 mm surface-mount package. It is reflow solder compatible with no sensitivity degradation.
