ICS-41351
DESCRIPTION
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: High Performance Mode, Standard, Low Power (Always On), and Sleep. The ICS-41351 has 130 d B SPL AOP in High Performance Mode, and 120 d B SPL AOP in Standard and Low Power modes.
The ICS-41351 is available in a standard 3.5 × 2.65 × 0.98 mm surface-mount package. It is reflow solder patible with no sensitivity degradation.
