ICS-41350

Bottom Port PDM Low Power Multi‑Mode Microphone with High-AOP Mode

Note: The ICS-41350 is marked as EOL and is not recommended for new designs.

The ICS‐41350 is a low‐power, low‐noise digital MEMS microphone in a small package. It 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.
