ICS-41351 Multi-Mode Microphone

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 microph.
