Digital Multi-Mode Bottom-Port Surface-Mount Microphone with PDM Output
Дополнительная информация
The ICS-41351 is a multi-mode, low noise digital MEMS microphone. It consists of a MEMS microphone element and an impedance converter amplifier followed by a fourth-order Σ-Δ modulator. It features high SNR and 120 dB SPL AOP in all operational modes including Low Power (AlwaysOn), Standard, and Sleep modes. The digital interface allows Pulse Density Modulated (PDM) output of two microphones to be time-multiplexed on a single data line.
