T5838 - TDK

T5838 Bottom Port PDM Digital Output Multi-Mode Microphone

The T5838 is a multi-mode, low noise digital MEMS microphone in a small package. The T5838 consists of a MEMS microphone element and an impedance converter amplifier followed by a fifth 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 cloc.
