T5818 Description
The T5818 is a multi-mode, low noise digital MEMS microphone in a small package. The T5818 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.
