Overview
The T5808 is a multi-mode, low noise digital MEMS microphone in a small package which consists of a MEMS microphone element and an impedance converter amplifier followed by a fourth-order Σ-Δ modulator. The digital interface is a MIPI Alliance SoundWire® compliant interface which allows bi-directional data flow.
It has multiple modes of operation: High Quality, Low Power Listen (Always-On), Concurrent and Idle (sleep). The T5808 has high SNR and high AOP in all operational modes.
The T5808 is available in a standard 3.5 × 2.65 × 0.98 mm surface-mount package. It is reflow solder compatible with no sensitivity degradation.
