OVERVIEW

The T5919 is a multi-mode, low noise digital MEMS microphone in a small package. The T5919 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.

The T5919 has multiple modes of operation: High Quality, Low‑Power (AlwaysOn), and Sleep. The T5919 has high SNR in all operational modes. It has 135 dB SPL AOP in High Quality Mode and 120 dB SPL AOP in Low‑Power mode.

The T5919 is available in a standard 3.5 × 2.65 × 0.98 mm surface-mount package. It is reflow solder compatible with no sensitivity degradation. The package integrates a Particle Ingress Filter (PIF) for enhanced robustness to environmental contaminants such as water and dust.
