T5919 Bottom Port PDM Digital Output Multi-Mode Microphone APPLICATIONS GENERAL DESCRIPTION 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.
