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.
