Bottom Port PDM Digital Output Multi-Mode Microphone
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.
