T3903

Analog MEMS Microphone with High SNR in Small Package Size

The T3903 is a multi-mode, low noise digital MEMS microphone in a small package. The T3903 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 T3903 has multiple modes of operation: High Quality, Low‑Power (AlwaysOn), and Sleep. The T3903 has high SNR in all operational modes. It has 133dB SPL AOP in High Quality Mode and 120 dB SPL AOP in Low‑Power mode.

The T3903 is available in a standard 3.5 × 2.65 × 0.98 mm surface-mount package. It is reflow solder compatible with no sensitivity degradation.
