The T3902 is a low-power, low-noise digital MEMS microphone in a small package. The T3902 consists of a MEMS microphone element and an impedance converter amplifier followed by a fourth-order Σ-Δ modulator. The pulse density modulated (PDM) interface allows two microphones to be time multiplexed on a data line using a single clock.

The T3902 has multiple modes of operation: High Performance, Low Power (AlwaysOn), Standard and Sleep. The T3902 has low power and high SNR in all operational modes. It has 126 dB SPL AOP in High Performance mode, and 120 dB SPL AOP in Standard and Low-Power modes.

The T3902 is available in a small 3.5 × 2.65 × 0.98 mm surface-mount package. It is reflow solder compatible with no sensitivity degradation.
