Introduction

AI Translation

T3902 is a low-power, low-noise digital MEMS microphone in a compact package. It consists of a MEMS microphone element, an impedance-converting amplifier, and a fourth-order Σ-Δ modulator. The PDM interface allows two microphones to be time-division multiplexed on a single data line using one clock. The T3902 supports multiple operating modes: high-performance mode, low-power (always-on) mode, standard mode, and sleep mode. It delivers low power consumption and high SNR across all operating modes. The acoustic overload point (AOP) is 126 dB SPL in high-performance mode, and 120 dB SPL in standard and low-power modes. The T3902 is housed in a compact 3.5×2.65×0.98 mm SMT package. It is reflow solder compatible with no degradation in sensitivity.
