TDK InvenSense T3903 Multi-Mode Microphone
TDK InvenSense T3903 Multi-Mode Microphone is a low noise digital MEMS microphone in a small package. This microphone consists of a MEMS microphone element and an impedance converter amplifier followed by a fourth-order Σ-Δ modulator. The T3903 microphone comes with high quality, low-power (AlwaysOn), and sleep modes of operation. This multi-mode microphone meets a high Signal to Noise Ratio (SNR) in all operational modes. The T3903 microphone also meets 133dB SPL AOP in high-quality mode and 120dB SPL AOP in low-power mode. Applications include smartphones, microphone arrays, tablet computers, and cameras. FEATURES
