Description
Description Unit Mini PDM is a digital MEMS silicon microphone based on PDM (Pulse Density Modulation) signals. It features high signal-to-noise ratio, high sensitivity, low power consumption, strong RF interference immunity, and smooth frequency response. The microphone automatically switches states (power-off / active / sleep) according to the clock frequency, making it suitable for audio data acquisition in wearable devices and smart digital devices. Features PDM signal output (CLK/DAT) High sensitivity and high signal-to-noise ratio Low power consumption Strong RF interference immunity LEGO-compatible Includes 1 x Unit Mini PDM 1 x HY2.0-4P Grove Cable (5cm) Applications Spectrum analyzer Audio recording Sound level meter Specifications Specification Parameter Digital Mic SPM1423 Sensitivity 94dB SPL@1KHz Typical: -22dBFS SNR 94dB SPL@1KHz, A-weighted Typical: 61.4dB THD 100dB SPL@1KHz Typical: 1% Operating Current 600µA Enclosure Material Plastic (PC) Product Size 24.0 x 24.0 x 13.0mm Product Weight 4.0g Package Size 138.0 x 93.0 x 7.0mm Gross Weight 8.0g Learn and Documents → DOCUMENTS
