ACMD9752BT

RYD ACMD9752BT is a Φ9.7×5.2mm unidirectional electret condenser microphone operating at 1.5V single-cell supply for battery-powered portable medical devices. -47±4dB sensitivity, 680Ω low output impedance, 58dB SNR, 100Hz–10kHz response. Enables direct interface to low-voltage medical ASICs and coin-cell powered designs without boost converters. Solder terminal for compact PCB layout. Unidirectional pattern reduces ambient clinic noise in patient-worn and handheld diagnostic tools. Manufactured under RYD ISO9001 with RoHS compliant materials. Customization available: medical-grade material compliance, ultra-low leakage current screening, custom low-impedance matching, biocompatible housing, and sterilization-compatible variants. Supports portable stethoscopes, spirometers, hearing test devices, and bedside voice recorders.
