- Secure communication equipment in high-interference environments
Procurement Notes
Verify the specific datasheet version from PUI Audio, Inc. to confirm pinout compatibility and mechanical dimensions. Ensure the design supports the required 1.5 V to 3.6 V operating voltage range. Confirm that the application environment allows for proper bone conduction coupling to achieve the specified sensitivity levels.
Selection Notes
Select this component when bone conduction sensing is required rather than traditional air-coupled microphones. Consider the analog output requirement and the specific frequency range of 100 Hz to 8 kHz. Evaluate the need for integrated noise cancellation in noisy operational settings.
Part Context
This part belongs to the MEMS microphone category from PUI Audio, Inc., specifically engineered for vibration-based signal acquisition. It differs from standard acoustic microphones by focusing on structural vibration transmission through bone tissue for enhanced signal clarity in challenging acoustic conditions.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Direct replacement requires matching the bone conduction sensing mechanism, analog output type, and physical mounting configuration.
