Microphones Procurement Notes

Verify the specific suffix (e.g., BP) against the manufacturer's current datasheet to ensure compatibility with required packaging or environmental standards. Confirm that the operating voltage range aligns with the target system's power supply rails before integration.

Microphones Selection Notes

Select this component when a digital PDM interface is required to reduce analog noise susceptibility. The bottom ported design facilitates compact PCB layouts where top-access ports are obstructed. Ensure the application environment accommodates the specified 100 Hz to 10 kHz frequency response.

Microphones Part Context

This part belongs to Ole Wolff Electronics' digital MEMS microphone series, designed for cost-efficient voice capture applications. The product line emphasizes high signal-to-noise ratios and robust performance in consumer electronics requiring reliable omnidirectional audio input.

Microphones Replacement Considerations

Direct substitutes require matching PDM digital output, similar sensitivity (-26 dB), and compatible supply voltage ranges. Verify pinout compatibility and acoustic dimensions to ensure mechanical fit without redesigning the host PCB.
