Microphones Procurement Notes

Verify the NRND status before finalizing designs, as this indicates the component is not recommended for new designs. Confirm RoHS compliance details and moisture sensitivity levels during procurement. Ensure compatibility with existing PCB footprints and soldering profiles. Check for any specific handling requirements due to the MEMS technology.

Microphones Selection Notes

Select this model when analog output is required instead of digital PDM. Consider the low operating current for battery-powered applications. Evaluate the 65 dB SNR against system noise floor requirements. Ensure the bottom port orientation fits the mechanical enclosure design constraints.
