Microphones Procurement Notes

Verify the specific suffix (e.g., G10) against official Knowles documentation to confirm exact sensitivity tolerances and electrical characteristics. Ensure compatibility with the target operating voltage of 1.3 V and interface requirements before integration. Cross-reference datasheet revisions to confirm RoHS compliance status and material declarations.

Microphones Selection Notes

Select this component when an omnidirectional response is required for compact analog audio sensing. The low profile and small footprint suit space-constrained designs. Confirm that the 4.4 kOhm impedance aligns with the preamplifier input stage. Validate that the 100 Hz to 10 kHz frequency range meets the application's bandwidth needs.

Microphones Part Context
