Microphones Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the AEC-Q103 qualification status aligns with your project's automotive grade requirements. Check for any recent lifecycle notifications or end-of-life notices directly from the manufacturer before finalizing procurement plans.

Microphones Selection Notes

Select this component when an analog output is required rather than digital PDM interfaces. Consider the 64 dBA SNR and -38 dBV sensitivity for applications needing balanced audio quality without excessive amplification. Ensure the PCB layout accommodates the TLGA-4-2 footprint and allows for bottom-port acoustic access.
