Microphones Procurement Notes

Verify the complete part number including the suffix XTMA1 to ensure correct tape-and-reel packaging configuration. Confirm that the design supports the specified 1.62 V to 3.60 V supply range and PDM interface timing requirements. Check for RoHS compliance status if required by specific regional regulations. Ensure ESD protection measures are adequate during handling.

Microphones Selection Notes

Select this component when automotive qualification under AEC-Q103-003 is mandatory. Choose this model for applications requiring a balance of high sound pressure level handling and low power usage. Consider the 3.50 x 2.65 mm package size for space-constrained PCB layouts. Verify compatibility with the target microcontroller's PDM clock and data line capabilities.
